Hello everyone, I shoot Contax 645, and I am looking for a high contrast black and white film for street photography and portraits. I will be using this film in Egypt, Ethiopia, Kenya and Tanzania on assignment. I am looking for 320-400 ASA film. I currently use Tri-X, but want to test a few film choices out before I leave. I'm looking at: Ilford Delta 400 Ilford HP5+ TXP 320 Any suggestions? I will be sending the film to my professional lab and discuss with them the best way to develop the film.
