I have a question. I shot the first part of a night exterior scene yesterday with a dedollght LED kit to light the actors (the street is illuminated by the street lamps). I dimmed the dedolights to 2800k to match as close as I could with the street lamps. Next week we're shooting the rest of the scene but I won't be able to take the same kit. The only light available are two Rotolights LED bicolor. But these lights will only go to 3150k.
I wanted to match both lightings. Even if I WB the camera to 3150, the street illumination will change. So my best option will be to try to transform the 3150k to 2800k, using CTOs. Any idea on the measure I need? Maybe 1/4 is enough?
