[Darktable-users] Metadata management

Adding stuff to the lua API is a bit complicated but not undoable, however it's hard to explain in a simple mail... the best thing is to look at the lua specific parts in src/views/map.c as a starting point, look around at how similar things are done in other users of lua out of the lua/ subdirect

Nice idea :) Use pink highlights as an indicator of over-exposedness and fix the color later. Ulrich Am 22.02.2015 um 20:36 schrieb johannes hanika: > there's a stupid trick you could try (see attached xmp). i learned it > from this mailing list, i think from david vincent jones iirc.. > > -jo

Thanks all! Even with highlight recovery disabled, we lose much of the details. Perhaps a programmatic way of doing something similar to what I did (computing some kind of (weighted) average of the original R-G-B-R photosite values and applying that to add fake luminance on top of 'average colour'

Hi, yes, I also can confirm that RT really excels in highlight reconstruction and is ahead of darktable (*). IMHO this has two aspects: 1) RT controls all this from one single panel. So there are only few clicks needed to get to the desired result. 2) Color reconstruction of blown-out highligh
