For people who use raw images from cameras, I've updated my Three Exposures plugin ("process" the raw images to get three different exposures, i.e a central, nominally correct, exposure and equal amounts of over, and under, exposure (plus or minus 1EV through to plus or minus 3EV, depending on the camera and the image, but typically plus or minus 2EV.

Thanks to help first from Helmut Jarausch, and then from Ell on the -dev list, I've now got a working version for 2.9 as well as the original 2.8 version.

I was embarrassed to discover that my initial files of examples had a couple of fubars in what I'd done (copied ufraw between machines, but ended up with it using an old idiosyncratic base curve, instead of the default straight line, and then used the G'Mic Tone Mapping filter on the assumption it was like the Advanced Tone Mapping filter, but actually it's more of a sharpening filter. So, I've reworked them, and used recent versions of gimp-2.9 from git when doing that (and then tested 2.9.6 on another machine, just to be sure).

The reworked examples are now at http://zarniwhoop.uk/three-exposures.html with links to the 2.8 and 2.9 plugins at the bottom of that page.

Typo'd the subject (should have been 'Updated', not sounding like an instruction to any existing users) and the 2.8 version has not changed, only the examples and the 2.9 version are revised.
