Before/after comparison: Clouds over the city

before after

Time for another before/after comparison + some post processing details. This time a sunset photographed in Warsaw. BTW I would be very interested if you prefer these workflow details in form of a video (like this one) or in a form of a short article like the one you're currently reading?

I took 7 exposures at 1 EV spacing, merged them to HDR and tone-mapped in Photomatix Pro (which is Before). Then I edited my image with luminosity masks technique in Photoshop CC (After). As you can see the difference between output from Photomatix Pro and final result isn't huge this time. I mainly increased contrast and slightly increased saturation.

In the image below you can see what layers I used to create final image. Starting from bottom they are:
  1. Background - image produced by Photomatix Pro.
  2. Midtones contrast - I increased midtones contrast using Curves adjustments layers.
  3. Highlights contrast - added contrast to highlights in sky and grass
  4. Shadows contrast - added some contrast to darkest parts of the image and slightly brightened them up (I used Screen blending mode to get brightening effect)
  5. Highlights saturation - added some extra saturation to sky and clouds, especially to the yellows just above the horizon.
  6. Shadows saturation - added a bit of saturation to darkest parts of the image, especially purples and pinks (eg. roof of the building in foreground).
  7. Sharpening - added some sharpening.
