Hi,
For the record: I am quite happy with darktable as it is, I am grateful for all
the work that has been put into it, and I do understand that people work on
this in their spare time.
On this background, I don’t think it is improper to have some wild ideas J
For me personally, the planned printing module would really be a big step
ahead. The support for 30bit display modes would be next on my wishlist, but I
realize that the devs don’t have 30bit hardware so this is not going to happen
too soon – which is fine. Gift horse etc (OTOH, I would support an initiative
to buy a 30bit monitor for some devs).
Raster masks would come somewhere after this, on my wishlist, but I think they
can be useful on a more general level. Imagine loading any grayscale image as a
mask: That would offer a lot of artistic possibilities. Definitely a nice
feature for darktable 3.0…
Cheers
Michael

Betreff: RE: [Darktable-users] Luminosity Masks in Darktable?
I’m really regretting I suggested this now. Clearly it can’t be done without a
pretty major rework in dt adding a whole different type of masks for I wonder
what purpose? Being able to have a static mask generated from parametric would
be nice and occasionally useful but overall, given the choice, I’d rather have
the dynamic parametric masks dt has and adding a new one tuned to the
individual iop use needed really isn’t that hard.
So if the devs want raster masks, and have other grand plans for using them
then great. But I’d hate to see that much extra bloat added to dt just for
saving the odd parametric mask creation. If it was just for that I’d
personally rather do without.
So in the spirit of the earlier +1 comment to my earlier post, can I add a -1
to my own now J

Hi,
I had a look at the XMP specs – e.g. JPEG thumbnails are stored as a base64
text string inside the XMP. darktable could do the same for a grayscale mask
PNG or something like that. You might define a “darktable” namespace and e.g.
an array to hold masks and their locations.
I don’t know if this is practical though, it might bloat the XMP file.
Alternatively, you may store an URI referencing the masks via a relative path,
but that makes moving the images slightly more cumbersome – one would need to
move not only DSC_101.nef and DSC_101.nef.xmp, but also DSC_101.nef.masks
IMHO both is acceptable to get nice raster masks – but of course, I’m not a
developer, that’s not for me to say, darktable is great as it is.
Cheers
Michael

Hi,
This as already been discussed may times.
The (main) problem with the idea above is that it would require to create a
raster mask from the parametric one (parametric -> vector drawn mask is
impossible in most cases). And this is not an option as we have to store it in
xmp.

Something like that, though I don't see an easy way to do that that
would still be compatible with embedding the history stack in the
xmp/jpg. Though I'm not a developer, so what would I know? ;)
