I have lots of good quality glass from a greenhouse (obviously not optical quality glass) which I intend to cut down to make focusing screens for 5x4 home made cameras, home made wet plates for the same cameras etc... and I came up with the idea earlier of using some of the glass to make some interesting filters to fit my Cokin/Kood A holder.
Has anybody had any experience with making their own filters from sheets of glass? Any tips or ideas to share?
p.s. if anybody is local to me and want's some glass I have far more than I will manage to use.
