Aperture, Shutter Speed, ISO, DOF, & Dynamic Range.
Aperture- the opening of the lens diaphragm through which light passes. It is measured in f/stops, the lower the f/stop the more exposure to the sensor because the aperture is larger. Higher f/stops means the aperture is smaller and there is less exposure.
Shutter Speed- the amount of time that the shutter is open exposing light to the camera sensor. It is measured in fractions of a second, and the quicker the shutter speed the better you can capture quick moving objects. When the shutter is slow moving motions will be more blurred.
IOS- measures how sensitive your sensor is to light. A higher number means more sensitive to light and can take photos in darker situations.
4. Depth of Field- is controlled by the aperture the distance from the subject and the focal length, its the zone of sharpness that will appear in focus. Small zones of focus are shallow DOF and large are deep DOF.
Dynamic Range- is the difference from the lightest to the darkest parts of the photo, from pure white to pure black.
