Flash Photography Tutorial
This series of videos is designed to help off-camera flash beginners quickly advance to lighting with purpose. First, this series assumes you have an understanding of the exposure triangle, and are capable of controlling your camera in Manual mode. While it's possible to use flash with semi-automatic modes, I think it's a requirement to understand lighting in manual mode if you want to take control of all aspects of your images. This series is broken down into short, easy-to-digest lessons that progress you from balancing a single light, to using multiple lights outdoors to drive home the story in your image.
This video is designed to build a fundamental understanding of white balance and color temperature. It starts by introducing white balance and how to identify the color temperature of a scene. It then progresses into how to implement flash which is daylight balanced and gel the flash so it matches with any ambient color temperature. From there it goes over recommended gel systems for speedlights and monolights alike, highlighting gel products from Rosco, Magmod, and Flashgels.com.
Candlelight : 2700K
Tungsten : 3200K
Daylight : 5500K
Cloudy : 6300K
Shade : 7000K+
The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of a color comparable to that of the light source. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature is meaningful only for light sources that do in fact correspond somewhat closely to the radiation of some black body, i.e., those on a line from reddish/orange via yellow and more or less white to blueish white; it does not make sense to speak of the color temperature of, e.g., a green or a purple light. Color temperature is conventionally expressed in kelvin, using the symbol K, a unit of measure for absolute temperature.

Robert Hall: you are one of the best instructors out there! Thanks for making your explanations concise and easy to grasp! We appreciate you.
I was calling myself a photographer without knowing any of these info. That's why I was struggling a lot in post by using local settings in Lightroom to correct temperature on different parts of my image, and it's painful and time consuming. I really appreciate the awesome and useful video. It's full of information that is really necessary to anyone who is serious about photography.
Yeah man. You can create wonderful images without ever knowing this stuff. But this type of thing not only helps you realize your vision when your environment is less than ideal, but it's great for building consistency, decreasing post process time and therefore making more money!
Robert Hall Photography I fully agree with you! Thanks for the informative videos you make and keep it up. Looking forward to watching the following episodes about gels.
Thank you Robert. This video is very informative and easy to understand. I'm looking forward to seeing the others in the series.
An excellent demonstration of gels, thank you so much! Super easy and helpful.
One of the best, easy to understand, breakdowns of color temperature I’ve seen. Thanks!!!! This was really helpful.
I loved this video so much thank you Robert.. please keep making these videos for color temperature etc with gels, you really fueled my creativity with this!!!! Not only is it the best video on color temperature with or without flash that I've ever seen with your multiple pictures of different light color sources and what the camera settings did to those pictures, but it really gave me a new grasp point of view and perspective on color temperature and balancing lights sources that will take my photography and creativity to the next level. Thank you so much! You have a real knack for explaining things in a way that is easy to understand.
This could be like many of Hollywood's best movies start out slow but then become awesome classics as time goes on and some of the most watched movies. So don't worry about the low view count..
Thanks a lot for this useful tutorial series about white balance, one of the more important topics of photography especially when using speedlights in my case, I`m looking forward for the upcoming parts.
YOU ARE AWESOME!!! Thank you, Robert! The ONLY one who delivers!
:) thank you!
Great presentation - You have an exceptional skill for explaining concepts with clarity. Subscribed.
Thanks so much for this video! :) This is the best explanation I've come across so far - you make gels so much less scary. Thank you thank you!
Thanks for this! I’m pumped for the next two 🙂
Thanks Robert! I started following you because of your previous color correction video. Seeing this makes me happy and looking forward to the next two videos. I’ve been shooting with color correction gels a bit and what a difference they make.
Very clear explanation, can't wait for the next video for this series
One of the best gel explanation in CZcams for sure!!!! Keep doing it like that 💪🏽🙌🏽🎉
I agree!
This was, by far, the best video I've seen on this subject. Thanks Robert!
That's so encouraging to hear, thank you!
Thank you sooo much! For the first time I'm going to delve into using gels, you inspired me! Thank you!
This is gold. Understood all this stuff about gel and colour balance. Makes sense.
BEST Explanation of ALL videos. thank you.
Thank you for this! We had a discussion a few days ago on a photography FB group on this exact topic, so this video will confirm my point.
Just by chance i stumbled over one of tour videos with gels outside and immediatly felt it was the next step for me to learn om my road to master this art of ours and today i got them so this serie of videos was really helpfull thank you !!!
Great video. Looking forward to see how you tackle fluro. It does my head in a bit. 🤪
This video is excellent. Great explanation. Massive thanks!
Great series so far. Looking forward to the advanced gels tutorials.
There is still a 4th coming. But 2 follow up videos on gels are linked in the description.
Thanks, really useful and nicely explained info. looking forward for the next two videos.
Thanks so much, ill have them both up in the following weeks
Thank you so much for mentioning flashgels.com- I've been looking for the longest time for pre-cut gels for my ad600 and ad200!
No problem. Yeah he's the only one in the biz doing it. What's nice is it's all the same gels across his Godox products too so it's very consistent if you use different types of lights.
You the BEST Rob. Really appreciate. Very informative presentation👐🏽👏🏽💪
Excellent, concise video. Thank you!
This was very informative. Thank you
Thank you so much. Informative video in very easy way
Excellent video. Thank you.
Great video! This is something I deal with daily in my real estate photography. Outdoor light flooding in the window combined with the light from incandescent bulbs in the interior fixtures.
Real estate has gotta be so rough. I can only imagine the overcast color coming in from outside combined with lights of all sorts of colors and tints. Do you find that people tend to have consistent color lighting throughout their homes or is that often screwed up?
@@robhallphoto I would say 90% of the homes I shoot have mixed lighting not to mention all the color casts you will get from painted walls or certain types of flooring. A lot of photographers like to turn off the inside lights to battle the mixed lighting but I feel that looks odd. When you go to look at a home to potentially buy you don't walk through the house with all the lights turned off! So I tend to adjust my shutter speeds to minimize ambient light and then use my AD200s to bounce light off the ceilings which are usually white in most homes to get the most accurate color. I just feel using flash in real estate looks so much better than ambient only or HDR.
Look at Rich Baum's channel on CZcams. He uses flash and ambient blended light for real estate. Nathan Cool Pro also very good. Bit of post production involved but it works great.
Very informative. Thank you 👍🏻
I love you dude, really2 love you, you made it all simple and easy to understand. Thank you so much!
Excellent explanation! Thank you very much! I look forward to parts 2 and 3!
They are linked in the description ("Matching Fluorescent Lights with color correction gels" and "Inverse Color Effects with Color Correction Gels"
Just getting into all this and this presentation helped me a lot.
Its hard to get your head around at first but if you persevere it will all click the key is to practice. I set up a fluffy toy in the kitchen got some CTO & CTB and just cracked on with the help of you tubers like this. I set up my pixapro softbox/beauty dish with my Yongnou speedlight (not HSS) cut out some squared to cover the flash and then changed my WB to 2500 Kelvin and just dialled in settings that I felt happy with. It was fun to see how all this worked and I can see the potential for more creative photography once I purchase a decent flash.
But for now Im still in the practice mode and getting it all into my brain.
. . . "gels are propably the most underused tools in photography" -- very true. that´s because noone really knows when and how to use them - including myself -). I´d never thought about using them (talking about the corrections filters) because I thought I could fix it in post. Turned out to be quite difficult, so thank you for this series on videos you made on the topic. I´m glad you produce all this content on Godox products -- without it a lot of us Godox users would be kind of left hanging in the air. There isn´t much coming from the company itself, and the other channels I´ve found so far dealing with Godox aren´t as consistent and well done as yours. So thanks again! Greetings from Germany, Heiko.
Thank you. This is the best explaination of how gels are used to the ordinary person like me to understand.
Nice video! I wait for the other two videos! This subject is so interesting for me ♥ love it! Sorry about my bad english, i speak spanish.
Thank you very much, your English is great!
Thanks! This was a great video.
Perfect! Thank you! 👍🏻
Great video... You should mention the color meter built into almost all digital cameras, PRE white balance! In fact, use of PRE white balance with a grey or white card would make for an excellent stand alone video. Cheers!
I spent 40 years developing instructional materials on technical topics. Congratulations! This was clear and audience-centric. My next step would be to follow it up with a workshop in which people apply what they learned and get feedback on their work. You are a great communicator. If you have ever thought about hosting a workshop I have two words of advice, "Do it."
Man thank you so much.. this is a gold knowledge!
No problem, glad you found it helpful!
thanks for all your videos !!! Cannot wait longer for numbers 2 and 3...:-))
Olivier
Excellent basic info!
Thanks for your detailed explanation:)
Informative Robert. I have been using Rouge round Gels with the Godox H200R head which work well, the gels also have light loss printed on them too.I hope Godox improve and expand the AK-R1 Gels, but I guess it will take time.
Thanks Robert this is very informative.
Got a MagMod base kit for Xmas.
They make gelling super quick. Awesome tool to have.
Great video! Very helpful. 😁
Cheers. So are you.
Thank u this is great!
Excellent video!
Thanks!
Thank you Robert. You explain the complexity of flash photography very well. Keep producing great videos and I'll keep liking them! Any experience with the Sony flash system HVL-F60RM and the FA-WRC1M transmitter?
very use full information Thank you so much
You're very welcome.
I was following along and thinking 'how the heck...' when you rolled into the demonstration with the digital lights and the in-camera temperature adjustments to match each simulation. This video was great along with your other content, especially those that explain why you'd need a particular flash model. I plan on upgrading my Neewer 750II & TT560's to a GODOX V1 & two AD200's based on your videos & my own experience so far. Thanks for the help!
Brilliant tools
Nice , very informative
Nice explanation 🙂
nice video. very helpful. from Cape Town, South Africa
Wow. Thank you for this advanced look at gels. I’m going have to watch a few more times to understand. I thought that shooting raw made setting in-camera white balance unnecessary. I hope in future videos you can address this. Much of the time I don’t use a flash but still run into how to manage white balance. I’ve always assumed that raw was the best way to shoot.
Shooting in raw does allow you to modify color. The problem is an image with split color. If you have half of an image lit by tungsten lighting and half by daylight, theres no white balance setting that will make both colors look normal. You could use the raw image to do local adjustments like brushing to potentially make it appear one color, but that's so much excess work when tossing a gel on your flash fixes it completely and looks more natural.
Great vid.
give him billion dollars for explaining so nicely best tutor and photographer :)
Thank you!!!
And this is the best video on youtube för this
Yep, this vid the penny finally dropped for me thanks!
Great 8 Thanks very much !!
Love the videos keep it up
THanks so much!
Thank you for this easy-to-follow video. I bought the Selens gel kit from Amazon 4 years ago and used them once because the colors were horrible! 😂
Thanks - this is really helpful for some events I’ve got coming up soon. I was wondering if it’s usually ok to trust auto WB when using CTO to balance colours in the room, and then edit the WB in Lightroom if it’s needed?
Verry good video! I am looking forward to video 2 and 3. When i shoot at sunrise/sunset i need add a CTO (Full CTO) and when i shoot in the city at night a CTB (Full CTB) is this correct?
Yeh🤘🤘🤘🤘🤘 you are the number one man👍👍👍👍👍👍👍
magmods are so convenient! got myself two sets for my two speedlights, best investment so far (for accessories) :D
still looking for something similarly simple for my strobe's head... so yeah same issue as you have with your ad200 :/
Yeah nothing quick exists for the AD200 barebulb. Part of the reason I've switched to the round head.
Thank you! :)
You're very welcome
Your videos have been super helpful for figuring out how to use color corrective gels. In this video when you set your custom white balance your camera is giving you the kelvin and tint readings. I'm working with a Canon R6 and can't seem to find that info when I add an image for CWB. I'm wondering if this is a manufacturer difference or if I'm looking in the wrong place. Any idea?
This is a great video..thanks so much. Question: How do I know, when I walk into a room, what kind of light im looking at? Many times its obvious but not always.
By "type" do you mean style of bulb? You can almost associate them with periods in time or type of building. A classic church is more likely to have incandescent bulbs or potentially replacement CFL bulbs whereas an older office will likely have florescent tubes behind diffusion panels. More modern interiors are using all sorts of configurations with LEDs. I really don't know how to explain how to know other than, knowing what each of the bulbs look like.
Great video, just in time and I just bought some gels, can you or do you have a tutorial for a proper way of using/connecting xpro markii with godox tt600? or something like that as I'm new to flash and triggers. You inspired me of buying both last week.
No I've actually never had the TT600 to make a video with it. It's pretty similar to the V350 though if you want to watch that video.
Thank you for your video of Gels! Based on your video, would I have to gel all lights or just the key and fill lights? Thank you. JP
Nice video. You did a good job explaining something that I don't usually see people do. You can also check out Bobbi Lane who explains how to correct for two light sources in her book. I've always used a color meter. You can get a kenko color meter or an older minolta color meter. Sekonic makes a great one now but it is $1500 and might be a bit much for amateur photographers. Thanks again.
Yeah it seems the best present day budget option is the Illuminati. Even those older ones can be quite pricey. I really have to get something soon.
Actually when you are talking of fire, blue is the hottest area and orange the area most oxygenated, thus coolest by far, but I got it anyway. Thank you for this video series!
Blue flame is the hottest (degrees) and most cool color
Orange flame is the coldest (degrees) and most warm color.
It's the same as how colors work on the Kelvin scale.
Hey Robert. After watching your video yesterday, I started to search for gels for my V860II and AD200. Just checked Magmod website and found out their new octabox (Magbox) which you can add gels to your light inside the softbox. It looks interesting. Have you ever used this softbox? Any thoughts? I'll appreciate if you can review it.
Good job, we ll done! Have you considered a 4th video on the Illuminati light and color meter? For $299 at Adorama, it is an incredible tool for measuring color and the app will help you select the right gel. This makes color metering affordable. I use it and don’t want to miss it. Looking forward to your next videos in this series.
Yeah I checked it out at WPPI in 2018 but that was before they were available. I was actually in contact with them for a while but it dropped off before they ever started releasing them. I'll definitely check it out, I'd love to get more accurate color tests for my strobe comparisons too.
I think this is the first time that color measurements are affordable. The app has a library of most common filters. When you select some filters, the display will show you the color temperature of ambient, strobe and strobe + filter. This makes it real easy to select the right filter prior to installing it. Have fun with it.
Thanks for another great video. Does soft box or diffuser change the color temperature? If I use a large soft box over a gelled flash, is light going to maintain the color temperature?
All modifiers will warm or cool the flash a little bit, but not to the extent that it will offset your gel. At most it should deviate like 100K or so, and if it does more its due to aging of the materials or a really cheap softbox.
at 1:29 of the video you show that there will be 3 videos on using gels. Can you please update the description with the names/links for those videos? I think I found the second one, titled Flash Photography tips for using colored effect gels. Hopefully that is the one as video #2.
The penny has dropped! I barely use flash, but sometimes I have to for a voluntary organisation. I’ve always struggled getting nice skin tones with accurate background colours.... can’t wait to try a cto next time! Thank you.
What light are you using to get the blue colored background?
Can you combine a color correction with a creative on one bulb?
I see Godox has wistro mini reflector with gels for AD200..not sure if this is a new launch:)
Last month I got a Godox TT350 speedlight and I've been struggling with the white balance. If I take a picture of something dark or grey and bring the raw file into photoshop or DxO, I see that the proper white balance is around 8000k and -20 for the tint, that's a far cry from the 5500k that it's rated at. I've been getting a cool color cast when taking pictures outside when white balancing to 5500k. If I get a perfect gray or white, then the other colors end up looking warm in my factory calibrated monitor, although I guess that's how it's supposed to look like, I'm just not used to it.
@ 8:04 what did you mean when you said, you can choose the appropriate gel. It that what the B0.5 is?
You rock.
Thank you!
Excellent video. I've been using the custom white balance on my Sony A1 wrong! I've been shooting the gray card with flash turned on (gelled or naked)and using that Kevin. Sounds like the objective is to measure ambient WB and then to gel to get as close as possible to that color temp which makes sense?
You got it!
In the former way, you are getting a "middleground Kelvin". Basically the number if you were mixing light together in a bowl. Unfortunately the light doesn't mix, which results in the split color casts where either light source casts shadows.
By identifying the ambient color and gelling your flash to that temp, where either light source hits as well as cast shadows will all be the same temperature.
@@robhallphoto thanks for the response! So realistically if most of us are traveling with just full / half / quarter CTO & CTB, how close do we need to get to ambient? Within several hundred K?
Great information but is there anyway you could not put an ad in the middle of your video or at least not let it cut you off mid sentence. Your stuff is super informative and if you ever see deals on the evolve or ad200 let me know because I hate I missed that deal back in December.
Great video, thanks for the info. I am going to ask a silly question? If going higher in temperature is cooler and low is warmer, when then it LR the temp is opposite as you go higher it is warmer?
Think of it like light color is the outdoor air and post production is a heating/cooling system. Proper white balance is just like a comfortable room. If the air is very cold, the furnace has to heat (add warmth) to even it out. And if the air is very warm the AC has to cool it to even out.
The act of choosing your white balance (in camera or in post) is the method of compensating for the color of light. So in order to make blue light (let's say 9000k) white, you have to add lots of yellow. And to make yellow light white you have to add lots of blue. That's why it's represented in the inverse manner.
Thank you!!!@@robhallphoto
I noticed your video on 2:47 had a warm tone instead of a blue cooler tone. Are they opposite on your camera?
Great video Robert! Quick question, are there more gels available for the AK-R1 H200R round head
Not currently. They said they'd be adding them but yet to make any announcements. I've been using the kits from flashgels.com cause they are cut perfectly and accurate.
@@robhallphoto Thanks Robert, so if I understand correctly, YES but with third party gels from flashgels.com and not from Godox. If so, fine by me! I'll check flashgels.com
HI Rob, ask a silly question when using the kelvin in my camera the Kelvin reading is opposite the above graph, EG, 2500K on the back of the camera is blue:-(
That's because a camera is compensating for the color of light. 7000k is a blue light, meaning a camera needs it's 7000k to apply a lot of yellow to offset what is naturally occurring.
I've been looking for an easy way to get the Godox AD-B2 with a single bulb or two bulbs. Have you found any solutions yet? P.S. Your reviews have been a huge impact on my buying decisions. I try to use your affiliate links but I can't always do that with discounts here and there. Please keep up the great work and I hope your sponsors know how much impact you have.
Easy, don't know that there is one. But the most complete way is definitely the flashgels.com ones since they are perfectly cut to cover the barebulb 100%
Oh, I see what you're saying. Use the AD200 barebulb gels. Since there are two bulbs in the AD-B2 it'll be $100 for the two kits. Kind of more than I'd like to spend on gels. I might have to buy full sheet's and get the inside of the modifiers. :-/
I wish Godox had a solution for this. Or if someone came up with an aftermarket solution.
Thanks though.
Hey, you mention not to put gels over exposed flash tubes. How then do you mount the gels for the AD200's bare bulb?
There is glass covering the flash tube on the AD200 barebulb, so nothing makes contact with the tube when you gel the barebulb.
@@robhallphoto Perfect, thanks for the reply!
Awesome as always man! Just to tease: why didn't you mention the color setup you actually use in the video as an example? I'm assuming your room isn't actually blue to the eye... 😉
That will get discussed in more advanced video once I introduce effect gels and intentionally shifting color temperatures. My setup is 4600K on the key light, blue on the background (at 6500k temp to make it REALLY blue) and 3300k hairlight, with the camera at 4700k.
@@robhallphoto gotcha. Cool (or warm, or both... Hehe, you got me)!
For the round head I just cut a square piece from a Lee gel sheet and hold it on with an empty magnetic gel holder. There's no real need for them to be round is there? I can buy a 20x24" sheet of gel for not much more that just one of these round gels.
No need at all. The one problem I've found is the magnets don't have as secure of a connection when there is a gel in between them so the mods slide off a lot easier (especially when stacking multiple). For one it seems ok.
You say not to put gels on bare bulbs but I’ve seen you put gels directly on the AD200Pro ... can you clarify when it’s ok to apply directly to a bulb and when it’s not? Thanks.
In the video I say do not put gels on a flash tube. The flash tube (helical shaped bulb) of the AD200 barebulb is covered by glass, which is safe to put gels on since the glass does not get hot enough to burn a heat resistant gel. But an exposed flash tube (like a PCB Einstein if you remove the diffusion cover) should not be gelled or even touched. Just the oils from your hand can cause the bulb to explode once it gets hot.
@@robhallphoto Ahh ok. I don't think I've ever used strobes that have truly exposed bulbs, which is why I was a bit confused. Thanks for clearing that up!
