DSLR stands for “digital single lens reflex
A DSLR is a digital camera that uses mirrors to direct light from the lens to the view find, which is a hole on the back of the camera that you look through to see what you are taking a picture of.
Exposure: is the amount of light collected by the sensor in your camera during a single picture.
If the shot is exposed too long the photograph will be washed out.
If the shot is exposed too short the photograph will appear too dark.
Almost all cameras today have light meters which measure the light in the given shot and set an ideal exposure.
The three primary controls your camera uses for exposure are aperture, shutter speed, and ISO.
Aperture in a camera: SImply put, aperture is a hole within a lens, through which light travels into the camera body.
Size of Aperture- Large versus small aperture: In photography, aperture is exposed in f-numbers[for example f/56]. These f-numbers that are known as f-stops are a way of describing the size of the aperture, or how open or closed the aperture is.
Aperture basics: Small apertures [high f/numbers ie f/22} increase the depth of field, bringing both the main subject and background into focus.
Shutter Speed, also known as “exposure time”, stands for the length of time a camera shutter is open to exposure light into the camera sensor.
If the shutter speed is fast, it can help to freeze action completly.
How shutter speeds are measured: Shutter speeds are typically measured in fractions of a second, when they are under a second.
Rule of theumb for shutter speed: The slowest shutter speed for handheld photography is 1/60. Anything lower then that should either be on a tripod or on a straight, solid surface.
ISO: ISO is the level of sensitivity of your camera to available light.
General rule of thumb: Bright and sunny, 100 iso
Cloudy, 250 iso
Indoors, 500 iso
Modes on the DSLR:
M-Manual control over aperture and shutter
A-Aperture priority
