how to get grainer pictures in B&W?
I am interested in capturing all the imperfections in my subjects faces. Is there a filter that might help me with that?

You want to capture it? Are you sure? OK, try using a blue or cyan filter (B+W 470). These will bring out the redish tints that tend to be associated with skin blemishes by making them darker. Use as sharp a lens as possible, and critically focus it on the face. For as much detail to create more contrast of blemishes with areas of skin, use as fine a grain film as possible. Lips will go very dark. Among these films are (in order of how I would try them):
Kodak Plus-X Pan
Ilford Pan F
Ilford Delta 100
Kodak TMax 100
Agfa Agfapan APX 100
Fuji Neopan Acros 100
One not mentioned above because of its sensitivity to how it's developed is Kodak's ISO 25 Technical Pan, but it must be developed by a lab that knows what it's doing to for super fine-grain continuous tone negatives. Properly done, it can produce ultra-fine grain with excellent tonal scale that isn't muddy in the mid-tones.
If you're looking to *diminish* skin blemishes, then try one of the traditional yellow, orange, green or light red filters. Be cautious about the red though. It will shift colors more than the others, particularly of lips (make them pale). The classic portrait film with some graininess is Kodak's ISO 400 Tri-X Pan. It "gracefully" degrades into the grain structure. Others you might try are Ilford Delta 400 and Ilford HP5.
