This channel just breaks the internet with such huge information and knowledge. it's basically a masterclass for free. thanks
Thanks so much! Kudo's to all the people we mentioned in the thanks at the end though.
@@team2films 0:37 green is not a primary color lol. The primary colors are yellow, red, blue
@@RustyShackleford9000 Thanks for watching and commenting. I can understand why you'd think that, but green actually is a primary colour. Primary colours 'are sets of colors that can be combined to make a useful range of colors'. Different colour systems use different primary colours. For example in print Cyan, Magenta and Yellow are the primary colours used. In additive colour Red, Green and Blue are used as the primary colours.

Thanks again for watching and commenting.
@@RustyShackleford9000 lol
Hello, a big thanks to everyone who has pointed out that subtractive saturation can also be created with a single node set to hsv and then changing the gain of just the green (saturation) channel. We're calling that method hSv. It's a great tip and our apologies for not including that in the video. It doesn't change the fact that HueShift is a great tool that adds value to the process and speeds up your work! Thanks once again to everyone who has watched and commented. We appreciate you all!
You’re great🙏🏻
Thank you for sharing.
We are all here to learn.
Keep it up👍🏻🙏🏻🫶🏻
THIS is how Color Grading Tutorials should be done! Thorough explanation of how Things Work and why you do what and compare different methods and explain the effects of the techniques on the footage. Great channel
Thanks so much. You get us! 😄 It’s great to have you here.
@@team2films its just so good to NOT See someone pushing colors around wildly talking about "Juice"....If you know who I mean 😀
I'm two films in with Kaur, Jason, and Stefan Ringelschwandtner's DCTLs and I'm never going back to the "old ways" that involved complex node trees. The bang for your buck is a no-brainer.
That's great to hear. The convenience they bring to your workflow is well worth it.
I knew I could trust this guy because his video has very good coloring. No bright red and blue LED lights blasting out the background like most of the CZcams How-to crowd. Thanks!
Haha, thanks so much. It's great to have you here, we really try to focus on the teaching rather than the dazzle! Btw, please note there is a simpler way to do Sub Sat using the hSv method described in the comments.
Yea this is insane. Color is insane. Thanks for overloading my brain. I'm having to replay this 42 times to get the message in my thick skull.
Ah thanks so much! Yeah it's pretty packed, so replay as many times as you want!
Welcome DaVinci Resolve 19, where you can do it with one slider. Awesome update, and awesome content from you. Cheers!
Hahha, yeah almost! Some of these new features are pretty wild!
I'm only 3 mins in and already feel blown away by how well this information has been presented and explained. Subscribed!
Thanks so much! We're so glad it's hitting right. Great to have you here.
Thank you as always for the nuanced run through and explanations - the interviews were a great addition too!
Thanks Ed. Much appreciated. Yeah, the interviews were a nice surprise. Really enjoyed hearing Jason's perspective on grading.
@@team2films yes always nice to see the faces behind these things and understand where they're coming from. I've seen a few vids on this area of saturation but this was by far the best. Thanks again, love your channel.
Mind blowing! Bless you and your team for this info!
Our pleasure, thanks for watching.
You guys are till heavily under appreciated. I hope you gain the traction you deserve. Always top-notch quality. Thank you!
That's really kind of you. We're happy to know people are enjoying the videos.
You Guys are soooo informative! What an amazing channel!
Thanks so much. Kind of you to say.
Seeing these videos of you, feels like i did not miss and cinema school. Huge respect and a huge thank you.
Thanks. Glad it's helpful. More topics coming soon!
I met an editor/colorist a few weeks ago and this video is spot on. He also talked alot about great DCTL is and owns several plugins for it.
Thanks so much Tom. Appreciate you commenting.
As the beginner colorist,this channel is very helpful for learning about colorgrading. Thank you very much for making this content
So glad it's helping on your colour grading journey.
The knowledge you shared for us is another level.Thank you so much

So much great information, delivered in such a clear way!
Thank-you very much, appreciate you watching and commenting.
A phenomenal video! I learned a lot, thank you!
So happy to hear Martin. Thanks for watching.
Really interesting - I know both Jason and Kaur - really helpful and smart guys. I proposed the question to Cullen of why we tend to not fix the saturation in footage first, then decide on the amount to apply?
My opinion is pretty much what Jason and Kaurs tool actually does. I don't believe that saturation is something that can be a one knob fix in regular sat tools using any color space.
I also have the opinion that camera manufacturers, and pretty much every job on set is to nail skin tones - especially in camera, the digital saturation and how it is used is to push the best ( what they think is the best ) skin tone in their saturation decisions. Camera manufactures know this, and will target skin as a selling point.
Now because of that fact - a lot of the rest of the image may, or may not have the correct balance in saturation, and become either too saturated or undersaturated. Where as I mentioned - one knob isn't going to fix it.
The filmic aspect - the fact that light is being pushed through the film - you want something redder or greener - a film camera can't just add saturation - they need to increase the amount of color in the process, by adding density ( literally ) which of course will let less light through and it becomes darker.
Keep up these great videos - you are going to get a large following really quickl and the sucess will be well deserved. cheers
Thanks for watching Jim and for your encouraging comment. Jason and Kaur are great. Yeah, it's great to have such a variety of cool tools for addressing saturation. We are spoilt! And Kudos once again to Cullen for his work on this.

Best overall explanation ever....
Thanks so much, great to have you here.
I saw some guys use the second method, but instead of using nodes to separate the V-Channel they disabled these channels in the nodes drop-down menu. I'm not entirely sure if this approach has any differences, but it is way easier as you only need one node and it gives you subtractive saturation and similar results.
I can't say for sure without seeing the method you are referring to, but it might be performing a type of additive saturation (not subtractive).
@@team2films Yeah in a single node set colorspace to HSV with channels 1&3 disabled leaving only channel 2 enabled to control saturation via the gain wheel. Scopes behave the same way as method two so looks to be subtractive.
@@InfiniteRealms this is what I do as well
In fact you can see it in this video! When you adjust the green gain channel in your HSV node, the scopes look identical to when you're adjusting the gain at the end@@team2films
Update: Yes, that method does work. @MrWariwckJones kindly helped us out with that.
Great video, thank you!

Brilliant! Thank you ! I liked and sub'd.
Thanks so much. Welcome!
One of the greatest tutorial channels for DaVinci! Remarkable job! One little correction i must mention because I am shooting on film a lot. 3:26, The density on a film is not coming from the saturation or the color richness on a negative film. The density is coming from the exposure. More overexposed the negative, the dense (thick) it will be. Underexposed means less dense (thin). Again. GREAT GREAT job guys. thanks for this wonderful video!
Correction. It is somewhat relative with the color richness also, but mainly the density is exposure.
Heya. Thanks so much for watching the video and leaving such a kind comment.
Some thoughts. Yes, density is a consequence of exposure, but exposure is also a consequence of saturation. Highly saturated colours are also typically highly exposed. Hence, the reason why density is being associated with saturation.
Saturation occurs when there is a difference in the exposure of the colour records. The greater the disparity the higher the saturation. So in the instance of a highly saturated blue... the saturation is caused by a dense magenta and cyan record.
Would love to hear your thoughts.
@@team2films "Highly saturated colours are also typically highly exposed". If you think about light reflectance, it should be other way round. Objects with highly saturated colors reflect less light, because they absorb more wavelengths that they reflect in comparison with pale and white colors. So, they should be less exposed on film.
@@Fedor_Dokuchaev_Color thanks for commenting and joining this thread. Yes, you are right that saturation does technically decrease exposure, many highly perceptually saturated colours in an image have above average exposure.
Please allow me to explain what I mean.
It all depends on your frame of reference. Yes, a highly saturated colour has less exposure than pure white therefore it has a lower exposure. But in the example provided above of a strong blue it has strongly exposed magenta and cyan records. That’s 2 out of three color records that are near fully exposed. As the most strongly saturated colours have the highest disparity between colour records, that’s why density (or exposure) is so strongly associated with saturation on film.
I look forward to hearing your comments.
@@team2films Thanks for your answer. True, but on the other hand, if you would take a picture of a super saturated blue sky and absolutely underexpose the frame, no matter how much saturated would be the sky, the negative would be super thin :D cheers.
This is above my skill level, but still, what a beautiful tutorial. Thank you for such elegant teaching.
Ah thank-you Eric. That's really kind of you to say. When you are ready, it's there for you! In the meantime thanks for watching. It's great to have you here.

Awesome, thank you!
Thanks for these jewels 💎 man! 👏🏼👏🏼👏🏼
Glad you liked it :)
@@team2films One would expect though that a world class software like davinci would already have such a plug-in!(Simplyfied) let’s hope to an uptade soon!
@@blertonsaraciYeah agreed, it would be great if these features were integrated in the future. In the meantime though, It’s pretty amazing though that DaVinci’s node based engine makes it possible to perform these kind of operations. That’s also why Blackmagic has developed the DCTL api. So other developers can augment Resolve with additional functionality. It would perhaps make the program more difficult to use if it tried to incorporate tools for every style of colour grading.
@@team2films Absolutely, you are right! Just that with the time,(as you briliant guest mantioned) you start feeling/understandig the foundamentality of density, and it’s definitive belonging in the DaVinci world!
Absolutely amazing advanced tutorial here!
I find it very difficult to find expert knowledge in this field because the rise of influencers lately..
I am curious if you have a paid course in this format?
Also I would love some help in the realm of sharpening! There are many ways to tackle it but most leave me feeling with gopro like footage.
Thanks again!
Hello! Yes, we have a course! It focuses on professional editing in DaVinci Resolve but it also tackles basic colour and audio work. There will be more details about that next week.
We love requests and suggestions, thank-you.
You can do this easily with one node in davinci without the plugin. Create a node in HSV color space, deselect channel 1 & 2 and increase the gain.
Unfortunately, that method does not yield the same result. Subtractive saturation should have a non-linear response across different luminance and saturation values. The method you described applies saturation in a more linear manner, affecting darker and less saturated colours more than desired. It yields broadly similar results with subtle adjustments, but does not look as good when stronger adjustments are made.
Hope that helps! Feel free to try both methods and see how it affects the image and parade scopes.
I'm a beginner but I understand how this is really useful, thank you!
I know it's a completely different argument but I would really found something so polished and simple for colour animation of the subtitles like auto highlight the current spoke word...
Great idea! Thanks for watching.
@@team2films Thank You to You for this professional information made for beginners!
So I've played around with this and found out that setting a node to HSV and just raising the green channel yields the exact same result. When set to luminosity on a single hsv node it's identical to the presented node tree when just raising y gain. What I experimented with is splitting HSV and feeding Saturation into the Value channel and subtracting it that way. Beforehand I multiply the Value channel with the Saturation channel to avoid ultra saturated colors at the very extremes of the luminance ranges. The result is - in my opinion - the most flexible and the most pleasing looking. The corresponding node tree can easily be saved as a power grade and just needs one or two nodes to be touched to get nice results. It also has the benefit of lowering the gain of saturated colors, without adding saturation you don't want. Just my 2 cents. Cheers!
Thanks so much for watching! Yes we’re aware of that technique. There is a comment in the description about it. Doesn’t mention the multiply technique though. You can also use a curve instead of gain. That also gives you a roll off.
Subtractive saturation is also now implemented natively in resolve with the new color slice tool, and the film look creator.
The interesting part is, that I use a curve to bias how the luminance gets affected, the sky is the limit here. The gain then is just the to dial in an amount of said curve.
I think for someone like me who personally don’t like film grain or halation when emulating a film look, sub sat is the best way I can make my modern digital video look filmic combine with proper contrast curve that never hit true black at the bottom and true white at the top of the curve.
I personally will not 100% staying away from Sat vs Lum in HSL it’s sometimes can work as complimentary knob for HSV color space achieving that deep rich filmic look. You don’t want to over do it tho.
Awesome! Thanks so much for watching and commenting.
Amazing tutorial Leon! What is your keyboard model?
Thanks Gustavo. My keyboard is made by EditorsKeys. It's the Resolve model.
I use colour density DCTL from mononodes.
I use it too, I think the math involved is impressive, is very hard to break the image. the result is very nice colors especially with Hue Shift.
Is that the Color Shift package?
@@ronlinehfx yes.
Glad you are enjoying it. Stefan has done great work on those tools.
Excellent tutorial, thank you! I have just one question - is it not easier to switch the node to HSV, turn off channels 1 & 3, and apply Gain/Gamma to the same node instead of creating the layer mixers?
Thanks for watching. Yes, you're correct. That's another great way of producing a similar effect. 👍
Mononodes is a game changer, great tools which speed up the grades as well. It’s weird that Davinci hasn’t incorporated his tools yet.
Yeah, mononodes and PixelTools have done awesome with these tools.
Thanks very much for an interesting and informative tutorial. Do you think that DR will add this kind of functionality natively to a future update?
That's a great question. It's hard to say. Blackmagic are always innovating and adding new features to the Resolve but DCTLs will always have a place though.
They did just add a feature a day ago that people were asking for. I have a feeling we're going to see something like this for Studio users. I prefer to learn the hard way because knowing how coloring works gives one better control for unforeseen problems. The images he's working with were properly shot with correct lighting and white balance. Working with terrible footage may be more challenging even with the DCTLs plugins he's promoting.
Thanks for the video! Remembers me to the Technicolor Nodetree by the German channel Farbkanal. Does this have issues in a color managed DWG or aces project? I got this to work in rec709 timelines only jet :/
It works fine in different colour spaces. As always though, remember the tool will respond slightly differently. A grade created in one colour space won't copy to another, but it's broadly capable of doing the same things in either colour space.
Very nice explanation, makes me NEED to try the demo tool in my underwater footage, where color is often a big mess :) and a ton of nodes to work with ... thanks
Question: how is the response of the tool regarding Noise on the image ??
It's better than comparable methods (i.e. manually built qualifiers) as it's ranges flow nicely into each other.... but of course it depends on how bad your noise is.
Yeah, underwater footage can be challenging, especially with the colour loss.
@@team2films Challenging yes and I have a good setup, the main rule in underwater color grading is very much : don't go too far :):):)
Personaly I don't use qualifiers underwater
Any way, I tested a few clips, with 3 methods, classic color saturation/HSV Method/DCTL (demo), as I'm finishig a series of tutorials, and for sure one of my last items will be talking about color saturation substractive methods (deepness of colors without adding brignthness is a must, I wasn't aware of that.
As far as I can see, HSV + combination of HSL in the finish line of the color grading process gives almost the same result in two nodes as with DCTL as I don't have to deal with skin tones, so a bit more complex not using DCTL ... I have to investigate more :)
DCTL, is an amazing job well done, I'll have a word in the Tuto about the tool and the developper, and also your tuto because I won't paraphrase your's wich is cristal clear
thanks for all
@@gillescharvet Thanks so much.
is this the same way the new color slicer works in 19? i was trying it out last night and noticed the scopes were lowering when i increased the sat, which was confusing me.
if so , do you still see a reason to set your nodes up this way or will the channel slicer work ?
Yeah, the new color slice tool uses subtractive saturation. Check out our video covering it.
Thank you for the helpful insight on DCTL.
Are the DCTL parameters mapped to the Blackmagic Mini Panel?
Yes, they can be controlled with a mini panel
@@team2films Thank you.
great video!! curious if there are any subtractive saturation for adobe plug-ins
Good question, I've not researched it. Sorry!
Thank you very much for the video. I have one question. How does the “hard way” 5:35 differ from switching the node to HSV color space and then manipulating the S channel, i.e., the Green wheel and/or curve? I ask because I learned this very same technique from Cullen Kelly’s TouTube channel and it does appear to yield better results than additive saturation. Thank you again and congratulations on your excelent videos.
Pleasure, thanks so much for watching and commenting. That's a great question! Please post a link to the @CullenKelly video. I'd love to take a look. He's a fantastic source of information on colour grading.
It sounds like you a describing a method that still produces additive saturation but in a way that is more pleasing than the stock saturation tool in Resolve.
@@team2films Thank you so much for answering my question! Here's the Cullen Kelly video I was referring to:
czcams.com/video/bAAjyNHDpyo/video.html
I find the work you've been doing on your channel complements quite well what I learn from Cullen Kelly's videos, so I would love to hear back from you on this technique. Thank you again.
@team2films It's actually the same technique as described by @D_Aliban in an earlier comment 🙃
@@dlaimer Hello, thanks for your patience. We did some testing, and yes the single hSv method yields the same result as the complex node tree. Our apologies for not having included it in the video. If we ever make a follow up on subtractive saturation, we'll include that.
damn!
Having watched your great tutorial, and played with it a bit, and looking a lot ... I'm now frustrated that I can't work out how to replicate this in Photoshop! 🤣
Hahah! That's so funny! I'm sure there must be a way of doing it! For sure though there are times that I wish Lightroom or Photoshop worked more like Resolve. Would love to have tools like lift gamma and gain controls or Vs Curves in photoshop. Thanks for watching.
Mononodes has a great density dctl
Yeah, Stefan's tools are great too.
Thank you for the high quality instruction on saturation! I have a question, however, on the comment that Resolve Does not use subtractive saturation. When I use the HDR color wheels to saturate by pushing the Sat slider to the right. The waveforms move in what appears to be the same manner they move when using the node setup "shenanigans" demonstrated in The Hard Way (or the one HSV node technique that others have already pointed out, which does the same thing). Am I missing something? It appears the HDR wheels saturation IS subtractive. Thanks again for the time and effort to put this tutorial together!
Hello, sorry for the delayed reply. Wanted to take the time to test this. I can't seem to replicate subtractive saturation with the HDR wheels. Is there anything I should to replicate your setup.
When I use the HDR Sat slider and view a Y waveform it's true there is an overall decrease in the luminance of the image. However when you use the parades, you'll see that it is increasing the intensity of individual channels. HDR Saturation has a roll off in the highlights and shadows which will cause it to give a slightly different result than the regular primaries saturation slider, however beyond that I still appears to be operating as additive saturation in my tests, albeit with a slight decrease in overall luminance as the saturation increases.
Looking forward to hearing your feedback. Thanks so much for watching and for your kind comment. It's great to have you here.
I am total new to DVR, got the Studio version though. I got one question: What is the difference between the native DCTL tool and the HUEShift tool?
Sorry if this may appear a stupid question, as mentioned I am new to these kind of things. Thank you already.
Great to have you here. The DCTL is for loading DCTLs. You can’t do anything with it unless you load a DCTL. HueShift is a DCTL that you can load with it. There are many DCTLs, some free, some that you need to pay for. Hope that helps
What colour space are you using for your timeline on min 7:20? And have you already transform the log footage with a LUT? I cannot make it work on my project.
Hello! We’re using RCM to normalise the image. The timeline working colour space is DaVinci Intermediate. If you’ve not seen it, please check out our color management video :)
Thanks for this video. I copied your node tree a few times, but I'm having some issues. The first layer mixer does not cause the image to black when I set composite mode to Subtract. When I click the last color node between the two layer mixers, that is when I get a black image. Any idea what might be off?
Hello Chris! So sorry you are having problems. Not sure what the issue might be from the description. Try following the instructions in Cullen Kelly's mixing light article. It's a fantastic resource.
Is there a difference between the Pixeltools DCTL and the one from Mononodes ? I dont know which one came first, but they look like a perfect copy of each other.
They are even using both emojis to label the sliders.
Hello, yes there are similarities for sure. From what I understand, they use different mathematical methods, so a different engine under the hood. Pixeltools DCTL combines a bunch of different functions into a single DCTL. I believe the same functions are spread across several DCTLs in mono nodes - for example density, hue shift and sub sat are in separate DCTLs.
Jason and Stefan are both great colourists and make awesome tools.
In case i use the middle method on my grade, on what position would you advice me to put it, in the beggining, middle or end of the tree node??
Sub Sat is usually a secondary operation. So after your primaries.
Targeted adjustments, non-breaking, comprehensive scope of the tools: the way of the future?
Yeah, it's pretty good. Great work from Jason and Kaur.
Do you know how I could apply the subtractive saturation look to still images? Ideally using Lightroom CC on iPad?
No, Sorry, I'm not familiar with methods for doing that in Lightroom.
Great video, I'm hoping you can answer a question I haven't seen answered in Cullen Kelly's video or this one: how do we implement this feature with higher compression footage? I shoot Sony cameras (FX3 and FX6) and while both cameras color holds up very well in grading, as soon as I try to implement these subtractive color tricks, the footage completely falls apart. Macroblocks appear every where, colors get ruined, skin tones, flickery pixels, etc. It seems to be an issue with compressed footage, and much less of an issue with high quality prores or RAW. I figure there must be a way to use this trick with sony footage or other h264 based footage without completely breaking the colors. Do you know anything?
H 264 is a delivery codec, not for pro color grading or pro editing.
@AxelKozber It's difficult to provide a solution without more information but here's some things to consider. Most cameras employe a compression technique called chroma sub sampling where higher levels of compression are applied to the colour information than to the luminance information. As subtractive saturation operates exclusively on the colours in the image, it's more likely to reveal colour compression artefacts. Your cameras are capable of recording to different flavours of XAVC. It might be helpful to check your manual to work out which ones preserves the most colour information in the final file.
It is however perfectly possible to grade low bit depth - high colour compression files. Images cannot typically be pushed as hard though. Broader corrections are more likely to work rather than corrections with narrow qualifications to target a specific colour range, for example skin tones. There are 'tricks' to lessen these artefacts, like blurring qualifications, or qualifying based on luminance only... but at the end of the day, garbage in, garbage out (I mean that in the nicest possible way!) There are compromises that must be made.
Thank-you both for watching. I hope the comments above were helpful. Great to have you here.
@neilseiffer5155 Thanks for the comment. Yes, h.264 is a super common delivery format... but the codec might be more capable for professional work that you might have realised. Please allow me to share some thoughts and forgive me if they are things you are already aware of:
There are lot's of professional colour grading and editing workflows that extensively use h.264. Firstly because many prosumer grade cameras are used to supplement other cameras in production, but secondly because many professional cameras use h.264 compression. For example Sony's XAVC format (found in cameras like the FS7, FX9, etc) uses h.264 compression. In fact, XAVC is capable of recording 4:4:4. As a result h.264 is not just a delivery codec. It's extensively used as a capture codec in professional workflows. It's more accurate to say that H.264 is not typically used in high-end production.
Thank-you both for watching and commenting. It's great to have you here.
I always asumed saturation compensates for luminance, such that if you want to saturate your reds, the red color is added but a little bit of blue end green are subtracted to match the brightness. Wouldn't this be ideal.
It sort of does. Play with the native saturation tool and see how it affects a parade. The result can still broadly be considered additive saturation though. Subtractive saturation doesn't maintain luminance, it actually decreases.
What is the spherical colour model that Kaur mentions at the very end? The gen, zen, jen...couldn't catch it.
Chen (I think!). Try message him on his channel if you want more details.
@@team2films Thanks, yes he indeed confirmed it was called (Tieling) Chen👍
Perhaps it will provide a little more clarity when considering the Cullen Kelly 1 hSv node solution, considering that he often balances the saturation on this node with gamma AND gain.
The hSV method is great. It's capable of producing the same result as the more complex node tree we created. Sorry we didn't include it in the video too!
@@team2films No reason for an apology. I just wanted to respond to some comments that don't see the difference between your method and Cullen's method. Cullen then balances the saturation manually, while your node tree delivers a slightly better result out of the box.
@@jensgeumann7564 Ah thanks. That's kind of you! We did some more testing and it's possible to replicate the complex node trees results with the hSv method, but also at the same time there are some unique things you can do with either method too.
We're horrified by the prospect of sharing incorrect information 🤣 So we always appreciate people pointing out errors and helping us to give a more rounded impression of a given topic.
Resolve says "Unable to copy", when I try to install the demo.
WIth option two: how can you grade two different colors?
cheers
Tom
Hmm. PixelTools might be able to help with that. Re: the second question, you’d need to set up a second qualifier and a second sub sat node. You could mix them through a layer mixer.
I've simply been using the green gain channel on an HSV node to emulate film density on the advice of a few professional colourists. Can you explain why that much simpler method is different from your four-node solution? As far as I can tell, increasing Saturation in the HSV color space only lowers luminance values on my waveform, and renders the deeper, richer colours you get with your method.
@@team2films i did try both, and pushed them to an extreme. The waveform is identical for both methods 🤷♂️
@@MrWarwickJones Hmmm... I think I need to apologise here! I had tested both methods previously and yielded different results. However, I just tested it again and like you said it's yielding identical results. Perhaps I'd overlooked something in my first tests. Although the video doesn't specifically mention the hSv method, I'll add a pinned comment to the video suggesting the hSv method as an alternative to the complex method outlined in the video as that will give a better impression of different methods of producing sub sat.
Thanks for watching and commenting and for your persistence in helping this method bubble to light! PS I removed my incorrect comment so I don't leave bad information here in the comments!
does anyone know if it’s possible to do the same sort of thing in photoshop? i’d love to use subtractive saturation in my photo editing, and im not quite ready to fully switch to a davinci workflow for photography.
That's an excellent question. I'm not sure!
you can do HSV subtraction with only 1 node.... change it to HSV color space, disable Chanel 1 and 3, use gain to saturate colors. done!
Yes! Apologies that wasn't included in the video. Thanks for watching and commenting.
Could you be mor specific where to disable Chanel 1 and 3?
@@SeanHuangRealEstatethere’s no need to disable the other channels. Just only manipulate the gain in the second channel using the primaries bars.
@@SeanHuangRealEstate Yes of course!!!
When you change the node to HSV color space, you can also right-click the node and select the option "Channels" right below... this will open a window with 3 channels already checked, being channel 1, 2 and 3 respectively for H, S and V. Then you can simply uncheck channels 1 (for Hue) and 3 (for value)... now you have only Saturation channel working. Simply control the amount of saturation with your "gain" wheel on log wheels. (Gain wheel gives the best results, I tried using other wheels and they also work but breaks the image considerably. (hope it helps my friend)
@@arthurangenendt8959 Thank you very much for the detailed explanation! It looks like using this method we can change the overall subtractive saturation. If I want to change the saturation of a certain color, then I will need to use a qualifier and then repeat the above?
Would you be kind to share a Power Grade version of method 2 with us?
Non, sorry! We don't currently. Shouldn't be hard to build one yourself though. Follow the link to Cullen's article as well if you need more details.
Where is the best position int the node structure to bring in hue-shift tool ? After the first CST or after the last?
I'd usually put it where you normally put your secondary corrections.
@@team2films okey cool, i try out also its works stronger or in a other way when use it after the CST
@@team2films before your output to display space.

Thanks so much Cornelius.
Isn’t the issue the same in photography ? I wonder if lightroom supports substractive saturation or if there are workarounds / plugins for better film look emulation. (NOT shitty presets)
Hello, Sorry, I'm not sure if there are tools for doing this in Lightroom. Thanks so much for walking.
And it ends up looking like it was shot with a polarizer, which I think essentially cancels out reflected white light, achieving richer saturation. Is this fundamentally related? I'm grasping.
That's a good question. I think in this instance (using subtractive saturation to boost blue skies) it has had a similar effect to using a polariser (reducing stray light and deepening the colour of the sky). It's important to remember though that a polariser would have a different effect on an image captured with a digital sensor (additive colour) than it would with an image captured on film (subtractive saturation). There are lot's of other scenarios though where a polariser would not achieve the same result as subtractive saturation. @DarrenMostyn has a great video showing it on reds in an image.
Which is better? Hueshift or Colorshift? 2 different DCTL's but they seem to do the same thing....
That's a good question. They use different maths, and the Mononodes plugin is split into different DCTLs. So there are differences in workflow and there will be differences in the results too. I guess it's like two different cars, they have similar functions on paper. You need to go test drive them to see the differences.
Hope that helps.
@@team2films makes sense. Thanks for clarifying.
thanks, is there a free trial for hueshift?@@team2films
Is your version any different then mononodes version besides that yours is cheaper. Just curious
Firstly, not our DCTL! It's made by a gentleman called Jason Bowdach.
I believe they use a different mathematical function for performing the subtractive saturation. One other difference is that Mononodes splits the same functions contained in HueShift across a couple of different DCTLs. Jason's HueShift combines several functions into one single DCTL.
Stefan's tools (mononodes) are great too. If you get the chance to try both would love to hear what you think.
Hello. Thank you for such a detailed explanation Perfect theory demonstration. But if you will - can't this be done simply in one node? When you switch to HSV color space - just increase gain in G channel - and it will add subtractive saturation. I compared results and they looks identical. It is also possible to apply qualifier to the same HSV node to keep everything in single node, or just add second node with alpha qualifier, similarly to what you did in the video. In that case there will be just two nodes.
What are the cases when we need to build this nodetree with 6-7 nodes to achieve this result instead of directly increasing S channel in HSV node?
Also, am I right that you lowered red channel in HSV node just as a demonstration, because it doesnt affect the final result even if we leave hue channel untouched? Or I'm doing something wrong? Thank you!
You're welcome! Yes the single node method you describe does work. There's a pinned comment about that. Go ahead and use the simpler version. Also, now you can just use color slice in DR19. Technology has moved quickly since this video was made!!!
@@team2films oh, my bad! Don't know how i missed pinned comment! Anyway your node tree explained greatly how to substract and add channels, which may be helpfull in other more complex cases. Yeah, new Color Slice is really nice tool. But it's great to know how to do this manually. Thanks again!
@@tomibegabsolutely no problems. Yeah, you get our point exactly…. We wanted to show the ‘science’ behind it, to know how it works manually even if you got and use more automatic tools. Appreciate you watching and commenting. Thanks so much.
Hi guys. Did PixelTools offer a discount code?
It's currently $20 off. No further discount that we are aware of at the moment though. Sorry. But it's a great price for what you are getting.
@@team2films No problem. The price is fair. I'm just used to seeing ~10% discount from sponsorships.
Thanks for getting back to me, and great video. You managed to simplify some difficult concepts.
Is this applicable in photography
Yes, it is applicable! But I'm not sure how you would replicate it in a program like Photoshop. Perhaps there are similar plugins available?
Damn your videos are good (although the constant beeping over the interview with Jason was really distracting ☹️)
Ah 🤣 apologies. Thought the music would add some suspense to the interview. Noted for the future. Jason says some absolutely golden things in there though.
how can i do this in premiere pro?
Hello! We’re not aware of how to do this in Premiere. Maybe someone makes a plug-in that does this?
8:30 I don't understand what is the difference in just changing to HSV and increasing saturation (S), skipping all the other "doing/undoing" nodes.
Hello, thanks so much for watching! Firstly, this video shows you how to do Subtractive saturation for free! The DCTL is presented as an option, but we wanted to give you a completely free option too! We're trying to inform our audience, not just push a given solution.
Correction: You are correct! The hSv method does yield the same result! I did some further testing and I think I'd overlooked something in my initial test. My apologies for the misinformation and for not having included this method in the video.
Hey guys. Every time I build a subtractive saturation tree, I find the image breaks down. I get large, blocky noise when its turned down or past 1.4. Any thoughts?
Heya, sorry you are having problems. What kind of footage are you working with? It might perhaps be limitations of the codec you are using.
thank you for the reply! It's XAVC HS 4k on Sony FX3. After a CST converting slog 3cine to Davinci wide gamut @@team2films
This tool is kinda like using the printer lights?
Ooo, that's a good question. There are some similarities, i.e. it allowing you to manipulate primary colours. But printer lights won't left you shift hue, change density or saturation. So very different in that regard.
Anyone have an idea how to do this in Photoshop? I am about to sleep, but will try out some stuff, I guess working in CMYK mode is a start.
No, I'm so sorry! Not sure how to do this in Photoshop.
Is there not a demo? I just see buy option
Yeah, there's definitely a demo available!
@@team2films can you point me to it? I don't see any demo option on the website anywhere.
Sounds a lot like getting to the same location by a different route, equally to a different technique of personal preference, rather than any sort of technical advantage. There are many ways to get the same "look" so there is nothing really different that can be achieved with this tool or approach. leaving the process to be a matter of personal preference. Should there be a payment for personal preference of getting to the same result in about the same time? I'm not convinced it should. And for the price, its way to much.
Thanks for watching! Those are good questions... but here's some thoughts that might help:
- Subtractive Saturation is difficult to achieve without additional tools. It's a sought after look that people instinctively recognise thanks to decades of watching film. These techniques and tools offer a superior result than faking the look.
- Paying for tools to do something you can already do? I can walk to the office but it might take me 2 hours. A car can get me there in 30 minutes. Sometimes it's not the destination, it's the journey! Time is money for professional colourists and editors. Consistency is also important. If I was a woodworker, I can drill a hole with a hand drill... but if I've got 100's of holes to drill, a bench drill will help me do it more consistently. Even though it does the same thing as a hand drill, it's a worthwhile purchase.
Thanks again for watching and commenting. It's appreciated.
@@team2films Thank you for the reply.
I have few counterpoints.
- Subtractive Saturation is difficult to achieve without additional tools.
This was the same marketing argument said by other companies, and dispelled as a myth.
You can look at a pretty good Davinci resolve plug in called "Look Designer." Their whole marketing bit was about subtractive color and how it simulates film etc. I've tested the plug in a lot, and while its a nice feature, the end result was no different than what I was getting traditionally. You would not be able to tell the difference.
The "film look" subtractive color marketing was also done by the The Brim Linny lut pack sold for something like $600. This claim was easily debunked by a colorist from Australia by the name Juan Melara. He has tutorials online where he reconstructs these tools with ease in Resolve. And he also offers his own luts and power grades that mimic the film look very convincingly, and its all done in resolve. He shows how.
I've tried his power grades, I have made my own, and I assure you there is nothing mystical about subtractive color in digital world. It only makes a difference when you work with analog. Because that is where its real, in the digital we only simulate it by additive color grading and that can be done in many many ways.
Thank for the interaction. Cheers!
@@KrunoslavStifter Thanks. It's nice to be conversing about this stuff.
To further clarify, subtractive saturation as a mathematical operation is difficult to achieve without additional tools. There isn't a simple way to do it natively in Resolve. However as you say it is possible to emulate the look of sub sat, and that's often good enough. We're definitely not saying there is anything mystical about subtractive saturation :) It's a great technique, based on solid theory. Even though you can do it manually (which we hope we made that clear that you can in the video) there's still great value in DCTLs like Hue Shift that allow you to speed up and automate the process. It's one of many tools, and I'm sure a lot of people will find it valuable in their work. As Jason described, it's beneficial to be able to stay in the creative mindset while grading.
Thanks again for watching and commenting. Feel free to respond. Always interested to hear what other people think.
@@team2films Thanks.
"As Jason described, it's beneficial to be able to stay in the creative mindset while grading." I can't argue with that. That's true.
According to Resolve manual: "files are actually color transformation scripts that DaVinci Resolve sees and applies just like any other LUT. Unlike other LUTs, which are 1D or 3D lookup tables of values that approximate image transformations using interpolation, DCTL files are actually comprised of computer code that directly transforms images using combinations of math functions that you devise. Additionally, DCTL files run natively on the GPU of your workstation, so they can be fast."
Perhaps the speed of rendering is the main advantage that I see here, but look and feel is something that I don't see as unique. And you acknowledge that. By the way, I don't know if you are familiar with Fusion community called "We Suck Less" and their reactor Fuse for Fusion. They offer tones of free stuff that seems a lot more unique and advanced compared to this, and they offer is for free or vulentary donation. So you will pardon me for not feeling that value of this tool to be quite up there with that is offered.
That being said, seeing DCTL being expanded and offered custom tools to people is a good thing. I wish you the best in that. I just feel that its a bit over hyped for that it is as it is now. Although, I consider myself not a beginner, so perhaps I see it from that perspective.
Some additional thoughts.
Ultimately we change hue, saturation and lightness values of an area of pixels, correct? The end result, unless printed will always be based on emitted light, as long as its seen on a digital device. Only in the analog world, when we print something on paper for example we will truly change how color that our brain registers is created, by reflecting and absorbing light. So in the digital space, we always work with light emitted from the device. Therefore we can only simulate or fake the analog world. And we do this by effecting hue, saturation and lightness values. Since its a digital device, these perceived changes in Hue, Saturation and lightness of pixels will be created by varying degree of intensity of the light of the red, green or blue light coming out of the monitor. So how do we affect, hue, sat and lightness in resolve. There are many ways. From adding the opposite colors on the color wheels for example we can get subtractive primaries. By using something curves in only Y or lightness mode we can affect only lightness. If we wanted color, we can deactivate that part of the curves. We can also composite our nodes to use any number of blend modes, light lightness or color to limit the effect of any node. We can use HSL curves in any of their many modes to attack specific values. We can also use the Color Warper which will target specific range of colors and allows for individual change of Hue, Saturation or lightness of that area. Quick and easy, and automated.
The RGB Mixer palette lets you remix different amounts of image data from one channel to another, and has a wide variety of creative and utilitarian uses. Furthermore, the RGB Mixer can be used either to remix the color channels, or to add different proportions of each color channel into a monochrome image. With the “Preserve Luminance” checkbox turned on, any channel adjustment you make is prevented from altering the luma of the image by automatically raising or lowering the other two channels to compensate.
Much of this can be automated in many different ways. From power grades to various presets and even macros.
