ISO Camera setting carried over from film cameras. Film would be rated by sensitivity to light. 10 0ISO is for taking images with lots of light like a sunny day. 400 ISO would be used in lower light such as inside a room. Aperture Priority camera mode On digital cameras usually symbolized as A or AV. Allows you to control the camera by aperture setting manually and the shutter speed compensates. Shutter Speed camera mode On digital cameras symbolized by S or TV. Allows for photographer to control the shutter speed manually and the aperture compensates. Manual camera mode Allows the photographer to control both the aperture and Shutter speed manually. Symbolized with M on digital cameras. Aperture the size of the lens opening that lets in light to the digital camera sensor. The opening can vary in size depending on the lens used. Used with shutter speed to control the amount of light reaching a digital cameras sensor. Fstop The size of the lens aperture in number form. The smalller the number - the larger the hole opening - ex. F2.8. The larger the number the smaller the hole opening - ie. F22 Shutter Speed Digital camera setting that controls the length of time the shutter is open to allow light through the lens to the sensor. Varies from very small fractions of a second to several seconds long. Over Exposure Pictures are very pale and almost white. A result from too much light entering through the lens to the sensor. Under Exposure Pictures are very dark. Result of not enough light getting through the lens to the sensor. DSLR or Digital Single Lens Reflex A digital camera with a single lens that is detachable. Typically there are a range of lens to use in various types of photographic situations. Sunny f16 rule A rule to use as a basic metering point for digital cameras. By setting the lens aperture to an f-stop of 16 and the shutter speed to the ISO setting, a correctly exposed image can be taken on a bright sunny day. Aperture full stop Controlling the exposure by either increasing or decreasing the light hitting the sensor. Example: going from f5.6 to f8 decreases the light a full stop - going from f11 to f8 increases the light a full stop Shutter speed full stop Controlling the exposure by either increasing or decreasing the light hitting the sensor. Example: going from 1/60 to 1/125 decreases the light a full stop - going from 1/60 to 1/30 increases the light a full stop ISO full stop Controlling the exposure by either increasing or decreasing the sensitivity of the sensor to light. Example: going from 200 ISO to 400 ISO increases the sensor sensitivity - going from 200 ISO to 100 ISO decreases the sensor sensitivity. Basics for operating digital camera
