Exposure» Exposure is determined by intensity of
light that pass through the lens and the time each frame is exposed to the light.
» Exposure = Intensity X TimeIt is controlled by aperture(T-stop) and (camera speed)Frame-rate
» Other factures that play a role in determining exposure are:
Film speed, Lighting, Filter, Shutter Angle

Aperture
The intensity of the light is controlled by aperture. The aperture of the camera is like the iris of the eye.

Film Speed
» A fast stock or high film speed refers to a film’s sensitivity to light. The higher the film speed, the more sensitive it is to light. ASA number
» Typical film speed:50D -100T and below: Slow200T-320T: Medium500T-800T: Fast

Camera Speed of Film Rate
» Standard Speed: 24fps» Slow motion: speed faster than 24fps» Fast motion:
Undercranking: speed slower than 24fpsTime-lapse: With significantly slower speeds, time is proportionally sped up.Animation.

The Variable Shutter
» Narrowing the angle reduces the exposure time.» Exposure time (shutter speed):
1/50second in 180˚shutter angle.» For achieving the selected f-stops or depth of
field» In-camera fades and dissolves

Light Measurements
» Incident light meters measure the intensity of illumination coming from the lamp and express the reading in f-stops, based on the film speed and camera speed or shutter speed input.
» Reflected light meters measure the light reflected from the subject and yield a reading in lumens per square foot
