Living near the beach and with a trip to Jackson Hole coming up, I'm trying to get my filters together to make sure I have all my bases covered. Currently I have:
.9 GND SE
.6 GND SE
All Lee's and their filter holder. I'm thinking I may need a reverse GND. Should I go .6 or .9 and by who, other than Singh Ray, makes them in good quality? 4x6 size.
