DSLR: digital single lens reflex
A dslr is a camera that uses mirrors to detect light from the lens to the viewfinder The viewfinder is a hole on the back of the camera that you look through to see what you’re taking a picture of. Exposure is the amount of light captured by the sensor in your camera during a single picture If the shot is exposed too long the photo will be washed out If the shot is exposed too short the photo will be too dark Almost all cameras today have light meters which measure the light in the given shot and set an ideal exposure 3 primary controls your camera uses for exposure: aperture shutter speed and ISO Aperture is a hole within a lens through which light travels into the camera body Every camera that we know of today is designed like human eyes In photography, aperture is exposed in f-numbers (f/5.6) AKA: f-stops They’re a way of describing the size of the aperture or how open or closed the aperture is Small apertures (high f-numbers ie f/22) increase the depth of feel, bringing everything into focus Large apertures (low f/numbers ie f/2.8) soften background details DOF: distance to which objects behind and in front of the focal point appear to be in focus Shutter speed aka exposure time it’s the length of time a camera shutter is open to expose light into the camera sensor. Shutter speeds are measured in fractions of a second when they’re under a second Rule of thumb: slowest speed for handheld photography is 1/60. Anything slower than that should be on a straight, solid surface or a tripod ISO: is the level of sensitivity of your camera to available light The lower the number the less sensitive it is to the light and a higher number increases the sensitivity on your camera The component within your camera that can change the sensitivity is called image sensor or sensor General rule of thumb: bright and sunny, 100 iso cloudy, 250 iso indoors, 500 iso nighttime without a flash, 1600 iso M- manual control over aperture and shutter A- aperture priority S- shutter priority P- camera sets shutter speed and aperture Have camera around your neck at all times and hold camera by lens and hand grip if possible.
