Been searching around to see what this actually does, but I can't find it's function or how to change it. If possible, I'd love to remove the grain (or at least tone it down) on the Grainy Film art filter. I love the contrasty black and white, but the grain is just too much for me. I already recreated the filter pretty closely in Aperture, but it would be nice to have it all done in the camera. (If anyone wants the preset, just let me know) Sorry if this question is an easy one. I just made the switch from a Nikon DSLR setup I seldom took out except to do portraits, to the Oly. Still getting used to it, and I find the menus pretty cumbersome and confusing.
