Recently I shot a short on film. I shot super 35. Because of the space LEDs were a good option however because we were on film I was unable to do any tests. I wanted to shoot 2 or 3 perf so I could have performed the tests but the director was adamant about super 35. I used mostly sky panels and Light Mattes but was just curious about flaws or issues if any, or stuff to watch out for shooting film beyond the normal stuff. with the new LED systems as most of the time when I do still shoot film I haven't used LEDs. The new firmware on the panel helps with the flicker issue a lot too.

Hey, I recently came across an article about experience with LED lights while shooting on film. It is actually quite tricky. You might know Spectral power distribution graph. They show which wavelengths are in metered white light source. The best source is - of course - sunlight, with all the wave lengths. You can achieve the same white level with LED where you won`t see difference with your eye, but the light will not have all the wavelengths, therefore the objects you are filming cannot reflect the wavelengths that are just not there. You will see the color shifts in these objects with digital cameras, because the image is already reproduced, but you will not see it through the film camera viewfinder, because your eye is easily tricked. LEDs will have troubles showing violet and cyan, but also some of the warmer wavelengths that are in skin tones - this is caused by the mechanism of LED light. The diode by itself is blue color, because that gives the highest output. The blue light is then filtered by yellow-orange luminophosphor changing some of the wavelengths to warmer. By this you get two quite steep hills of rich wavelengths in spectral power distribution while some will not be as rich.

You also cannot effectively fix it with 1/8 gels

Thanks so much for the help bud. I do really appreciate it!
