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 expo-
sure. 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.
