You don't have to print when shooting chemical images either. Before people posted images on the web they looked at slides on a lightbox or using a projector. For those of us who do print, the cost of the film is a small percent of the whole process. I'm squirming at the cost of 8x10 color film, but I already have far more good shots than I'll ever be able to print. What spooks me right now is the hundreds of sheets of museum board I need.
