if you downgrade, you may have problems with your library.db being
incompatible.  So make sure you make backups.

sounds like your xmp files are somehow not the same as contained in
library.db.  Why don't you try re-importing your files with an empty
library.db (move your present library so you have something to fall back
on if you have other problems).

and I might be all wet, but ...

[darktable-user] core options optimization

[I. Ivanov]

Hi Guys,

I know my system is quite old but I am trying to squeeze as much life 
out of it as I could. I am attaching screen shots from the core options 
and the os specs.


Can you please advice if I can set them better? I have doubts my 
settings are the best for my system specifically how much memory I 
am allocating.


I read https://www.darktable.org/usermanual/ch08s02.html.php My 
impression is the default settings are for systems with around 4GB. I 
have 8 so I tried to increase the values. But I may be doing more harm 
than good.


Thank you,

B

Re: [darktable-user] Compile fails (librawspeed)

[Kristian Niemi]

Sorry, I only set LANG previously. When I also set LC_ALL to sv_SE.utf8 it
worked.

So, doing "cmake ../ && make" works. Great.

...

And, oddly enough? So, now, does "rm -rf build && ./build.sh" too. :-S

...

Huh. Started with a fresh terminal, locale then set as follows:

LANG=sv_SE.UTF-8
LC_CTYPE="sv_SE.UTF-8"
LC_NUMERIC="sv_SE.UTF-8"
LC_TIME="sv_SE.UTF-8"
LC_COLLATE="sv_SE.UTF-8"
LC_MONETARY="sv_SE.UTF-8"
LC_MESSAGES="sv_SE.UTF-8"
LC_PAPER="sv_SE.UTF-8"
LC_NAME="sv_SE.UTF-8"
LC_ADDRESS="sv_SE.UTF-8"
LC_TELEPHONE="sv_SE.UTF-8"
LC_MEASUREMENT="sv_SE.UTF-8"
LC_IDENTIFICATION="sv_SE.UTF-8"
LC_ALL=

Then build.sh fails. If I export LC_ALL="sv_SE.UTF-8" it works. Great! Case
closed.

Thank you for taking the time to help out, Roman!

Kind regards,
Kristian

Hi,

It's jsonschema 2.5.1.

Hmm. I set LANG to C for debugging purposes, previously. I'll set it back
to sv_SE.utf8 now and see if it matters.

Kind regards,

Which version of jsonschema is that?
Also, is is LANG env variable set appropriately?

Re: [darktable-user] Compile fails (librawspeed)

Hi Roman,

Thank you for your, as always, swift help.

Doing as you suggested actually gets me a bit further than a "rm -rf build
&& ./build.sh" (which led to the previous last lines I emailed about).

A "cmake ../" and "make" gets me as far as 92%, but then fails with
---
[ 92%] Checking validity of noiseprofiles.json
usage: jsonschema [-h] [-i INSTANCES] [-F ERROR_FORMAT] [-V VALIDATOR]
schema
jsonschema: error: argument -i/--instance: invalid _json_file value:
'/home/krisse/dev/darktable/data/noiseprofiles.json'
data/CMakeFiles/validate_noiseprofiles_json.dir/build.make:58: recipe for
target 'data/CMakeFiles/validate_noiseprofiles_json' failed
make[2]: *** [data/CMakeFiles/validate_noiseprofiles_json] Error 2
CMakeFiles/Makefile2:7247: recipe for target
'data/CMakeFiles/validate_noiseprofiles_json.dir/all' failed
make[1]: *** [data/CMakeFiles/validate_noiseprofiles_json.dir/all] Error 2

Holding your breath definitely won't help ;-). But there's work ongoing:

https://github.com/darktable-org/darktable/pull/1327

There's still a long way to go (code-wise and acceptance-wise), but it's 
probably the first time there's hope that a port attempt be eventually accepted.

Re: [darktable-user] What do the sliders of the local contrast tool actually do?

[Ari Torhamo]

Hi Rafa,

Thanks for the tip. I tried that, and it brings interesting results. Not 
very easy to interpret, though, when the aim is to understand how 
'contrast' and 'detail' work together and affect each other. Experience 
will probably help. Anyway, undoubtedly a useful tool to have in the 
toolbox in many situations.

Hello,

I've been trying to find out what the different sliders on the
local contrast tool actually do in Darktable. There are three
sliders and the working of the first one seems obvious; it adjusts
the radius (in pixels?) of the area the other sliders affect on.

The contrast slider doesn't seem to do anything if the detail
slider is in zero position. In other positions both sliders change
contrast, although differently, the detail slider having a
stronger effect. I'd like to know what these two sliders actually
do. I've been testing and observing their working on different
photos, but I still feel that there's too much trial, error and
confusion involved in using them.

I'm not asking for mathematical formulas (although they might be
interesting, if I'd understand them), but rather a clear
explanation in plain English. The explanation on the Darktable
user manual is very vague, and a good amount of googling didn't
help either.

I hope someone in the know can take the time to answer this.
Perhaps the answer could be used to improve the user guide. Thanks
in advance!

hi,

sorry i don't have an english explanation, only the formulas.

this module enhances local contrast by using
``Unnormalized bilateral filtering''
as described in
http://people.csail.mit.edu/hasinoff/pubs/AubryEtAl14-lapfilters.pdf
(the rest of the paper is implemented in a branch).
Are you sure that paper isn't about the wave functions of quantum 
mechanics? ;-)

the detail slider is mapped to the amount the difference to the base
image will be multiplied by.
Difference caused by what?  Multiplied by what? Sorry, I'm sure it's 
just me, but I don't even know what refers to what in the above sentence.

the backend uses the bilateral grid.

Suddenly the veil was lifted and everything became crystal clear...

Thanks for trying. I'll just push the sliders around and try to come up 
with something that looks good :-)
