If you have a basic point and shoot digital camera, your shots will be limited but they are possible. If the graduation is indoors, lighting will pose problems, so set your ISO to a high setting (like 800 or greater) so that you can be able to freeze the motion and prevent blurry images. If it is outdoors, you should be able to just point and shoot away as normal. Remember, it’s not the camera, but the photos that makes the photographer!

If you have a digital SLR, you will want to have a few different lenses on you. At the ceremony and depending on the types of shots you want to get (wide, medium, or close-up), you will need a wide angle lens (35mm equivalent of 16-35mm), a standard zoom lens (24-105mm equivalent), and a fast zoom lens (70-200mm F/2.8). Ideally, you should have F/2.8 zoom lenses for maximum versatility and to blur the background behind your subject(s) for very pleasing portraits. If the graduation is at night or outside in bright sunlight, it will also be a good idea to bring a flash and a diffuser for those outdoor portraits to give some much-needed sot fill light.

You should try to sit as close to the stage as possible for obvious reasons. Be sure you have a clear line of sight and that there are no obstructions in the way between you and the stage to block your shot. If you will be using a tripod, get there earlier to setup and “stake your ground.”
