Re: [darktable-user] Is it possible to configure "alias lenses"

[Hans Vanpee]

I think I can adapt the script to write to the sidecar file (I am using
exiftool or exiv2, don't remember right now).

[Hans Vanpee]

Exactly, but, as you can see not everybody likes to modify raw files. I see
it as a way to complete the EXIF info where my camera doesn't record the
details I want.

Re: [darktable-user] Is it possible to configure "alias lenses"

[Hans Vanpee]

I have a script that injects the lens make and model for my manual lenses
(for Nikon but can be adapted if needed) in the raw files on import. If
you're interested I can share it with you.

[darktable-user] Export image: "unsupported output profile"

[Hans Vanpee]

I am trying to prepare an image for an online print service and I want to
export it with the (downloaded) icc-profile for the type of print I'd like
to order. The profile is stored under ~/.config/darktable/color/out/
(Fedora 25). I can select it under "output" in the "Export selected" panel.
When I start the export I get a message saying "unsupported output profile
has been replaced by sRGB". I tried importing the profile in Gnome but it
still doesn't work. Is there anything else I need to do?
I am using darktable version 2.3.0+561~g8bb04fd.

Thanks in advance,

Hans

Re: [darktable-user] Basecurve question

Hi Terry,

I still see the basecurve module in the master branch (pulled and compiled
this morning). Are you sure you have it enabled under "more modules"?

Re: [darktable-user] Nikon D750 support?

[Hans Vanpee]

This is a high contrast picture. When you open the levels module in
darkroom view and move the middle slider to the left you will get a
brighter picture. I don't know if you have some auto-levels feature
activated in Lightroom but you can get +/- the same result in darktable.

Re: [darktable-user] Nikon D750 support?

[Hans Vanpee]

Hi Jani,

Darktable works perfectly fine with the D750 files. I usually change the
base curve to the "Nikon D750" preset to get some more pop. The default
"nikon like" is rather dark.
Not all lenses are available in the lensfun database but it is possible to
add them yourself if needed.

[darktable-user] Lighttable scrollbar width

[Hans Vanpee]

I have following problem with dt 2.1.0: the scrollbar in lighttable view is
so narrow that I can't even click on it. When trying to click on the
scrollbar dt just toggles the right pane on or off.

I tried altering the margin property in darktable.css but this only affects
the scrollbar in the right pane itself, not the one that allows scrolling
through the list of images (the comment "this makes scroll bars super wide"
gave me false hope).

I am using Fedora 24 with gnome shell 3.20.4. All other applications have
normal scrollbars. I tried different themes to no avail.

Is there a way to modify this scrollbar width?
