White Nylon (I have pink too but I haven't trred it yet so I don't know if the colour matters) With Hole(s) (You cant see them through the lens just in he photo) Without holes Having holes is a lot better, or else everything will be fuzzy (you can really see it if there are words especially small ones in the image). It has more of a smokey effect than anything. I put mine on by screwing my UV filter over top. I think an eleastic band will help just as well. There is also using petrolium (sp?) jelly on a plastic that is put over the lens. I'd like to try that one day.
