B+W 8x10 Sheet film suggestions

[bulrich]

Been away from the forums for a bit and busy photographing. For the past 8 yrs I've been working exclusively in color and have a few ideas recently that I'd like to try out in B+W. Since I've only worked with B+W roll films in the past I'd like some suggestions for a good sheet film.
Generally I am photographing exteriors or interiors in mixed lighting. Or portraits. Currently use Fuji 160 when I can and the Portra 400 for either portraits or very long exposures (some up to half an hour).
Thanks in advance.

You cannot go wrong with Tmx/Tmy. Ilford is good, but not quite the same quality control. Freestyle sells a lot of new eastern european emulsions. If you can stand an occasional bad sheet or two, EFKE is very interesting film.

My favorite was simple Tri X but did notice the Ilford and Efke. Never liked Ilford roll films much but things change ;)
What do you mean by interesting regarding the Efke?

Efke 25 is very fine grained and somewhat orthochromatic. Unlike any other 4x5 film that I have used. They also have full ortho film and IR film. Adox also has interesting products, including the revived Agfa 111 paper.

I'm many of you have seen this but nice mention and discussion of film and process.

I must admit that Efke 25 is my favorite b&w now. It looks wonderful when developed using pmyk.
