And everything that is required is written in the EXIF data (that it was DR auto, that 200% was chosen, and the provided ISO is the same as if DR was chosen manually).
I was asking about this a few days ago, and wrote a LUA script to manage this automatically (to at least have a style correct the underexposure and the basecurve). It works, suprisingly, quite well. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
