You should have your camera set up to name files progressively, so that the same file name will not be used more than once. You should be able to do this within your camera's menu... look in your manual. DC_3800, DC_3801, etc...... when you put in a fresh flashcard in the next # should be DC_3802..... And then as Jeff suggests coincide the camera image files with the names of the clients as they were taken, along with all the other pertinent information you will need to make contact with them at a later date. You may want to enlist the help of an assistant to help with the paper process, while you concentrate on taking images. Having the client hold a piece of paper with their name on it is NOT GOOD... imo it's unprofessional looking....

I am, therefore I create.......
