After getting my Scheme plugin to work (add overexposed and underexposed versions of a raw image, to recover some shadow and highlight detail) and working out the detail of how I then recover from the reduced-contrast result (well duh!, G'MIC for Local contrast enhancement), and then fine-tuning my own process, I've concluded that it is "good enough".
It is called "Three Exposures" and sits in Filters -> Enhance. Since the official plugin registry is no longer operational, I've put a page at http://www.zarniwhoop.uk/three-exposures.html with small examples of the result - each links to a series of less-small examples to show what I did (if only as a "don't do that, then" example for the good photographers out there). The download link is at hte bottom of hte page. It works with ufraw and gimp-2.8: if people on windows or mac can convert their raw images to xcf (or uncompressed png) files then it should work for them too - but it's only tested on linux. And as I note on the page, it does not work with 2.9. ĸen -- I live in a city. I know sparrows from starlings. After that everything is a duck as far as I'm concerned. -- Monstrous Regiment _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
