Frame Rates
(frames per second)
Shutter Speed
(fraction of a second)

4. Part 2: The Body
The camera body contains the shutter, image
sensor, the capture medium, support electronics,
and control interfaces.
Frame Rates
The number of frames captured in a second
(frames per second)
Shutter Speed -
The time light is allowed to strike the image
sensor to create a single image.
(fraction of a second)

5. Part 2: The Body
The camera body contains the shutter, image
sensor, the capture medium, support electronics,
and control interfaces.
Shutter Speed
(fraction of a second)
Generally, shutter speed must be at least half of the frame rate. At
30 frames per second, the shutter speed will be approximately
1/60th of a second.
It can be faster if the camera allows.
A higher frame rate requires a faster shutter speed.
Shutter speed can be increased independent of the frame rate.
A faster the shutter speed results in diminished blur
A slower shutter speed results in added blur.

Psychologically, we perceive
bluish images as cool
And more orange images
as warm

58. Part 2: The Body
Color Temperature and White Balance
Light exhibits different colors based on its temperature.
The higher the temperature, the bluer the light
The lower the temperature, the redder or more orange the light

59. Part 2: The Body
Color Temperature and White Balance
Sunlight, at around 5000 – 6000 degrees kelvin, is bluish, as is
fluorescent light, at around 5000 degrees kelvin

60. Part 2: The Body
Color Temperature and White Balance
Tungsten incandescent light, at around 3200 degrees kelvin, is
reddish or orange

61. Part 2: The Body
Color Temperature and White Balance
White balance is setting the camera sensor to a color
temperature that assures that white appears white.
