Press the shutter-release button the rest of the way down to acquire Image Dust
Off reference data.
The monitor turns off when the shutter-release button is
pressed.
Note that noise reduction will be performed if the subject is poorly lit,
increasing recording times.
If the reference object is too bright or too dark,
the camera may be unable to acquire Image Dust
Off reference data and the message shown at
right will be displayed.
Choose another reference
object and repeat the process from step 1.
When connecting the camera to a television or VCR, be sure the camera video mode
matches the device video standard (NTSC or PAL).
Reduce flicker and banding when shooting under fluorescent or mercury-vapor
lighting during live view (0 93) or movie recording (0 101).
Choose Auto to allow
the camera to automatically choose the correct frequency, or manually match the
frequency to that of the local AC power supply.

A Flicker Reduction
If Auto fails to produce the desired results and If you are unsure as to the frequency of the
local power supply, test both options and choose the one that produces the best results.
Flicker reduction may not produce the desired results if the subject is very bright, in which
case you should select mode A or M and choose a smaller aperture (higher f-number) before
starting live view.
Note that flicker reduction is not available when On is selected for Movie
settings > Manual movie settings (0 104) in mode M.
