One of the most helpful things for this sort of question is to take a sample strip of negs in your left hand, a digisnaps camera in your right hand, hold the negs so they are lit from behind (by a window + sky for example) and make a focussed picture. Then people can comment on what your negs look like in comparison to theirs, and discuss actions to change the results. Secondly, make sure your paper isn't ancient and/or cooked, as that can have unfortunate results on what can be printed successfully!
