So you want to be a photographer, but you don't know how to use your nice new fancy DSLR. Well, not to worry. I will help guide you through a typical Photography 101 course. Let's get started! This week we will focus on the individual parts of your camera and what they do. Your camera is made up of many essential parts: The body: The body is the housing for your camera. All sorts of companies make all kinds of camera bodies. The body of the camera only really effects how your camera will function and sit in your hand. The Lens: The lens may be the single most important part of your camera. Lenses on DSLRs are attachable and removable to your camera body, however, they are NOT universial. Lenses fit to specific company specifications. So you can not use a Nikon lens on a Canon body. However, there are a few companies that make lenses for other camera body manufactures at cheaper costs, such as Sigma. Lenses typically come either as zoom lenses or fixed lenses. Fixed lenses only have one zoom setting, so you can not zoom in our out with these lenses. Zoom lenses have a range that they can zoom in and out. Fixed lenses are usually higher quality, however, zoom lenses are more flexible to the situations you might find yourself in. Sensors and CPUs: A sensor is the part of the camera that actually captures light filtered from the lens. Size of a sensor will effect picture quality and ultimately price of the camera. Point and shoot cameras typically have very small sensors. Large, expensive DSLRs have large sensors. Sensors are what ultimately determine megapixel count. Flash Card: The flash card is what saves and stores your images. The most common types of digital camera flash cards are SD and CompactFlash cards. The speed that your flash card is important, because it will determine how fast you can write and store image data. Be sure to choose a high class rating for your DSLR flash card. (Class 10 for SD; Class 6 for SD) Battery: Most DSLRs come with high quality batteries that will last you a full day of shooting or more. DSLRs don't require you to use the LCD screen to take a photograph, which cuts down on battery usage significantly. Be sure to carry an extra battery with you, you never know when you might need it!
