The following settings for the automatic exposure correction are user-adjustable:



Mode:

Fixed shift by the given amount of stops (EV), the value is controlled through Preferences
– Exposure – Auto Exposure – Fixed Exposure shift.

Automatic calculation of the exposure compensation to shift the histogram ‘to the right’,
controlled through Preferences – Exposure – Auto Exposure – ETTR-style autoexposure
(shift histogram to the right).



Fine-tuning of the automatic exposure compensation:

Saturate up to NN% pixels – controls the per cent of the pixels that will reach the
saturation as the result of the automatic exposure correction.

Exposure shift limits:

Unlimited – no limit, goes all the way to the setting for Saturate up to NN% pixels

ii.

Hard limit – no more than the number of stops set in this field.

iii.

Virtual ISO – the limit depends on the ISO setting that was used to take the shot:



If the shot was taken at ISO in-camera setting higher that this limit, the
maximum exposure correction is 0.



For the shots taken at lower than this limit ISO setting in camera, the
maximum value for the exposure correction is equal to the difference
(in stops, EV) between the ISO setting in the camera and the limit set (for
example, if the limit is set to ISO 6400, and the shot was taken at ISO 1600,
the maximum amount of exposure correction is 2EV).

To switch off the exposure correction, making it 0 (or, if Apply Adobe hidden exposure correction is
ON, making it equal to that value of hidden correction), press the ‘A’ key on the keyboard. Second
press of ‘A’ will restore the previous correction.
