[darktable-user] DT 4.6 crash on copy & import

[Frank J.]

Before you upgrade from Darktable 4.4 to 4.6.0 please switch *off* the 
option "/recursive directory/" in the import-dialog window.


If this option is on, DT will freeze when attemting to copy & import.

If you have already upgraded you can't switch it from the gui, because 
the option is in the window that freezes.
Then edit "~/.config/darktable/darktablerc" and change 
"ui_last/import_recursive=TRUE" to "FALSE".

There is an option in the storage part 'look for updated XMP file on 
startup'.

Is it enabled on your Linux system?
Maybe this will help?

No, this Option works every time at the start of Darktable and compares 
all imported pictures for changes (from an other instance?).


This is not necassary when importing *new* pictures (without or with 
.xmp) into the system. There is no old version to compare.

I wish to be wrong, but color management in Wayland may still have a 
long way to go [1].

1. https://gitlab.freedesktop.org/wayland/weston/-/issues/467


Now I get an idea, what the reason for my problems may be.

Because Ubuntu 20.04 on my mashine had some problems on startup, last 
week I decided to do the LTS-upgrade earlier then 22.04.1 is released on 
4th August.

I got DT 4.0 from PPA "unbuntuhandbook".
After upgrade to some new nvidia-drivers, the openCL-Support in DT was 
fixed.


But one of my displays (EIZO) seemed to be out of calibration, it looks 
a bit too green after the upgrade.


I found, that DisplayCAL (3.8.x) is not longer in the sources in 22.04 
because of the dependencies to python 2, with is not longer supported.
But there is a new projekt "DisplayCAL-PY3" porting the code to python 
3. It can be installed with "pip install DisplayCAL" which gives you a 
version 3.9.6, still in progress but works.


The calibration of my new ASUS-display was done in half an hour. But the 
calibration of my older EIZO (has run more then 8000 hours), takes 2 
days with many attempts. Each run with other results, some lookes green, 
some looked magenta, some had bad messages.
Sometimes even the hardware-defined RGB-start-point drifted from one 
attempt to the next.


Each time the result was different, the colors seemed to be "unstable". 
I worried, the last days of my diplay has come.


At least (after a dozen tries) I got a icc-profile that seems to work.

May this problems result from an unstable implementation of 
colormanagement in wayland in Ubuntu 22.04?

Or should I begin to save some money for a new display?
Why does Ubuntu do an upgrade to a system without a stable colormanagement?

Re: [darktable-user] Setting up darktable newly from scratch

[Frank J.]

Hallo Peter,
a new setup and a new import will take long time and maybe the result is 
nearly the same as before because database and xmp-files "should have" 
the same content.

But you will loose your preferences, styles, preview-cache, ...


> some things were .. not copyed

You can use "preferences / storage / look for updated xmp files on 
startup" to synchronize the database with the xmp's.
Changes on pictures, done with a second system (laptop/desktop) will be 
imported.
Switch to "on", restart darktable, switch "off" after sync for a quicker 
start.



> a lot of unnecessary things have accumulated in the database.

Have a look at "history stack" / "compress history".
This will delete all iterations and attempts and reduce the stack to the 
final result.

(This compression will not happen with a re-import.)

To clean up you can manually delete unused styles or unused tags 
(assigned to 0 pictures).

If you're going to do a clean install of darktable 4.0, on which

with the O/S.


To address your specific questions:

  * Is this a good idea? - Don't know since you haven't been more
specific.
  * As the xmp files are also stored on the external drive with the
files, do they automatically fit in the new import? - If you tell
darktable where to look for the files, it will also find the
sidecar files associated with the image files, if they're
maintained in the same folder as the images.
  * Do I have to delete  the config and cache folders manually? - If
you're uninstalling a prior version of darktable, first back up
all your darktable user config and library files (on Windows -
C:\Users\[username]\AppData\Local\darktable), then delete the
folder in Windows before doing the delete/reboot/installation.
  * Off course I can then only import, what I want to have in the new

do you not pull all of a focus-stacking series into one directory?
simply group on the single directory, no lua necessary.
fwiw: that is my workflow.



I import the pictures of one day in one directory.

For grouping manually OR for moving groups of pictures into other dirs 
you have to analyse the time. Sometimes the series are very similar,

The time-gab inside a series is mostly less then 1 second and the time

You select one of the tag-filtered pictures and switch the

of the selected picture as the value (right part).

Yes, that may be useful in some cases.

Hi,
When I import a  series of images straight from the camera (Nikon 
D850, Nikon nef format) in Darktable (scene-referred workflow), the 
images invariably show up as way too dark, as if they are 
underexposed. The histogram shows a big unexposed part on the 
highlights. I am pretty sure though that when I took the pictures the 
exposure is about right (according to the camera histogram). The 
camera-generated jpg is also ok.

What can be the cause of this and what can I do about it?

Kind Regards,

Same effect here.

I use Olympus-cameras, RAW only, correction +/- 0 EV in the Camera.

After importing in DT the default in module "exposure" is "+0.5 EV" but 
this is too dark for nearly all pictures.


I need to use a correction between +1.5 and +2.5 EV for the best look.

This is not new in DT 3.8 but in 3.6 (or 3.4?) with the change to 
scene-referred workflow.


I never compared with camera JPG.

Re: [darktable-user] Focus Stacking

Am 19.04.20 um 20:48 schrieb J. Paul Bissonnette:

Is focus stacking possible in  darktable 3.0.2?
I am using an Olympus OM D E-M5 mark 2 with the latest firmware.
The reason I am asking is that the stacked jpg made by the camera is so
much clearer than the stacked dng file from darktable.
I maybe doing this all wrong I am assuming that focus stacking is a
form of HDR and used the Create HDR button.




Hallo Paul,
I do focus-stacking with the following workflow:

1. Export minimal pre-processed pictures of the stack from darktable 
into a folder.


2. Align the stack with control-points

3. Compose the final picture from sharp parts

4. copy exif-tags to the result (time, camera)

5. re-import the result into darktable for final processing


Examples:

1.
You can crop the pictures but all must habe the same size.
Use copy&paste history stack for all pictures.
You can use 16bit TIFF for better quality.

2.
align_image_stack -v -m -a algn 20200420_0001.tif 20200420_0002.tif 
20200420_0003.tif


Without "-a " the dt-exports are overwritten with aligned versions.
With "-p file" a *.pto is created. That is a hugin-Projekt for manual 
interaction.


3.
enfuse "$@" --exposure-weight=0 --saturation-weight=0 \
  --contrast-weight=1 --hard-mask --contrast-window-size=5 \
  --compression=92 --output=stacked.jpg  algn*.tif



Hugin can be used as a GUI to manually define some 
inclusion-/exclusion-masks for step 3. But most stacking is well done 
without hugin.

Step 3 can be done from hugin-gui.

There is a LUA-Script "enfuse professional" to assist you in this 
workflow. It can be found at:

https://www.multimedia4linux.de/index.php/bildbearbeitung/darktable/darktable-plugin-enfuse-professional

But this LUA-Script will not work for a stack from your "Olympus OM-D 
E-M5 Mk.III" in some cases.


The reason is: Olymus has two modes for focus-stacking

 A. Focus-BKT ON, but Focus-Stacking OFF
 B. Focus-BKT ON, and Focus-Stacking ON

Mode A will take a set auf RAW-Pictures. Beginning with the focussed 
point, moving to the background. This will work with LUA "enfuse 
professional".


Mode B will take a set of RAW and JPG and will process the stacked 
picture in the camera as JPG, as you described.
The first picture will be taken at the focussed point. Then the focus 
jumps nearer and then stepwise to the back.
Before processing this stack with "align_image_stack" in step 3 you have 
to *sort this pictures by focus-point*.
"align_image_stack" compares the pictures pair-wise in the given order 
to find the control-points. The first taken picture will not match with 
the second (nearest). The position of the first picture will be skipped. 
It is possible that the two pictures before and after this position 
don't have overlapping sharp areas when this area is very small.


When using the LUA-Script "enfuse professional" you have no chance to 
manually sort the pictures by "fucus-point" without renaming the pictures.


Therefore I dont use "enfuse professional" but small shell-scripts 
(*.sh) on my Linux-System.


A correction with hugin is not possible when using "enfuse 
professional". The aligned files are in /tmp and will be deletet. No 
chance for taking them for a hugin-project.


Take care not to use lens-correction twice, in darktable and in the 
LUA-Script.


The results auf "align_image_stack" + "enfuse" are better then the 
internal stacking of the camera.

I got some results on stacks where the camera fails to stack.

Good luck.

Hi,
I have a similar workflow.

Import an development of the RAWs happens on a fast SSD, which has 
limited space.

Older projects are moved to a slower HDD as archive.

There are two levels to optimize:

1. Move all images from a folder to a new folder in the archive from

2. When accidently a folder is moved or renamed from outside DT, then 
the foldername in "collect images"/"folders" is stroked thru.
There is a context (right mouseclick) "search filmroll" for a dialog to 
show DT the new location. This will heal the database-entries for all

Re: [darktable-user] Tag hierarchy

[Frank J.]

Don't be confused: The behavior of tag hierarchy is different to the 
bevavior in "collect images / folders".


If you select a root-folder you also see the images from the sub-folders 
without needing a wildcard.

If you select a tag from the hierarchical view, it will only collect

If you want to show images from more than one tag at a time, you have to
type a wildcard ('family|%' in this case) into the text box.

The result: Deleting a row in Table "styles" will also delete all

Thank you Tobias,
It works now and it finds a lot of unused thumbs in the cache.

PS.
The second script 'purge_non_existing_images.sh' worked fine.
It grabbed some Photos that are shown as scull. I removed them manually
with darktable.
It grabbed also some entries in the database that are not visible in

Not really common!
The database contains not only a simple link to the Raw-file in the
folder but also all steps of development in different modules, title,
tags and location.
And the cache contains a batch of previews.

Refreshing a temporarily not available folder (Server, NAS, USB-device)

Hi Tobias,
yes I see the timestamp.
I did some additional tests and found out what I did wrong.

The separator in the date-part of the timestamp should be ":" and not "-".
When I change the "Exif.Image.DateTimeOriginal" in the source-file
again, then remove from DT and re-import, then the timestamp is not only
visible and sortable but also translated to the german date-format.

And: It is used for the $-templates on export.

Sorry for the noise! My mistake.

[darktable-user] Issue with timestamp on export

[Frank J.]

Hi,

for sorting the exported JPGs by year and month, I want to include the
timestamp, when the picture was taken, into the filename on export.

The templates "$(EXIF_YEAR)_$(EXIF_MONTH)_$(EXIF_DAY)" from
http://www.darktable.org/usermanual/ch02s03s12.html.php seemed to be
right for this.
This works fine for pictures (RAW, JPG) that were taken with digital
cameras.

But my DT-archive includes 40 years of work since I scanned all my old
slides with a NIKON Coolscan 4000 ED.

I found, that I have to set for example
 $ exiv2 -M"set Exif.Image.DateTimeOriginal '1978-09-01 00:00:00'" \
   dia_f037_b0[1-9].jpg
BEFORE I import the scanned JPGs into DT.

Not "Exif.Image.DateTime" but only "Exif.Image.DateTimeOriginal" sets
the right timestamp in the database-column "images.datetime_taken" on
IMPORT.

But for this scanned pictures the templates "$(EXIF_YEAR)" etc. on
EXPORT do not work.
It seems "import" and "export" use different exif-time-values.


How can I use the values from the database-column
"images.datetime_taken" for the filename on export?

Hi,

In file "compact-panasonic.xml" the entry


Panasonic
DMC-LX100
panasonicDMCLX100
2.21


Points to:

   panasonicDMCLX100

Add a new -File (or edit in compact-leica.xml?).

Copy model "DMC-LX100" as model "Leica D-Lux typ 109" into the new file.
Copy panasonicDMCLX100 into the new file.

The model must match exactly the text from the exif-Data.

Your changes will be erased with the next update of lensfun. Make a copy.
If it works, give a ticket to the lensfun-projekt.

For a while the name of my new mft-lens did not match excatly between
lensfun-data and exif-data. Editing this files helped my using
lens-correction in darktable until the error was fixed in lensfun.

Hi,
I'm a simple user, not a developer. So I don't really know, what is
planned for the future. But I think the rule is very simple:

As in every other programm with a Graphical User Interface (GUI) actions
from mouse-clicks or shortcuts are targeted to SELECTED objects.
So show the images in lighttable (icon "G" right on top of lighttable)
and select them. Then apply your tag to them.

Assigning tags to images, which are not selected and not even visible in
the gui would lead to unattended results.

It may be usefull to have different tags on the images of a group. How
can this be done when all images of a group gets always (silent in the
background) identical tags?

Deleting directories is more then "settings".

Restore the deleted directories from a backup.
Restore also the darktable-Database from backup:

I had a look on my cache:

That is 2%. I think, that is not too much.
And the .cache/-folder can be excluded in backup.

What ist unused?
A level-3-  or -4-thumb, that will be used with z-key or ctl+z once a
year, is "nearly unused".

But you have more thumbs per level then pictures in the DT-database.
So I think they are orphaned, not only unused.
Your darktable has no knolledge about some of the thumbs.


> Simple way would be to delete all and rebuild all. But I
> think this could be done better.

Shure, maybe you can make it smarter.
But somtimes the simplest way is the best.

The sizes in my cace are:
0: 110 pixel, 1: 225, 2: 450, 3: 900, 4: 1200 pixel.

Begin with deleting level 3 and up.
~/.cache/darktable/mipmaps-d/4/ and .../3/.

You would miss nothing until you screw up your ligthttable to 1 picture
per row or use the z-key (zoom full).
You will have a short delay while DT is generating one thumb.
Only "used" thumbs are generated, no "unused".

Higher level will free more diskspace (per picture).

If you also delete the levels 0, 1, 2 it seems to be better to generate

Hallo,
most the time I'm working with "collect images / *folders*"
rather then "collect images / film roll".
That works better for me. Maybe also for you?

There is an GUI option "number of folder levels to show in list" to
includes some sub-folders (with your HDR ...).

But there is a bug, that DT merges folders when one foldername is the
beginning of another one.
Example:
 ~/pictures/dt/2017/
 ~/pictures/dt/2017_A/

If you select "2017" you also see the pics in "2017_A".

I like to collect with *multiple criteria*, Example:
To see wich files need to get coordinates
"folder = ABC" exclude images "geotagging = tagged".
Then I see only the pictures to drop on the map.

I like to use *wildcards*, Example:

My scanned slides are named "slide_f999_p99.jpg".
Where f=Film and p=Picture in film and 99 = numbers.
To find all scanned slides from one film:
Collect Images: "filename = slide_f123_%".
Then I "select all" and tag filmtype and camera-model, which is not in
the exif-data of the scans.

Hallo,
I set the position in the Map in Darktable.
After export as JPEG your command "exiftool xxx.jpg | grep GPS" shows:

GPS Version ID   : 2.2.0.0
GPS Latitude : 53 deg 58' 22.08" N
GPS Latitude Ref : North
GPS Longitude: 14 deg 8' 47.19" E
GPS Longitude Ref: East
GPS Position : 53 deg 58' 22.08" N, 14 deg 8' 47.19" E

Visible difference is: In your version "E" and "N" (East and North, or
West and South?) is missing.
lat/lon-Koordinates not even need a value, but also a direction.

If you don't use an icon but a command:

DT will start once with an english GUI.

As far as I figured out, ist is not possible in Module "tagging".
But typing also searches for part of the text, not only the begin.

To browse the tags go to lighttable / collect images / tag.
First you see the grouped tags (group|sub-group|tag).
Last group is "uncategorized" where you find single-tags (without "|" ).

We discussed this just a few days ago. See thread:

My (ppa-) package maintainer [1] did all right.

The broken version of lensfun came from another ppa (Gimp ?).

To do (Ubuntu):
- Start synaptic
- search for lensfun
- force version 0.2.8 for this package

Sorry,
can you explain again, step by step?

When I reset "lens correction" it switches back to the default "thoby
fish-eye".
I don't like all my pics having curved lines, so I would like to have
"rectlinear" as default.
When I switch to "rectlinear" then the scale is to big, parts of the
picture are cut off. I have to use "auto scale" to reduce the loss.

Openening the next picture all is beginning from start.

Copy the history stack or "store new preset" always copy also "focal
length", "aperture" and "distance" to the new picture although this are
individual values, which should be taken from the exif-data, not from a
preset.

How can I get "rectlinear" correction with "auto scale" for each new
picture fitting the individual focal/aperture/distance-values of a
pictuture?

I have nearly 50K on my system.
I've no problems with watchching or developing my photos.

Export or creating thumbs is a bit slow because it's only an i3 with
graphics on board, no GPU. A'm working to change this soon ..

Slowest part, I think, is the tagging.
Maybe I'm tagging too much: place, persons, event, ...

For my old slide-scans I tag also film-type and camera-model, cause they
have no exif-data.

DT try to give my some intelligent suggestions while tagging.
For example: when I tag (the german word for) "house-cleaning", DT
suggests to tag also the name of my wife  ;-)
  - really!

DT trys to analyse "pairs of tagging". The database-table "tagxtag" has
2.2 Million entries for my 45K pictures.
Typing in the tag-mask seems to freeze the programm. I have to wait many
seconds.
I would like to switch this feature off for faster work.

As an owner of a Nikon Coolscan I'm very interested in having

Nikon-Filmsanner [2] are still in use, although they are 10 years old,

As far as I know, Filmscanner has a Sensor-Row that move along the
length of the slide.
This seems not to be a "Bayer style sensor" [1].

So (Camera-) RAW is not like (Scanner-) RAW ?

Hallo Michael,
yes, RAW from Nicon Coolscan is not supported.

I think a comment to the website wouldn't change this.
Think about putting an issue here:
https://redmine.darktable.org/projects/darktable/issues

But the developers need sample-Files.
I don't know if they feel the need to work for a "camera-type" that is
10 years old.

I'm owner of a "Nikon Super Coolscan 4000 ED" (firewire).
I scanned more than 8000 slides last year.
Most of them as jpg (8-bit-color). Filesize is 5 to 8 MByte.
The hardware can produce 14-bit-color-depth. Saving this as TIFF need a
lot of disk-space (130 MByte for each TIF).

I use Nikon-Scan-Software now but I'm thinking about VueScan to get RAW
from the scanner.
So I would support your issue to develop the scanner-RAW with the
Darktable-Tools.
Maybe Scanner-RAW ist quite different from Camera-Raw because of the
IR-Color-Channel for Digital-ICE.

That was my start-point.
Look at line 6 of my script:

  # Based on an idea of Antoine Beaupre

I think I made it a bit more comfortable.


> You’re probably right, but I have found that darktable can handle a
hierarchical tag and a simple tag at the same time.

Yes, sure it can handle multiple *different* tags.
Klick on first tag *OR* second tag finds the same picture.

But importing the hierarchy from Shotwell means same tags, not different
tags.

Example:

Shotwell seems to search with "equal".
Tags are:
  "/persons"
+ "/persons/friends"
+ "/persons/friends/John Do"

Klick on "friends" searches: WHERE tags = '/persons/friends'

Darktable seems to search with SQL-"like".
Tag is "persons|friends|John Do".
Klick on "friends" searches: WHERE tags LIKE '/persons/friends%'.
The Wildcard % includes "John Do".

Wrong import:
  "|persons"
+ "|persons|friends"
+ "|persons|friends|John Do"

The SQL-LIKE-Search find more then one Tag pointing to the same set of
pictures. You have to use "SELECT DISTINCT .." to get every picture only
once.


> ... try to find anomalies in the tags.

Ideas:

- Do Ubuntu and Mac have the same coding (UTF-8)?
  In Germany we have some special Characters (ä,ö,ü,ß) that can cause
some trouble. In Scandinavia they have some characters that I cant find
on my keyboard. When transferring the SQL-file (txt) from one system to
another you may use "save as ... UTF-8" in your editor.
Sometimes that is a problem when copying files from Windows (ANSI) to
Linux (UTF-8). Sometimes it is no Problem with characters like
a-z,A-Z,0-9 but often with special/national characters.

- Do you have characters in the tag, that are used in SQL: % ; ' " \
  Darktable may handle this when typing it in the screen.
  But you put it directly into the database.

Hallo Michael,
I had a similar problem last year. I had spend a lot of time for tagging
pictures in Shotwell.
Then I began to use Darktable and wanted to move the tags from the
Shotwell-Database to the Darktable-Database.

I made a python-script to do this in Darktable 1.6.9.
I reported in this mailing-list, have a look at my mail from 2015-11-28:

http://article.gmane.org/gmane.comp.graphics.darktable.user/8392

The pictures must be already imported in DT and in Shotwell with the
same name and path.
It only works for Pictures that has NOT TAGS in Darktable.
Only the tagging will be moved.

Have a closer look to hierarchical tags:
Darktable keeps all steps of the hirarchie in ONE tag.
Shotwell has one Tag for each step, getting longer step by step.
The script takes only the "deepest" tag for a picture.

When you have imported the tags with all steps from Shotwell this may be
the reason for your problems when selecting.
See the examples in the comments in my script.

Get the Script from:
http://www.fotodrachen.de/download/Shotwell2Darktable.zip

Sorry, the "ReadMe.txt" is a "LiesMich.txt" in german language.
But the comments in "shotwell2darktable_tagging.py" are written in
English, ... sometimes.

Hope it helps.

Hallo,
most the time in lighttable-mode I can scroll thru the pics whith the

Sometimes this function is lost and the mouse-wheel controls the slider

How can I set this back to scrolling?

It's very slowly to scroll with arrow-keys.

There are different "times" in Exif.
You have to change the field "DateTimeOriginal".

I'm scanning my old slides and import them to darktable.
The scanning-software sets the date of scanning.
Before I import the files I set the date with commands like:

exiv2 -M"set Exif.Image.DateTimeOriginal '1991-06-18 00:00:00'"

Hallo,
six month ago I had a problem with the 12-40.
http://article.gmane.org/gmane.comp.graphics.darktable.user/8013/

Here is my workarround (written on this list):
http://article.gmane.org/gmane.comp.graphics.darktable.user/8024/

I dropped an issue at lensfun and it was fixed:
 https://sourceforge.net/p/lensfun/bugs/31/
On an actual system, this error should not happen.
