Truly the best way to see obvious differences is to look at other peoples photographs. Not only will you see the results of a certain combination of film and developer, but also see the context of why somebody with experience used that combination to fulfill a goal. Try Flickr or the other photo sharing sites, the images are often accompanied by notes.

Processing should be based on knowledge, with sound reasons to do something, and with a sound plan. The alternative of going on a wing and a prayer is that you will never know if you made a mistake, or if it could be better.
