Why you should STOP using CRI & TLCI

Did you know that CRI & TLCI were not designed for filmmakers to measure the spectral quality of their lights? The ACADEMY deemed them as “inappropriate to describe lighting for digital cinema cameras”. So why are we still using them? And what’s the best option out there that’s designed specifically for us to measure the spectral quality of our LED lights? Find out in this episode

@@ysoltys Im trying out the Zolar Lights right now, they are really nice!

[@666size666]

@@ysoltys Andrew Locke of Gaffer and Gear has a great review of their light the 30c.

[@curtisjudd]

Nice coverage of color accuracy for lighting instruments in the context of video 👍 SSI is a useful metric, but, like you mentioned, I like to go beyond just looking at the final summary score and look at the spectral power distribution graph to understand where any particular light varies from a standard reference.

[@THEDPJOURNEY]

Absolutely, I personally look at SSI first to get a general idea on how well it performs, if it’s below 90, which is usually the case with 90% of the lights out there, I know for a fact it’s the blue colour spectrum range that’s causing that, since the reds are mostly ok nowadays. But I still have a look at the TM 30 to get a more specific snapshot of the Light’s strengths and weaknesses

[@Photographicelements]

In case you’re wondering, I’m the one who keeps asking B&H for the SSI rating for all their LED lights. Thanks for this video! I spent my whole life really seeing light and color. Thank God, fluorescents are no longer on sets. Look forward to the next pro video!

[@THEDPJOURNEY]

Really glad you’re asking them! I also just got a new request for a review of a light, and surprisingly they didn’t have any SSI scores for their lights. Let’s all work together to change this

[@phpn99]

You should have talked about the concept of metamerism, and SPD multiplication, which this is all about. Alongside SSI, the purpose of the ACES system is to minimize the observer effect when it comes to cinema production, so the "observer" is normalized as much as feasible. In lab work, the chosen light source is a deuterium arc lamp, which has a continuous spectrum between 200 and 450 nanometers (so, mostly in the UV range). Old-time cinematographers know that the best light source for colour balancing is the energy-hungry Tungsten light, because it has a smooth spectrum that easily bears modulation via coloured filters. Another less-known fact, is that exposure meters are usually only reliable when used with a tungsten source, for the same reason. When used with an LED, HMI or Xenon flash source it's important to calibrate your meter by measuring a good quality 18% grey card and dialing in the exposure error ; often close to 0.5 stop.

[@THEDPJOURNEY]

I wish I talked about so many other things actually. Was just replying to another comment about how had this was to distill such complex topic into a digestible video any average person would find informative and not too technical. I have DP friends who couldn't finish it because it's too technical for them... imaging? Thanks for your support ;)

[@TDCIYB77]

I would add the GOAT Curtis Judd to that list of Creators, IIRC he also uses SSI and also just reviewed the new Aperture Amaran S lights praising them for the light quality. Also: So great to see the notification that you made a new video!

[@THEDPJOURNEY]

Oh you're right!!! Curtis! Should've mentioned him for sure. But let's not make this the exception of 2-3 KZbinrs, but more like the Rule from now on. Thanks for watching, it's good to be back. More to come very soon

[@NeilSnapePhotography]

Coming from a consultants point of view, this is exactly what marketing doesn't want. But I do, just to know where a product stands in its ability to make the most of the colour needed. Excellent video and you did a great job of explaing in simple terms how this information can be used.

[@THEDPJOURNEY]

Much appreciated! Really happy this could be an eye opener for everyone especially lighting brands

[@tomdchi12]

I strongly agree about the value of SSI versus previous systems! (But one small critique of your overall excellent explanation - around 8m 20s - because these graphs are normalized for their respective peaks, simply overlaying them like that exaggerates the differences or similarities. Those differences across the visible spectrum are exactly the important issue, but the difference in the "area under the curve" isn't comparable in that straightforward of a way. That said, this minor point doesn't take away from the fact that you've laid out the problems and why SSI is so important a solution!)

[@THEDPJOURNEY]

You know I've been buried deep in that rabbit hole for the last month trying to find the best way to distill and simplify such incredibly technical topic to make it easy enough for the average filmmaker to watch... believe me, it's not easy, hahah I had to cut off so much fat from this not to be too sciencey to scare peoapl off. So really thank you for pointing this out, but all this was more like taking the creative freedom to simplify it without butchering it on a technical level. HOpe that makes sense.

[@tomdchi12]

@@THEDPJOURNEY That absolutely makes sense! The physicist Richard Feynman said the best way to learn something is to imagine teaching it to someone. I've imagined it so I very much understand how much more there is. But unlike my imagination, you actually put together a very good explanation!

[@timkang1980]

The exaggeration due to the overlay is honestly very helpful. It's more about understanding the metric score, not the other way around. For example, if I have a score of 73 for daylight diodes vs real 5600K sunlight I measured outside, then I can see what part of the spectrum contributes most to the 23% difference (the UVA / violet region). That is crucial to know since the contribution of that portion is very subtle to most color rendering.... it's important, but subtle, and that's why a score of 73 in daylight is actually not as bad as it sounds.

After a very long time came upon a video this good, Thank you for such an easy explanation I work with galleries and photograph art/sculptures etc and I was using a color checker as well but I was seeing these problems but couldn't identify the actual problem plus I saw a shift while using regular strobes and battery powered ones. Also you were right about the sensors, even after creating a custom profile and keeping correct WB I was seeing a shift in reds, whatever strobe I used and then realised my camera sensor shifts the reds towards magenta so I have to manually adjust that before I start shooting.

Thanks for the video. So glad to see you back here on youtube.

Can we just reduce the saturation of the blue channel in a specific luminance range?

[@THEDPJOURNEY]

Yeah I know the feeling. Some time ago when they released SSI, I went back and realised all the lights I had with no exception were better in Tungsten than in daylight. So I was trying to shoot in Tungsten as much as I can. There isn’t much of a solution I’m aware of apart from maybe using some gels. But that defies the purpose of bicolour after all

Excellent video. QUESTION: I am trying to improve my painting studio lighting. Hard to find consistent/accurate info... I believe I want a 'full spectrum' bulb but most people say that 5000k and full spectrum are the same. I believe that a spectrometer will capture the difference between 5000k and full spectrum (but I am not sure if this is true). 5000k and Daylight may look the same to our human eye but they way that color is rendered can be different. Is this correct? What is the best bulb to accurately capture color on a canvas? Any suggestions would be greatly appreciated!!

[@THEDPJOURNEY]

Color temperature and being full spectrum are not connected. You can have full spectrum in both 3200 and 5500 Usually daylight colour is harder to get in full spectrum, so the cheapest way is to use the good old tungsten bulb. Or invest in a high SSI video light like the Zolar.

The Neewer 1200 RGB panels also state an SSI (D32) of 85 which is a great to see. I wonder if companies will now only include one of two (daylight or tungsten) because the other might be really low.

[@THEDPJOURNEY]

Interesting, usually the D55 is the lower one, also usually in the mid 70's, so I guess that might be a reason Neewer didn't mention it. Gotta test it before assuming

Quasar Science was the one that started posting SSI and encouraging companies to do so in 2019. I know because that was me. 🤷🏻‍♂️

[@timkang1980]

​@@THEDPJOURNEY I started campaigning for this in 2018 internally, and then have had it as a main goal for the ASC lighting committee. A big issue is misunderstanding by the industry, as well as seeing a C score for daylight and thinking it's bad (when it's not).

[@THEDPJOURNEY]

Yeah that’s what I was thinking about the mid 70s score for daylight. They’re scared to show such scores and people would think it’s pretty bad. But now I can see scores coming up to mid85s and 90s, so I guess we should see more of SSI reveal parties LOL

[@RoyaltyInTraining.]

I don't trust anything but a full datasheet with the light's spectrum. The fact that almost no brand provides that makes them all look scummy.

3 chip 2/3" cameras are not "older by design". They are there to run alongside single chip cameras for ENG usage. They follow different design parts. Specifically for television and sports. Reality TV. You will always have 2/3" sensor ENG cameras. They are NOT designed to compete in the cinema space. They are not an older technology, but a different format, and are actively updated just as frequently as your cinema cameras. They are designed concurrently with single chip cinema cameras.

[@THEDPJOURNEY]

I think you misunderstood "Older" with "Antiquated" or "Obsolete", I didn't say or implied any of that. Also I never said single chip is replacing them as they're "New". 3 Chip are older technology if you consider the time these were put to use in broadcast and Single chip were put to use in Cinema. Hope that clarifies any confusion

[@skymakai]

Wow... so even the Aputure 600d with an SSI of 72 isn't "Good" by SSI measurements? iFootage is such an innovative company. I'm curious to see what they develop in the future.

[@THEDPJOURNEY]

Yeah I was impressed when i saw their scores!

[@timkang1980]

72 is good for daylight.

[@THEDPJOURNEY]

It’s not the best for sure, but you need to look at the SPD graph and see what caused it, the place where you have the worst misalignment basically will tell you which Coolors suffer the most

[@THEDPJOURNEY]

Another tip is, as much as I can I try to shoot in tungsten mode since it offers the better SSI score. So if you’re shooting anything in the dark for example, set your lights at Tungsten (provided tungsten’s SSI is higher than Daylight’s that is of course)

[@jasonzhang6631]

SSI is the way!

[@THEDPJOURNEY]

Yes… this is the way 😉

[@_burd]

I'm wondering are there white papers out there with numbers for the likes of ARRI Tungsten and Daylight fixtures, Other brands like Lekos or Dedos, multi-diode LED panels, studio flourescent arrays like Kino-flo etc... even against practicals like average household flourescent/incandescents. Seeing how different technologies compare in context would also be interesting. Then there are the ratings once modified, but that gets very complicated xD

[@THEDPJOURNEY]

White papers are more reserved for scientific discoveries I'd say rather than technical measurements for exisitng lights. I was surprised that ARRI didnt have much SSI info about their lights actually. But again, if you have a spectrometer, it's pretty easy to just measure them. TOTALLY AGREE I just hope to find a database out there with all metrics of all those lights.

[@666size666]

I find that I have better working rapport and respect for a DP who cut their teeth in the industry as a gaffer before becoming a DP. A film set isn't a good place to teach lighting to your "boss." Might I also add that if anyone has said "did you notice the inconsistency of the SSI color score of those 2 lights in that last scene?" then the movie has much more than the lighting wrong with it.

[@THEDPJOURNEY]

People don’t notice inconsistencies in SSI in a scene, gaffers and DPs notice those inconsistencies and that’s when it’s hard to fix on set or in post if you’re mixing them in one scene. As mentioned I learned that the hard way on set. After all, SSI just like other metrics is not just a number, it’s a graph DPs need to understand to be able to know the strength and weakness

Unless you’re using this light to light you workspace or your home, not your film production, then TM30 is the wrong metric to use

[@timkang1980]

​@@THEDPJOURNEY That is not true. There actually is a pretty strong correlation with the hue vector graph and how I've seen cameras work. Everything else is somewhat meaningless in the spec for photography. There is no perfect metric, just different tools for different uses.

@@timkang1980 Check the white paper I referred to in the Description that shows what I mean. Our eyes are not like camera sensors, yes they're similar in some aspects of vision, that's why I'm saying those scores can give you a hint, but not an accurate reading you judge the light by. Please watch the full video to understand the full picture. I explained it mostly there... you can find the missing parts online. Thanks again

[@timkang1980]

@@THEDPJOURNEY I know the white paper, and I'm one of the main folks defining this for the industry. I have a firm grasp of all the color science behind both. the observer model used for TM30 is CIE 1964 10 degreee. Cameras are TRYING to do CIE 1931, but regardless of these forest view differences between camera and the CIE model (remember, it's not actually the human eye, but this theoretical camera), I've found over time and doing a lot of tests that the Hue vector graph actually tends to track pretty well with the color distortions you'd see in camera.

[@THEDPJOURNEY]

But we’re going back to having an observer with your method in TM30, which kinda makes the test subjective to that theoretical observer which does not represent every observer in our world since we have infinite amounts. While SSI takes that out of the equation. You compare the light to what it’s pretending to be, sun or bulb. It’s exactly like what happened with the kilogram, the reference was an actual weight (Le grand K) that was used to calibrate all kilos in the world, but that kept on changing weight due to physics basically, so they ended up Turing the reference into a qualitative equation… hence the sun and bulb became plank numbers, don’t use a reference, use math. And that’s SSI

I really wait for you review and oppinion on 2 recent hot selling cameras: Canon R8 and Pana S5 MK2 and how they compare. I think that the camera manifacturers must send you some demo models, but they dont have balls, because they are afraid from the truth right?

[@THEDPJOURNEY]

That’s exactly what I think happened with Panasonic. Since my last review about the GH6 and they’re not answering my requests for test units. Canon mainly send to their ambassadors like Peter McKinnon I believe, I don’t think brands can handle the truth! LOL

@@THEDPJOURNEY I respect people who are honest and can prove their point of view! I do the same, and often companies attack me as well, because they are idiots. Instead of listen and change they shouthing against us. Again, respect for the great work and honesty!

SO does this mean my CRI 80 light bulbs from Lowe's may actually be pretty good??? lol

Please, it's just a small favor! It would be great if you could subtitle your videos, so that your large global community can use the translator of the platform, based on a correct subtitling and not the disaster that makes the automatic subtitling with its lousy translator. They give us very valuable information that requires a high level of knowledge and a lot of attention. With very technical concepts and others, it is important that the subtitle has the correct term for all of us in the rest of the world. I hope you can take it into consideration.

[@THEDPJOURNEY]

Hey Harold, thank you for the comment and the request. You can actually get closed captions now if you press on the CC button at the lower right corner of the video. Let me know if that works

[@capodicasa]

@@THEDPJOURNEY Yes, the subtitles are there, in the CC button, but they are automatically generated, which means that it is not entirely accurate, according to what you say, sometimes, it can also leave out a great sentence, in which the information they give, can be very important. It all gets worse, when you try to translate into another language, that being a printed subtitle, it all becomes an informational chaos. I wish they could transcribe the subtitles, because it keeps the information very technical and the translation is 100% accurate and clear. Although I can also understand that it is a lot of work to subtitle the videos.....
