I am running Windows7, and am looking for a command line utility to
modify the DNG's exposure and save to a new DNG, with the intent of
prepping for HDR processing.
For example, to make -2 and +2 EV modifications, Id like to do something such as:
converterapp "base.dng" -modifyexposure -2 "base-2.dng"
converterapp "base.dng" -modifyexposure +2 "base+2.dng"
I am hoping that whoever is reading this understand that the above is simply for
the sake of explanation.
My google fu is weak, I have searched for 4 weeks and turned up nothing.
May you be of assistance?
I am only interested in solutions that are command line, I can easily do this
with PS but that is not part of this project.
