Pushing your film is exactly what you said. You underexpose it in the
camera, then overdevelop it. My pic of the week (http://www.wrightfoto.com/)
was shot on ISO 400 film which I pushed to 1600. At 400 that brand of film
in my delevoper requires 6.5 minutes of developing (I think), at 1600 it
took 9.5 minutes. Any pro lab worth the money that you pay them will be able
to push film. The reason that I do this is simply to have more sensitive
film, when I need the extra speed but don't have access to normal high speed
film. Many ppl push film to get grainy artsy effects. Some films have really
bad grain when pushed. Speaking of which I should say that Ilford's HP5+ (my
most loved film) can be pushed to ISO 3200 with better results (to me) than
Ilford's 3200 Delta...
