As usual I am tapping the best photo resource I know to answer a few questions I have about film and developer combinations. The reason for asking is that I am new to LF photography and will be developing my own film for the first time. First, a bit more background for you to digest. I currently shoot Tri-X (400) in 120 format which is then processed at the lab. I like the look and feel of the film and the way it prints on Ilford MGWT, but I also know the film is unavailable in 4X5. As a starting point I have ordered a box of 4X5 TXP (320), the professional grade Tri-X. I am also open to other people's experiences with film in this speed range (320-400) as I tend to photograph people and like having an extra stop or to in hand. I also don't consider a bit more grain to be a distraction. You should also know that I plan to buy BTZS tubes to use in the development process. For all of you out there using TXP, what developers do you use, in what dilutions, development times, and why? What is the "look" you get when you develop the negs (shadow detail, contrast, etc)? What other benefits do you realize? What are the disadvantages if any (price, toxicity, volume, mixing, etc)? For all of you who don't use TXP, which film do you use, developer, times, etc and why? Thanks in advance.
