Re: No 8 gel filter

Any filter should require some adjustment, but a number 8 is
not very dark. I usually take my reading through the filter,
but I can't remember the adjustment. Maybe 1/3 or 2/3 stop
additional?

On a related note, I just finished shooting about 20
pictures in a 4x5 pinhole with a gel filter behind the pinhole.
Some shots had alot of "clear" dots in the negative- I am assuming
that some micro dust particles on the filter were projected on
the negative. Anyone else battle this?
