At its simplest, it calculates an aperture and shutter value that you set your camera to for a correct exposure of a given scene. If you're confused by all the explanation, the three images above tell you everything you need to know. Conversely, the less light you let in, the darker the picture. Shutter speed is exactly what it sounds like: the amount of time the shutter opens to let light in. There are also other light metering modes: Exclusive promos, answers to your questions and inspiration every day! As a beginner, this can be immensely frustrating. Whether you’re shooting in automatic mode, a semi-automatic mode, or full manual, your camera always calculates the “correct” exposure settings, either to use or merely display when it thinks you’re under- or overexposed.

Generally, use Shutter Speed Priority mode for moving or dimly lit subjects and Aperture Priority mode for portraits or for playing with field depth. A dark subject, center-weighted metering. We know this because the little light on the bottom is lit up to the left of center. As such, I'll keep everything really basic and as non-technical as possible. If you need your image to be brighter, decrease the denominator in both the aperture and shutter speed and increase the ISO. Finally, if you have trouble shooting in manual, start off in auto to get a feel for the proper settings or switch to AV so the camera will automatically control only your shutter speed while you take care of the rest. The more practice you get in on full manual, the more you'll become comfortable with every setting on your camera. In photography, exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a frame of photographic film or the surface of an electronic image sensor, as determined by shutter speed, lens aperture, and scene luminance.Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region.
