Shots of the valley in cloud. It slowly creeped after us all day suffocating all further chances of good photos.

The mountains of St Anton, Austria. Not much light to work with and only a few minutes of clear view as the clouds chased us all day.

Examples of Alternative Colour-swapping

660nm examples of using Tonee Gee’s alternative to colour-swapping in Photoshop.

  1. White-balance image
  2. Create a level adjustment layer
  3. In the levels output box (below the histogram) replace 0 by 255 and 255 by 0
  4. Change the layer blend mode to HUE

The obvious difference is the foliage coming out pink, rather than the usual yellow for 660nm. Second is the sky being more green, than with the normal colour-swapped image. This is however easily hue-shifted into blue.
