This actually brings to mind a question I've had for a while - is there a rosco/lee product similar to the material chimera uses on their LED boxes? I've side-by-sided against opal, 250, hampshire and it's no rough match to any of them. The chimera material looks like a prismatic to me (like the materials ETC sells for their led units), certainly more diffuse with less loss than any of the usual suspects so I'm interested if anyone knows a similar roll material?
Chimera,s also have different levels .. to me the nearest thing would be sail cloth (well all nylon today ).. I wonder if you can buy that somewhere before it gets made into sails.. or buy a couple of dinghy spinnakers..
