First of all, congratulations. Graduation is a true milestone and you should be very proud of your accomplishment. Senior portrait sessions can be done in studio, on location, or both. You will probably want some traditional photos including some with your cap and gown. And if ever there is a time to be creative, it is for a senior portrait. So along with a some traditional photos consider taking the oppurtunity to show a little bit of your personality. Why not get some shots of you at your favorite hangout, or with that car you have been fixing up a little bit at time.
