Acquire dust off reference data.
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.
Image Dust Off Reference Data
The same reference data can be used for photographs
taken with different lenses or at different apertures.
Reference images can not be viewed using computer
imaging software. A grid pattern is displayed when
reference images are viewed on the camera.
This option determines how long the monitor remains on if no operations are
performed during menu display and playback (Playback/menus), while
photographs are displayed in the monitor after shooting (Image review), and how
long the exposure meters, viewfinder, and information display remain on when no
operations are performed (Auto meter-off). Choose shorter auto-off delays to
reduce the drain on the battery.
