Well, processing photos is quite new to me, so I'll record some of my experiences as I go along here.


Idea was to expose for the highlights, then boost the shadows in another layer. The use a mask to show the appropriate bits where they are needed. Alas the camera ISO was accidentally set to 800. This resulted in the boosted shadow bit being very very noisy, with horrible splotches in the red channel.


Do two conversions, one for highlights, one for shadows.

Shadows, noise processing

This seems to be one way of getting rid of the big splotches
