Is any filter of these brands, other than cokin, made of glass, or are they all plastic?
Just curious... I am new to photography but I take very good care of everything I own, and that includes my photo gear. However, I have scratched both of the Cokin GND filters I own, even though I've been careful when using them. Fist one got scratched while installing it in the holder, the second while replacing it in case it came in. How? Please don't ask, I don't know, but it must have been in the stupidest of ways.
Also, are these other brands real GND filters? I feel my Coking GND filters (120 & 122) give a color cast to my pictures, so they aren't actually ND.
