Great video! I'd keep the Aputure. It may not be "industry standard" but your test demonstrates it currently functions better, which'll save time. When you save time, you save money. You made a great point at the end too. Owning every piece of kit possible isn't a sustainable business model. It really only makes sense to own the gear you'll use on a regular basis. It's worth investing in the essentials, especially if you're green so you can practice and hone skills in preparation for paid gigs. But for stuff you only use a few times a year, utilize rental houses and factor it into your rate. That's my two cents anyway haha.
Yupp! I agree
Yeah, crazy the difference like it’s super noticeable it’s not a subtle difference. Thanks for doing that. It’s always interesting.
I hope you’re doing well, my friend, hoping that this year is a great year for you
Thanks Randall, same to you
I feel like as long as you know the limitations of the Cream Source, depending on the project it can help achieve a "look" in camera, whether more prominent and achieving a Matrix vibe, or more likely, again, using it in the background. I know when I'm grading my footage I tend to separate skin tones and warmer colors from the rest of the image, specifically to push the greens and blues a little more green, while still preserving healthy skin tones. Having the Cream Source in the background and usinging a Nova or a COB light as a key would already push that look into the footage.
great insights!
Happy New Years Justin
Happy New Year 🙌🏼
We got 4 Nova 600c and 2 Nova 300c. Love them!
Interesting video. Thank you! Id love to have seen what would happen if you did basic white balance correction on the image in davinci. How much the background would have shifted to magenta.
Great video as always Justin!
Even though the Cream is 15 years old and has really been used on big sets, I doubt that it was used as a key light, or in any situation where color rendition matters (they would've used Tungsten fixtures or maybe an Arri SkyPanel at the time for that). Considering the extremely strong green/yellow cast, they were probably used to light green screens, or as an ''fx'' light/fluorescent ''enhancer'' or something. Maybe to shoot some disturbing scenes, SAW style when the goal is to disgust the audience lol but I've seen street lights with better color rendition! The output is insane though :P
HAPPY NEW YEAR to DTP!
😆 Happy New Year
Is there a correction gel that could help that color cast and still have decent output?
Was thinking the same. Considering the output it's worth to just have a few sheets of minus green gels and some CTOs as well when needed.
for sure for sure, maybe this would be an interesting follow up video.
@@JustinPhillip Would definitely be interested in seeing the results.
No, that's actually not possible (except maybe theoretically with a very precisely engineered gel that would cut maybe 2-3 stops of light in the first place.)
This is because R9, the part of the red spectrum in the tests that's very important for skintones, is very, very low. Gels can only cut out parts of the visible spectrum, and since that color is nearly absent from the light, gels could not add that part of the spectrum back.
I mean, you could try some minus green, and maybe 1/8 CTB to get it closer to 5600K. But it still won't look right on human faces or anything red.
I like creamsource as a brand, but I never got any chance to have some discount, or proper partnership with them. And seeing the results, I am impressed by this Aputure. I got a few 120Ds and I never was a big fan. My LED Kino is something else, I love it!
Yea Kino is on the same level as the big boys
Isn’t it all about SSI?
That’s why the Amaran s series is so great. Even though the build quality is not necessarily professional grade and built in v mounts are missing, the SSI scores are crazy high and impressive
Same for the Ifootage anglerfish series, and the zolar panel lights
SSI is spectral similarity. Thats just a comparison to other lights.
This video is confusing to me. The images made sense to me in that the tint of the creamsource light seemed to be way over toward green, which I thought matched the CRI charts where that light was way down on red (and also the lavender and magenta color bars). But then in the RGB parade, it seemed to be showing overly red... Confusing.
I'm in the process of down scaling as well. While I have a lot of grip gear, I find that I'm really only using my 4x4 mat lights, the two Nanlite FS-300s for lighting through windows and some of the Zhiyun or Nanlite 60s's for fill and hair lights. I'm not really bringing all the big heavy panels or my super heavy Aputure COB lights these days if I can help it. Occasional I'll bring my two foot tube light kit, but it depends on the gig. If I need a 600 or a 1200, that's a rent now-a-days.
Yup. 100% where im at as well
Random question from an internet stranger but-
What grip gear do you have/recommend for a stripped down yet functional kit?
I've never seen a cream source light lol but I had the first aputure when they came out Iove their original form factor.
Did you set a custom white balance in camera for each light? I just can’t believe the difference.
Yes they were both balanced to the color meter
Did you try to color correct it? How easy was it to correct in post?
you could shift it back in post, but it would definitely take some work with the qualifier and the curve. But harder if you're not shooting raw of course.
The R9 is the worst I've ever seen!! Still def worth keeping it just to use it as light through a window. Crazy output!!! As per other comments, maybe a correction gel? I have also just acquired a used C800 from Gaffer and Gear and I'm crazily and obsessively checking every light source I see.
It is true about the R9. The first time i took the reading i was so shocked i thought it was an accident 😅
I just can’t believe the difference. I was expecting almost no difference after white balance but the result is horrendous. Did you white balance the camera to the actual output?
Yupp. Both were measured correctly with the meter, down to tint correction
How about retesting with the exact same diffusion?
for sure, but my issue is the initial readings that i show in the video, those were taken without any modifiers. So the numbers are poor right out the gate. Thats my main concern
how did u make sure the Aputure 600p was perfect with your color meter ?
I matched it to the creamsource with the meter.
have u used aputures Amaran flex lights ? if so are they more useful than a Aputure 600 nova? I like the nova for skin tones but I rather have the new intellytech mega rgb for that use because they are lighter @@JustinPhillip
Is footage recorded with bad CRI able to be saved in post with color correction?
Yes, but with much more practice & patience. And depending on how awful the colors out of the led unit are, sometimes skin tones will never be 100% accurate
Maybe. But usually, unlikely.
I think you have on 2x zoom in vector scope
Yes
@@JustinPhillip yea that’s why the colours exceed the boundaries of the scope. If it truly exceeded the scopes like that the image would’ve been much much much worse.
I’m a pro colorist. I’ve gone crazy like that lol.
but can't this be fixed with color correction .
Yes
14:00 I think you just broke my GAS. I don't have room for this shit and I can't afford to get robbed!!! JOB A JOB FIRST!!! RENT EQUIPMENT ELSE THEY WON'T HAVE CUSTOMERS AND YOU WONT BE ABLE TO RENT IT!!!
😆💯
All you have to is add color correction gel to the light. Problem solved.
Im not so sure about that, but could be a fun follow up video. See if tint correction would fix bad color rendering…
@@JustinPhillipwould love to see that vid!
@@JustinPhillip - Give it a shot. Let’s say 10, 15 or 20 Red or Magenta?
