Originally posted by NotMyFatDog I did not realize that you could raise the shadows so much. I thought once something was dark, that was it. Thank you for the guide and Darktable suggestion, I'll download that now!
The following pics are shot with a K-7 but I have a KP coming in the mail (YAY) and will be going back with some practice and wise advice under my belt...
From a couple years ago, 16mm Rokinon lens... definitely thought to increase the ISO so I will try lower ISO next.
If you are happy with say, iso 3200, which is 5 stops of in-camera gain then you will be happy with 5 stops of shadow recovery in post processing.
If you do that shadow recovery with the simple exposure value tool then it will be basically identical to the iso 3200 shot.
If instead you use the curves tool (or similar acting sliders) you can bring the shadows up without frying the highlights.
The caveats to that in darktable --
A) in dt there is only 3 stops of exposure value available - the rest has to be done on the curves.
B) It is tricky to get the curves to tune it exactly right - a slight movement will make a big difference.
Take a look at the great advice I got here on page 6 for this exact purpose.
