Thanx for the suggestion!.. i didn't think of coloured gels..
but i tried with cheapo cellophane paper over my flash and shone it on white mahjong paper yesterday... Its very hard to get a even light even on a small piece of mahjong paper.. and furthermore the blue color i get looks "neon-ish"... Is there a correct way of doing it so that the background colour appears more "natural" ?
alternatively..I was thinking.. Can a dark backdrop, eg. a navy blue backdrop, double-up as a black one? By limiting the light reaching the backdrop and thus underexposing the backdrop, will a blue backdrop turn black in practice? If possible, maybe I will get a white and a dark-blue since I cant afford too many.. haha
Appreciate any replies, or any referrals to online sites I can read up on lighting backdrop paper .... can't seem to find anything on this topic.. Thanx!
