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 each frame of the series.
After making a prescan or setting the exposure of the
reference 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 canceled, the
scanner is initialized, or the film type is changed.
Autoexposure
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 methods used to manipulate the frame are
the same as the cropping frame except that the shift
key must be held, see facing page.
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 is
canceled by pressing the AE-area-selection button again, make a prescan to reset
changes to the image.
AE area selection
AE lock
When AE area selection or AE lock are used with slides, the auto-expose-for-slides
option must be checked in the preferences box. When used with 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.
