Shutter Speed - Canon EOS C70 Instruction Manual

Shutter Speed

You can set the shutter speed according to the shooting conditions. For example, you may want to set slower
shutter speeds in darker environments. The camera offers the following modes.
You can also perform this function remotely using Browser Remote on a connected network device (A 159).
[Speed]: Allows you to set the shutter speed (in fractions of a second). You can select the increment to use when
adjusting the shutter speed between 1/3-stop and 1/4-stop increments.
[Angle]: You can set the shutter angle to determine the shutter speed.
[Clear Scan]: Set the frequency in order to record CRT computer monitors without displaying black bands or
flicker on the screen.
[Slow]: You can set slower shutter speeds to obtain brighter recordings in places with insufficient lighting. This
mode is not available when slow & fast motion recording is activated.
[Off]: The camera uses a standard shutter speed based on the frame rate.
Available shutter speeds
The individual setting options that can be selected will change depending on the frame rate used.

• You can also use direct touch control (A 49).
Using slow shutter mode
When recording in dark surroundings, you can obtain a brighter picture by using slow shutter mode. You can
also use this mode when you wish to add certain effects to your recordings, such as blurring the background
during panning shots or recording a moving subject with an afterimage trail.
• Image quality may not be as good as when using faster shutter speeds in brighter surroundings.
NOTES NOTES
• When recording under artificial light sources such as fluorescent, mercury or halogen lamps, the screen may
flicker depending on the shutter speed. You may be able to avoid flicker by setting the shutter speed mode to
[Speed] and the shutter speed to a value matching the frequency of the local electrical system: 1/50* or 1/100
for 50 Hz systems, 1/60 or 1/120 for 60 Hz systems.
* May not be available depending on the frame rate.
