Hi All!
Here’s a tricky image (I think) for you all. A snowy waterfall in a gorge under the noon sun. I’m having a lot of difficulty bringing out the rock structure of the waterfall and not blowing out the sky and snow at the same time. Here’s my attempt in Darktable, it still seems a little dark to me:
Hi @drcosquared
this is my attempt I tried to bring out the rock structure with 2x local contrast modules. I pulled down the highlights with an exposure module with a gradient mask and a tone-equalizer. I hope this is helpful to you
I think it’s interesting that both @sls141 and @Thomas_Do posted B&W versions of the scene. I just so happened to also photograph this scene with B&W 35 mm film (Kodak Tri-X 400). Unfortunately I underexposed a little, as I never used film in snow before. However, I love the contrast between the rock and snow.
Here’s the digitized negative, processed with negadoctor. I could probably extract more from it, but I’ve been keeping the film digitization as simple as possible:
