I was wondering the other day, why do we even need software like Lightroom, Adobe Camera Raw or Darktable?
Their purpose is solely to retouch image in a most general manner (major tint/temperature, exposure, detail corrention) and then continue and do more work in other graphic software.
Why couldn't we just export RAW to some format with 16 bits per channel (that is more than enough for any camera) and then edit this photo in some non-destructive editor, like Photoshop or Gimp (with GEGL).
I am aware Lightroom is doing some very smart calculations when you stack effects, but so does Photoshop and GEGL (Gimp's new, non-destructive engine). So, why?
