1. A computer-implemented method, comprising:
encoding an input image into a latent representation for the input image and, for each of two or more regions of the input image, a respective local exposure estimate;
computing synthesized transformations using the local exposure estimates, latent representation, and target enhancement levels; and
applying the synthesized transformations to the input image to produce a set of exposure transformed images, wherein each exposure transformed image in the set is associated with a different one of the target enhancement levels.
