Autoexposure

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

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.

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 lock

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.
