I try to visualize regardless of format. Sometimes the negative surprises me while printing.

I never have done much street photography, but I did shoot a lot of sports for a newspaper. I would try to visualize my shots then, too, as I had only a 35mm camera and no motor drive. I would be sure I knew the sport and the teams well enough to anticipate where action would take place, then check the light and focus for that place. I got the shot most of the time, and every one of those shots was framed well enough, in focus and exposed properly. In reading about W. Eugene Smith, I think he used a similar technique for many of his photographs.

I think that, regardless of format and subject matter, you simply must have a lot of experience with your materials so that you can anticipate what's needed to get a printable negative.
