UPDATE: 3/4 CTO (285) is now the closest option available for a true 5600k daylight to tungsten conversion, converting 5600k to 3300K. There is also a 3/4 CTB (281) that converts 3200k to 5000k.

Hi Dave! I have a question and I would really appreciate it if you could clarify it for me. If I am photographing in a very large indoor environment in which I must balance the ambient light with the flash light, but I have an extreme situation of lamps with lights at 2800 Kelvin and another at 7000 Kelvin, is it possible to balance these extremes using the CTO or CTB? Thank you for your attention! Thank you very much
Hi Alex, great question! For situations like this, Lee filters has a fantastic tool you can use. They have a color temperature/mired shift calculator where you can input your source CT and your desired CT and it will tell you the specific gel (or combination of gels) that you will need to balance it. leefilters.com/lighting/colour-temperature-calculator/ Looks like the closest to a 7000->5600k conversion is: 809 Zircon Warm Amber 8 But 1/8 CTO and 1/8 CT Straw will both get you very close. For the 2800k source, 201 Full C.T. Blue + 203 Quarter C.T. Blue combined will get you the closest to 5600k. Have a play! It's a great tool!
ok one quick question... can we use these gel for improving CRI of household lights??? can we use household lights which has CRI value of 70-80 and put on these gels to compensate the colors?
Great question, but unfortunately no, adding a gel won’t change a lights CRI. The colour rendering is a feature of the light fixture itself. Gels can shift a lights colour temperature, or change its colour, but it won’t impact the CRI.
but isnt it low CRI means absence of some color? @@CreativePathFilms gosh I really wanted to try this out... but unfortunately I don't have a light meter to measure it... can you please do a video or at least try it without shooting with some household light having low cri and let me know about the results... with gels and with a lightest red bounce board... please?? 🙏
@@arun_kumar0 Low CRI can be an absence of a part of the colour spectrum, or a spike in the spectrum giving an unwanted cast. And those things are often inconsistent in cheaper fixtures, from fixture to fixture. Whilst theoretically you could attempt to correct a spike in say, green, for example with a magenta correction gel, you would need a spectrometer (which we don't have at this time, so I cant make this experiment for you) to measure that specific fixture and try and find the gel to compensate. Even if you went through that exercise, I would expect an only slight improvement. I would think the cost of the gels would also probably exceed the cost of a more colour accurate household lighting fixture.
Thank you for the video! I am using a 5600k key light (Amaran 100D) and want to warm it into the Tungsten range. This pack looks like awesome value but it's very confusing how the Lee filters base daylight at 6500k and there doesn't seem to be much discussion about this on any of the sites on which they are sold. If it wasn't for this video, I never would have noticed. What are the problems faced by using these gels on a 5600k light? Does it simply mean you can not determine the exact colour temperature without a light meter? If I had to get very close to 3200k, would I be able to do this using this kit? Is it much of an issue at all for a content creator? I am using the 100D + gels as a key with an assortment of Aputure/Amaran RGB's as fill, rim and background. It would be good to be able to easily match the temperature of the key+gels, but it is probably something I can eyeball without any issue really. Should I just get this kit and stop worrying about it? Thanks again! :)
Hey Jesse, Thanks for stopping by and for writing such a detailed question - you got my brain cooking and I love it (you've potentially inspired another video!) It's getting late here in AUS so I'm going to probably look over this and add to my answers in the morning. In short, if you use full CTO on a 5600k light, with a white balance of 3200k, your results will be warmer and your skin tones will look off, as they did in the video. We won't be able to scientifically measure the kelvin change without a spectrometer like the sekonic C-800, which is out of the budget of most content creators - hell, anyone short of a gaffer usually. There are three solutions I can think of: 1. You can just roll with it and have a slightly warmer look - not my favourite. 2. You can set your WB to 3000k-ish and balance your RGB panels accordingly so they have the same base CCT - Still not my favourite. 3. If you cant get Lee 626, which is designed for this specific conversion, you can solve it with math - by working it out using a mired shift. I may do a video on this but for now I've saved you the trouble, the closest you can get with stock CTO gels, is to gel your 5600k lights with a combination of 1/2 CTO (205) + 1/8 CTO (223) which will get you really, really close. The difference is around 1 mired shift. (I will double check this in the morning!) Now you can't get 1/8 CTO in the Master location pack, but you can either buy it by the sheet, or it comes with the Lee Daylight to Tungsten pack (I've popped a link in the description). If you were only buying it for the CTO gels, that's what I'd get instead. If you wanted all the other gels, you could consider buying both packs, or buy a sheet of 223. Hope that helps. I'll check back in, in the morning to answer any questions you have.
@@CreativePathFilms wow amazing response! Thanks for taking the time to write it before bedtime. I'm also in Australia. I am actually wanting to keep a warm tint mainly because I live high in the Blue Mountains and could use some help when it comes to goldening up my skin tones! When you calculate the end colour temperature after using gels, is it straight subtraction? For example, the Lee Daylight to Tungsten says that the: 1/8 CTO is 6500 to 5500k 1/4 CTO is 6500 to 4600K So there seems to be some sort of ratio or is subtraction close enough? The 626 gels seem to quite scarce. Perhaps it would be best to just get the Rosco set which has CTO, 1/4 CTO, 1/2 CTO and 1/8 CTO. It's just more expensive and you only get one of each instead of 2 as you do with the Lee set. Thanks again!
@@CreativePathFilms I should also point out that a big reason I am wanting to shift my keylight to tungsten is so I can film at night under a more reddish colour temp in order to help my sleep cycle, so it isn't simply a matter of hacking skin tones in post.
