- 2x screen mode : used 2 layers with screen mode on the original
- gimp shadows and highlights is the gimp filter under 'Colours'
- divide layer is the workflow from trierwick
- luminosity masks is a plugin from ofnuts (I think), I used the 'M', 'MM' and 'MMM' mask
- the shadow recovery script can be found here: https://www.gimphelp.org/contrast_shadow_recovery.html
If you want to use Luminosity masks to boost shadows you have to use one of the dark masks (DD, likeky). Otherwise the boost occurs on midtones that don't need it.
