Just saw on Mastodon that the Resynthesizer plugin will be ready to use with GIMP 3.0
Along with other third-party plugins developed for GIMP, like G'MIC and BIMP, Resynthesizer is so integral to our workflows that it's easy to forget that it's not part of the core project.
Very cool.
I have been playing with Omnigen (a new open source image-based AI) for unblur and exposure adjustment. Works pretty darn well, and have considered creating a plugin for it for GIMP if no one else does.
