If you are going to work with black and white film and do your own printing your first step with your new negatives is to make a proper proof sheet.  When I was first learning photography this was emphasized but I didn't always follow through.  Now it is an important step not only to be able to see what you have but as a guide to printing your enlargements.  Once the negatives have dried I cut them in 6 image strips and make a proper proof which will be stored with the negatives in a folder.
