TRANSCRIPT
Iris
• Controls the amount of light entering
the camera
• Does not affect the image
• Opening size is measured in f stops
f1.6 f2 f2.4 f2.8 f3.4 f4 f4.8 f5.6 f8 f9.6
f11
1 f stop doubles (or halves) the light
entering the camera
Zebra
• Three positions - off, 70%, 100%
• Pattern only appears in viewfinder
• Use 70% for (white) faces
• Use 100% for general scenes
Shutter Speed
• The faster the shutter speed the less
light entering the camera
• Standard shutter speed for PAL is 50
• Slower will cause ghosting
• Faster will cause strobing
Gain
• Increases the electronic sensitivity of
the camera sensors
• Increases noise or grain of picture
ND Filters
• ‘Neutral Density’
• Generally used in bright sunshine
• Can be used to reduce depth of field
Lighting -
Shot or scene?
• Think about continuity
• Think about space
• Think about style
• Think about equipment and crew
Lighting
• Takes time and effort
• Experiment
• Check using the viewfinder
• White balance every setup
• Use manual iris
Three Point Lighting
• Use as a general principle
• Think about the three components
• There is no ‘right’ way
Key light
• Think about direction of actual light
• Be careful not to make it too bright
• Think of natural (sun) light as the key
Back light
• Use to separate subject from
background
• Or for effect
• Unlikely to be possible in sun - so think
backgrounds
Mixed light
• Use blues on tungsten lights
• Or use for effect - warm interiors
• Think about white balance
