My favorite b/w films are Tri-x and Agfa 100 or Rollei 100, and the old Agfa 25; I am curious about the new Rollei 25.
In general my staple film is Tri-x because of its versatility. I can expose this film at 400 and process it in Rodinal, and still have a very refined grain structure, or expose it at 800 ASA and process it in Acufine and also have a really beautiful grain structure.
Agfa 100 and 25 is just amazing especially when you process it in Rodinal; especially the 25 ASA.
As far as color, I like the Kodak 100 NC Portra, and for slide I think it is called Fuji 100F. I have had excellent results with that film.
I hope that helps, I would just encourage you to experiment and find a film developer combination that you like.
I would maybe start with a couple rolls of Plus-X and Tri-X, take the same picture at around the same time, then process one or two rolls of film in D-76 and the other rolls in Rodinal, then print the images and see what appeals to you more. If you have time and interest then I would start experimenting with other types of films and developer combinations.
However, if you do not have time to do this, you cannot go wrong with Tri-X or the new Rollei films and processing it in Rodinal. There are so many choices and each film and developer combination yield different, yet beautiful renderings of what you photograph; it is so subjective and just depends on you aesthetic sensibilities and mood.
Let us know your results.
