4 Which element you choose as a priority will be the most important decision you make before taking a photograph. next

5 Choice of film speed affects the ability to achieve creative effects with aperture and shutter speed Commonly measured using ISO number 25, 50, 64, 100, 200, 400, 800, 1600 each is twice as sensitive to light as the previous

6 Speed of film determines its sensitivity to light Slow speed (ISO 25, 50, 64) less sensitive to light good for daylight depending on the light, may require longer exposure times/larger apertures Fast speed (ISO 400+) more sensitive to light good for night, indoors/low light depending on the light, can use shorter exposure times/smaller apertures
