Konica Minolta DiMAGE Scan Dual III AF-2840 - Manual (Page 51)

Click the AE-area-selection button after
prescanning the image.
Pressing the shift key changes the dot-
ted cropping frame to the solid AE area
frame. While pressing the shift key, use
the mouse to adjust and move the AE
area. The methods used to manipulate
the frame are the same as the cropping
frame except that the shift key must be
held, see manual cropping section on
page 38.
Place the AE area over the section of
the image to be used to determine the
exposure. Usually placing the area over
the subject of the picture will produce
excellent results. The area should repre-
sent on average the mid-tone of the image.
Click the prescan button to view the effect on the exposure. AE area selection can be canceled by
pressing the AE-area-selection button again.
