I've been having trouble with running tone-mapping on infrared images. It makes for really good colors, but I'm losing too much detail in the highlights.
Then it hit me: do a 40%(ish) tonal-range selection on the original image, feather it by a couple pixels, copy it, and overlay it on the tone-mapped image.
Badda bing badda boom ... details are back.
I should probably be using frequency separation to create a selection, but for the life of me I can't figure out how.
The internet is so bad here that I can't watch any tutorials and I'm forced to make up my own Photoshop techniques.
