So yes I am somewhat of a newb but if I may I have a question that I didn't really find an answer to searching the forums. I have been given an assignment through school to shoot B/W architectural exterior night shots with a 4x5. My instructor suggested that I use "Kodalk" to aid in development of my negs. He also used the term balanced alkali interchangeably but I haven't been able to find out much about it other than how to produce some. The questions that I have are: Does it do what I think it does as far as producing a larger tonal range therefore working better for night? How would I use it inline with Sprint systems developer, stop, and fix which is what we use at school? In place of the developer or in conjunction with? And what kind of times would I be looking at for something like Kodak T-Max 400? Thanks for any direction.
