Re: NEF to JPG conversion yielding dark output

The image I shared with you was taken from twitter but what i have are very similar to that one. The images are not mine and unfortunately can not share them here for copyright reasons. I think you want to identify features on one image that will have moved (and possibly changed in other ways) betwe...

Re: NEF to JPG conversion yielding dark output
