I try to control the contrast such that I can print with a #2 filter. But let's think about the question a little more.

Contrast can be controlled via exposure, filters, and film choices on the camera side. In development we can exert contrast control through our developer times. On the printing side we have variables of exposure, filtration and development.

Since I try to print at a #2 and don't generally use filters, I use exposure and development to maximize the ability of my film to be printed at a #2. But all that does is get me in the correct range. I still need to fine tune the ultimate product (the Print) to make it the best that I can.

So, I think that we can use all of the variables to one extent or another to create the "fine print" that is the ultimate goal.
