I work mainly in black and white silver photography.  Digital imaging is fine but I much prefer the feel and the process of film and a traditional wet darkroom.  I shoot mainly with 35 mm equipment, most of it 30 - 50 years old.  I also use a diffraction (or pinhole) camera that takes 126 film.  I use Ilford FP-4+ film and Ilford papers.  The film I develop in Kodak XTOL and the paper in an Agfa developer which is being discontinued, as is nearly everything in non-digital photography. Although these images are "black and white" they  actually contain many hues.  Sometimes this is a difference in the paper (especially the tonality of the silver, which can range from a very "warm" brownish-black to a very "cold" blue-black.  More often, its a result of toning the silver image itself.  I often create a brown and black "split tone" by partially toning the intermediate greys with sepia toner while leaving the deepest blacks as black.
