I shoot mainly 35mm, most often with the Nikon that my Dad bought in Japan in 1969. I love the decisive clunk of that heavy shutter and the excitement of winding up a roll of film I've just finished.
My go-to color films are Kodak Elite Chrome 100 and Fuji drugstore color negative film. In black & white I prefer Plus-X. I get my E6 and C41 developed at Vista in NYC, but I develop my b&w at home, these days mainly in Diafine. I love the look of film, and don't do much digital post-processing. Often I'm just trying to get my scanned images to look like the slides.
