Autoexposure control - More prescan functions

Autoexposure adjusts the scanner exposure to compensate for the density of the
film. To use the autoexposure function with color slides, the auto-expose-for-slides
option must be checked in the preferences box. To use it with color negatives, the
exposure control for negatives must be set to auto in the preferences box (p. 44).
AE area selection allows the use of a small area within the image to determine the
scan exposure. Use AE area selection with high or low key images, or when the film
has been badly exposed.
The AE lock function sets the scanner exposure based on the exposure determined
for a specific prescan with or without the use of AE area selection. This exposure
can be applied to scans of different images. This function is useful when scanning a
series of high and low-key images that have consistent exposures. By locking the
exposure on one frame when scanning a bracket series, the scans of the other
frames will show the exposure difference in the each frame of the series.

AE area selection

Click the AE-area-selection button
after prescanning the image.
Pressing the shift key changes the
dotted cropping frame to the solid
AE area frame. While pressing the
shift key, use the mouse to adjust
and move the AE area. The meth-
ods 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 represent
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.

AE lock

After making a prescan or setting the exposure of the ref-
erence image with the AE-area-selection function, click the
AE lock button to fix the scanner's exposure.
Select another image and click the prescan button to view the result with the set
exposure. To cancel the AE lock, click the AE lock button again. The prescan and
final scan will be made with the locked exposure setting until the AE lock is can-
celed.
