It's just that none of the devs think this is a feature worth the time and effort to write code for. So either someone who actually wants it steps up and provides the code, or it won't happen. > > PS: In case you wonder, the dirty way is to > > add a Lua guide to the cropping module and > > from there call to command line exiv2/exiftool > > to get the data and then draw it. > > I was thinking more of an analogy to the > indication of sharpness in lighttable (ctrl-z). > This would mean a similar drawing, but a way > simpler task of finding the spots, which must > be really hard when qualifying image detail. > > darktable user mailing list > to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org signature.asc Description: This is a digitally signed message part.

I don't use those, but you seem right again. But in my case, a side effect would be to detect back/front focus with some lenses more easily, because, at least in my case, there is so much time between taking the shot and seeing it in darktable, that I wouldn't always recall my settings. darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
Re: [darktable-user] Focuspoints
I think the focus points recorded in the image are often irrelevant, e.g. if you use focus-then-recompose. The focus data in the image would probably show the central focus point, which may easily point at the background by the time the picture is taken. (I realise this is less of an issue with touchscreen focus on MILC and images taken with a phone).

I was thinking more of an analogy to the indication of sharpness in lighttable (ctrl-z). This would mean a similar drawing, but a way simpler task of finding the spots, which must be really hard when qualifying image detail. darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

This is going to very very hard, because each manfacturer and family of camera has a different way of indicating the focus. * fuji uses the pixel that was focused on: Focus Pixel: 1028 306 * canon uses the focus array, which one were in focus: AF Points In Focus : 21,24,25,39 AF Points Selected : 0,1,2,3,15,18,19,20,21,22,24,25,37,38,39 -- sknahT vyS darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

No that is not possible in any clean way.
