Jason,(posted 9241 days ago)I use Iflord Delta 100 or Delta 400 for portrait work. I really like Delta 100 for this sort of shot. I develop the film in Ilfosol S and print on Agfa RC paper. Using the above I've had some great results.
In general keep the exposure as short as possible unless you want movement in the shot for creative reasons.
Watch your shadows particularly around the eyes and nose. B&W allows you to play with shadow and light easily but can catch you out if you're not careful.
Studio pros have all sorts of lights, reflectors, softboxes, flash meters and even assistants to help them out. But most of all they have years of experience and that's the key. You have to take lots of pictures and learn from your mistakes!
You don't need lots of lights and stuff. Natural light is great! Domestic tungsten based lights are ok but for artificial light, specially designed photographic lights are the ultimate. Of course, not everyone can afford them, me included!
THE key to a great portrait shot (IMHO) is the relationship you have with the model/client. It really helps if they are relaxed and feel comfortable with you. Great lenses, lights, film etc. mean nothing if your model is as stiff as a board and can't give you natural expressions.
Hope this helps.
