1. Unit 57 – Photography Controlling the camera

2. There are four main controls
Focus
Shutter speed
Aperture
Film speed

3. Focus helps direct the viewer’s gaze

4. Shutter speed controls movement
1/15th of a second /500th of a second

5. 1/10,000th
of a second

6. 4 to 8 hours

7. Aperture – controls depth of field
Small aperture (f:22) = large depth of field
Large aperture (f2.8) = small depth of field

8. Film speed is measured in ISO
50 ISO film is used in very bright conditions and produces very fine-grain images.
125 ISO film is used in normal conditions and produces fine grain images.
400 ISO film is used when the light levels are low and produces grainier images.
1600 ISO film is used when light levels are very low and produces very grainy images.

9. Film can also be push-processed to deliberately enhance grain for artistic effect.
The sensitivity of a digital camera can be changed in the menu at any time
