Processing an Image

Just for fun I thought I'd post a quick comment on how I processed an image I took at Rodin's Atelier in Meudon.

... and here's what I did to it: 

  • Let the in-camera meter do its best
  • Ricoh 55mm wide open at f/2.2  
  • *click* the shutter 
  • Opened RAW image in RawTherapee
  • Applied my 0EV Digital Zone System curve
  • Adjusted the ends of the curves for pure white and pure black
  • Opened the image in the Gimp
  • Back in RawTherapee, processed the sky for tonality and contrast
  • Opened the sky processed image in the Gimp as a layer over the first image
  • Gimp selected the sky of the first image
  • Added a black mask to the second layered image
  • Filled the selection area in the mask with pure white
  • Adjusted the mask "sharpness" to Gauss soften with a 10 pixel radius
  • Flattened the image and saved

Done.  That's it.  That's all it took to get these the way I wanted.

The trick, of course, was protecting the whites/highlights, then applying a correct Zone 3 thru 7 1EV step curve, and stripping in the sky.
