Batch Editing
Increase or decrease the overall brightness of an image.
This module has two modes of operation:
manual Set the exposure, black level and clipping threshold manually automatic (RAW images only) Use an analysis of the image’s histogram to automatically set the exposure. Ansel automatically selects the exposure compensation that is required to shift the selected percentile to the selected target level (see definitions below). This mode is particularly useful for automatically altering a large number of images to have the same exposure.
