[darktable-user] Re: [darktable-dev] ATTENTION: darktable master may have some GUI glitches

[Matej Martinovic]

Ok, I'm hoping for a compact version as the font is a bit to big for
my taste. Overall the GUI looks a bit "flatter" which is a modern
design approach, I suppose. It will need some getting used to, but
it's a step in the right direction.

BUT: somehow the buttons in the attached image got even smaller :D

Hello,

I'm not sure whether this is intended behaviour or a bug, please see the
linked image. The font is a lot bigger, and overall the GUI doesn't look as
"refined" as before.
I'm on darix's master screenhot on fedora with kde.

Re: [darktable-user] IIQ (P65+) help

[Matej Martinovic]

Hey Paul,

I now see the 4 different areas within your image CF003196.IIQ, as you
described in your original post. I think this is worth a bug report on
https://redmine.darktable.org/projects/darktable so the devs can see
what is going on.
You can create a new bug report after you've logged in to
https://redmine.darktable.org/projects/darktable.

Re: [darktable-user] Mark folder as 'done'

[Matej Martinovic]

I'm using color labels and or tags to organize specific collections.
Also collection presets are really helpful.
An example: I have about 150 images from my last trekking trip that
should be stitched into a panoramic image. I have tagged those with
something like "panoramic_singles". I can then filter my images with
the collection module to show me only images with this tag. Using the
presets button I can save a preset to the collection module to be ably
to quickly find the images I need.

Also, to filter finished images from the same trekking trip, I'm using
the green color label. Green means "ready to export" to me, so I've
marked finished images with green (F3-key) and can filter for those
using the collections module, see the attached image.

The collection module allows you to create very specific collections.

Sorry for the late reply.
Yes, it's how I've filtered for jpegs with/without corresponding raws
in the past. As you've stated, it won't help if you want to show B.JPG
*AND* C.RAW. I've misread that in your OP.

So a user can add more than one style and disable one or more once they are

Currently I resolve to apply a minimum style that works most of the time and 
then tweak several modules on top of that but it can be better. Regards, B

Re: [darktable-user] Excellent work

[Matej Martinovic]

Hey,

the settings you apply to each image are stored in the .xmp-file. This 
is located in the same directory as the image itself.


You can reset images from within darktable, either in lighttable mode 
via history stack-> discard or in darkroom mode via the history module 
on the left side. Click on "0 - Original" and then on compress history 
stack.

Re: [darktable-user] Highlight Details

Hello,

Hi All,

I am a recent convert to Darktable, and seem to be battling to find a good way 
to recover detail in highlights. Lightroom does such a good job of it with a 
single slider.

I found this video: https://hooktube.com/watch?v=JF5CFQPgidk but he doesn't 
recover any detail, simply push colour into area's that are washed out... which 
is not what I am attempting to achieve. I would like to see the details in 
blown out cloudy skies recovered. Since I have literally seen this possible in 
lightroom, I am surprise I cannot recover the detail on the same raw file 
within darktable.

Maybe you have all seen this question before, and have some suggestions?

Thanks,

Chris

 That’s good to know, Hennka. Perhaps something else is awry with my 
box. Nevertheless, I’ve now noticed another problem: dt crashes when I try to 
geocode my NEF files by dragging them onto the map. Just for the helluvit, 
could you try to test this on your machine, please?

 When I had first fired-up dt after upgrading, I was greeted by 
a dialogue stating something about performance enhancements being made to this 
version and I could choose to accept them or not. Well, I decided not to 
because things were operating quite well with 2.4.1. Bad choice, my machine now 
chugs and drags along wheres earlier it flew! Question is, how can I engage the 
“enhancements” since the one-time-only dialogue is gone? Either that or, I’ll 
go back to 
2.4.1

Re: [darktable-user] denoising problems

[Matej Martinovic]

Hey,

denoising in darktable is somewhat tricky:

Use the *denoise (profiled)*, set it to "wavelet" and set blend mode to 
"color". This eliminates the awful color noise. Use a *second instance* 
of denoise (profiled), set it to non-local means and choose blend mode 
"lightness". With that second instance i'll usually reduce the strength 
or opacity to my liking to keep some detail.


You can set some presets and have them apply the correct denoising 
automatically.


This info is also available in the manual 
https://www.darktable.org/usermanual/en/correction_group.html, under 
3.4.4.3. Denoise – profiled -> mode.

What can I do to improve the image?

Re: [darktable-user] image information > focus distance

[Matej Martinovic]

It's the distance from the sensor plane of your camera to the subject 
which is in focus. You can see the set focus distance also on the 
distance scale on your lens.

Re: [darktable-user] Darktable on Windows

[Matej Martinovic]

I'm not sure you would benefit from OpenCL. As someone already pointed 
out, you need a somewhat decent GPU to make use of it. Did it work 
before the upgrade to 16.04?


Your overall slow performance may also be due to heat problems. Have you 
checked the temperature of your CPU and GPU? Older laptops get filled up 
with dust. The CPU/GPU reaches higher temperatures and throttles itself.


Windows, btw, is never the solution ;)

I thank you all for your comments.

There's another issue that I thought last night, about changing 
operating systems. I produce some publications, photobooks, etc, with 
a software that I choose only because it has a Linux version. They 
have a windows version, of course, but my books were made in this 
filesystem, with these photo locations. If I change to windows, 
pathnames would not match and I thing I would loose my work.

This only would prevent me to change OS.

Well, I think I could try to go back to 14.04 and use the packaged 
version of dt. Since its an old computer, maybe I should stick with an 
old OS version ?

I always used it from PPA. I understand there is some dependency
that only comes with 16.04. To my knowledge - the only benefit to
use Open CL (if this is your goal) is if the GPU is very fast. I
can use Open CL "GeForce GT 525M/PCIe/SSE2" - I believe 2 GB
memory for the GPU but I have no speed benefits because my GPU is
too old (my whole computer is too old actually). For speed - I use
the CPU. My only benefit for the GPU is to have a real monitor
plugged to the laptop.

I got burned before with AMD...

And with that old computer - I am processing still quite a bit of
pictures (thousands actually) - thanks to DT

For what is worth...

I am using DT on Dell XPS (mid 2011) - this is i7 (gen 2) -
machine 8GB RAM SSD Samsung 512 GB with Ubuntu 16.04.

Compared to

DT on Dell Inspiron (late 2014) - this is i5 (gen 4) - machine
8GB RAM same SSD Samsung 512 GB with Windows 10 64 bit home
edition fully updated.

For now - I am _not_ going back to Windows. And the issue is not
only with DT - everything on windows is much slower. So much so
that nobody at home can stand it most of the time except my
daughter who plays some games on it.

I know I am comparing i5 vs i7 but the windows is 3 years newer
machine (and I have tested it on Linux - live CD and it does
work much better in terms of speed).

Hi Matej,

Yes, I have:

But I still cant get Opencl to work.

In fact, I've been thinking if this slowness may be fault of
these alternative drivers.

Re: [darktable-user] Exported JPG vs. Camera JPG

Hello Johannes,

please do, an in depth tutorial would be nice.  I'm struggling with the 
default presentation of my D610 images and thinkig about investing in a 
color chart by Wolf Faust.

Am 23.10.2017 um 10:20 schrieb johannes hanika:

heya,

this 60D case is really unfortunate. the way we handled defaults in
the past isn't very good.. in a sense that if we now replaced the
apparently broken 60D "enhanced matrix" it'll break history stacks for
all old images.

we should probably store at least a 3x3 matrix in the parameters of
the input profile module such that it doesn't depend on an external
icc file. now if you select an external profile, you'd have to move
the icc file around with your library to be able to reproduce the same
results.

the darktable-chart workflow is somewhat better, because it does store
all required information in the history stack (and it's editable and a
more expressive mapping/lut). so if you are going to create a profile
for a chart.. i'd recommend you do it with darktable-chart as a
preset/style for the colour lut module. i think i should prepare an
extended tutorial how to do this.

cheers,

I shot a portrait with my Canon EOS 60D and noticed that the JPG from

I have a 60D and a 5d mark iii. I can vouch for the fact that the "enhanced colour 
matrix" that is
the default does a poor job with the 60D raws (generally much better with the 
5d3 raws), mostly with
the blues.

Yes that's what I noticed too. If I switch to "standard colour matrix" the 
results are much better.


I found creating my own matrix from a Wolf Faust target worked really well,

Tim Rolph also mentioned the Wolf Faust target but I have to admit that looking at the 
website I don't know what to order. What "Order #" would be the right one?


but ultimately decided that having the additional dependency of having that 
profile present if I wanted
to re-edit the images at a later date wasn't worth it, and I do much as you do: 
use the standard
profile. Sometimes also setting the gamut clipping to linear rec2020 is a good 
option as well.

I don't really get that. Don't you have to create the profile just once and 
then it's done? As the color mapping should contain all colours it shouldn't 
change from photo shot to phot phot, should it? Or would it be needed to create 
a new matrix for every photo shot just like doing a gray card shot for the 
white balance?


I can probably dig up the 60D profile if you'd like to try it.

It would be great if you could lookup the profile. I'd like to give it a try.

Rob

Thanks a lot. Also @Tim Rolph.

Best regards
Thomas

[darktable-user] Send files to trash is not working properly

[Matej Martinovic]

Hello,

if i want to trash a file, that is located on a second hdd and not my 
/home folder (which is on a ssd), i get an error message stating that 
the file cannot be moved to trash.
"Unable to find or create trash directory for 
/media/myuser/path/to/file/on/hdd"


I can trash files from my file manager without problems, but i'm not 
sure if it's solely a problem with darktable. Trashing files within 
darktable that are on my /home works as it should.


Could there be a problem with my /etc/fstab?

I'm running darktable from git under fedora 26.
