I'd like to be able to give more contrast on the model's face and taking the pictures in infrared photography by applying light make ups. Can anyone give pointer where I should search for such cosmetics?
For UV I would assume applying light UV cream will work but I cannot find specific IR blocking creams.
What about facepaint? Maybe you can paint your face in vertical stripes of different colors and take an IR photo, see which color looks best. You probably want greens and blues. I'll have to ask my wife how hard these shades are to find in typical makeup kits. Sounds like you'll need something more artist-oriented.
