er, from what i know of physics, won't work
it's like if u shine a red light onto a blue ball, the ball will appear black

this is how it works
when a blue ball is placed under white light, the ball reflects blue light and absorbs the rest. thus, the ball appears blue to u
but when u shine red light onto it, it absorbs all the red light. no light is reflected and hence, u see it as black

so if u use a colour filter for ur flash, the photos u take might appear darker overall. this point cannot confirm cos i never try b4 :p

Make sure to leave some gap between the front surface of the flash and the plastic sheet or else the heat generated might burn the pastic or worse still burn the front surface of the flash.

In the early days, fashion photographers use exposed film to cover the flash. This provided a kick of "sunset" color in the photos. Furthermore, they are usually more rugged and plentiful!!

yes, make sure you dun melt the p[lastic over your flash, the power output of a flash is very high. and dun do repeat firing, cause a material over the flash m,ight prevent heat from diserping and hence overheat the flash.
I do know tat some put a layer of colour tint over thier flash to 'warm' upz the colours, sort of like a 81b filter over the flash.

cheers =p
