I can process all the common film types, C-41, E-6 and all sorts of b/w. I PREFER b/w for much of my personal work because I like to visualize with light and composition. Texture and Shape.
When you shoot in colour, you shoot with color in mind.
Good b/w is a more difficult media to excel in. I relish the challenge.
I will sometimes go out with my Leica and b/w film and actually NOT shoot, because the light is not right, with Colour, I could have shot, because the separation between subject and background is treated differently, and the colors of the scene can make the photo.
I also like the archival nature of well processed b/w negatives.
