Figure 1: Camera structure (Lecture notes)

Iris: control the flow of light entering the lens. Iris is measured by f-stop, indicated by sequence of f-number f/1,  f/1.4 , f/2.... (The lower the f-number, the larger the lens opening)

Figure 1.1: F-number(Lecture notes)

Shutter: small plastic sheet that opens and closes to allow light onto the film or prevent light from reaching the film.

ISO :the sensitivity/the signal gain of the camera's sensor. The common ISO camera settings are: 100, 200, 400....

**The lower the number of ISO the less sensitive your camera is to light and the finer the grain**
