A DSLR camera stands for: Digital Single Lens Reflex. This type of camera uses mirrors to direct light from the lens to the viewfinder. Every camera we know today is designed like the human eye. Exposure is the amount of light collected by the sensor in the camera a during the picture. Having the shot exposed too long will wash out the photo and underexposing the shot will make the photo too dark, but almost al camera today have light meters which measure the light in the given shot and set an ideal exposure. The 3 primary controls this camera uses for exposure are aperture, shutter speed, and ISO. Aperture is a hole within a lens through which light travels into the camera body. It is expressed in F-#, also known as F-Stops. F-Stops are a way of describing the size of the aperture, or how open or closed the aperture is. A smaller F-Stop means a larger aperture,while a larger F-Stop means a smaller aperture. Small apertures increase the depth of field by bringing both the main subjects and the background into focus, while large apertures soften background details. Depth of field(DOF) is the distance to which object behind and in front of the focal point appear to be in focus. Shutter speed(exposure time), stands for the length of time a camera shutter is open to expose light into the camera sensor. If the shutter speed is fast, it can help freeze action completely. If the shutter speed is slow, it can create an effect called "motion blur." Shutter speeds are typically measured in fractions of a second. The slowest shutter speed for hand held photography is 1/60, anything lower should be on a tripod. ISO is the level of sensitivity of your camera to available light. The lower the ISO, the less sensitive it is to the light, and a higher ISO increases the sensitivity of your camera. The component within your camera that can change sensitivity is called, "image sensor" or "sensor." While shooting photos when it's bright and sunny you use 100 ISO, while it's cloudy you use 250 ISO, when you're indoors you use 500 ISO, and at night without flash you use 1600 ISO. The settings M on your camera stands for manual control over aperture and shutter speed, A stands for aperture priority, S means shutter priority, and p stands for camera sets shutter speed and aperture.
