Once you have selected your favorite work, it is important to present it well. For some pieces, displaying the final design as exported from your graphics software will do. For others, it may look best if you photograph it. Package design and book design are examples of work that will be more impressive if the user can see the actual finished product. Try shooting the products yourself, but consider hiring a professional photographer (or friend) if budget allows, as the quality of the pictures is as important as the work itself. If you know a photographer, consider exchanging some design help for photography.
