Another beautiful image, Ron.
Myself, I've never used filters until recently. I've begun to use a yellow for my outdoor shooting, and will soon add an ND8 to liberate the wider apertures for daytime duty.
An orange for portraiture may be on the cards, and probably a red for a bit of outdoor drama too.
Does anyone use blue or green, or is it worth giving these a miss ? I shoot a little scenic imagery, and also soon enough a bit of urban nighttime again too.
I anticipate carrying around the above with me when shooting for when they're needed, and wonder what people use to carry their filters around in. The above are mainly for use with my M3, and would like to keep them accessible, but also in some sort of compact manner.
