Single Lens Reflex Camera
If you have a knack for photography, friends or family members may ask you to photograph their wedding. For this task, a digital single lens reflex camera is imperative. These cameras are the choice of professional photographers all over the world for the ease of use, quality of shots and versatility. The key function to a single lens reflex camera is the ability to change lenses. If you're shooting the wedding officially, take wide-angle and zoom lenses for the job. Keep your camera bag handy so that you can switch lenses when necessary.
Advanced Digital Camera
An advanced digital camera will give you a variety of user-friendly options, yet isn't as bulky as a single lens reflex model. This style of camera typically has a quality zoom, a number of shooting functions, including the ability to shoot with and without flash and in low light, video mode and panorama settings. You wouldn't want to rely on an advanced digital camera if you're asked to be the wedding photographer, but this style of camera is suitable if you're a guest.
Point And Shoot Camera
What a point and shoot camera lacks in functions, it makes up for in its compactness. Point and shoot digital cameras have moderate zoom functions, a flash and typically a few other settings, including a video mode. They're lightweight and portable, and will fit easily it the pocket of your pants or suit jacket or purse. These cameras won't provide professional-quality shots, but they're more than adequate for capturing the moment.
Cellphone Camera
Average guests may wish to snap some candid shots at the wedding, but may not relish the thought of lugging around a heavy camera and camera bag throughout the day. If this is the case for you, your cellphone camera will do the trick. It's light, portable and you're likely already carrying it. Many cellphone cameras will also shoot video, which is ideal if you wish to take short clips of the day's events.
