Quote:I may drag the Background layer of some photos on top of others while looking at all of them in tiles.
Then, I have a one-click batch process that duplicates the stamped-visible layer, adds High Pass Sharpen with Soft Light Mode and a layer mask, and then adds a Stamp-Visible layer on top of that. [/color]
In the spirit of Gimp and their users, while easy does not come into it, not imposible is there. Had a dabble last night.
In Gimp 2.10 making a simple plugin might look like the attached. It is very linear, the method much as described. It does use the Gimp g'mic plugin for high-pass. The gmic_gimp_qt plugin contains hundreds of filters and is a worthwhile addition. (I did try the Gimp GEGL high-pass but it defeated me, it has a mind-of-its own about layers).
Get gmic_gimp_qt from http://www.gmic.eu The Windows version has an installer.
unzip for_gmic.zip and put for_gmic.py in your plugins folder.
Not ideal for new users, a missing comma / bracket / wrong-or-missing parameter and a plugin does not work.
Edit: There is a Macro function in the timeline, but for Gimp 3.2 (or later) https://developer.gimp.org/core/roadmap/...-recording do not hold your breath.
Example as a quick animation: https://i.imgur.com/amVdHRx.mp4 Gives a small sharpening effect.
