[darktable-user] Re: [darktable-dev] Resources for beginners / newcomers
Dear All, (I had sent this to the developers' list by accident, but as Bruce has pointed out, it should be here, on the users' list. My apologies.) There have been a number of questions from newcomers, which is, on one hand, great (means user base of darktable is growing), but it also means that people on this list keep answering the same questions. Therefore, I'd like to suggest a number of resources: - the darktable manual: unfortunately, Google may still bring up links from the old, outdated manual. The new one is linked from the resources section of the darktable.org page, but here is the link again: https://darktable.gitlab.io/doc/en/ (also available in other languages) - darktable blog and news: check out those sections on darktable.org, as announcements and descriptions of new features often appear there before the manual is fully updated: https://www.darktable.org/blog/ and https://www.darktable.org/news/ - Google (or your favourite search engine): please use it. Chances are, you are not the first person to ask. This saves time for you, and also effort on the other side (those answering). A neat trick for Google: if you enter the following search expression: site:darktable.io filmic the search will be restricted to that site (obviously, works for other sites as well) - Facebook: there's a group at https://www.facebook.com/groups/darktable/ - pixls.us: this is a great site about open-source apps for photography and graphics. There are articles (https://pixls.us/articles/) and also a forum with a darktable category (https://discuss.pixls.us/c/software/darktable/19) and posts tagged with darktable (https://discuss.pixls.us/tag/darktable). Many of the developers hang out there, so you can get great help (but search first, please!), take a peek at coming features, learn about the technical details. To ask how to process a picture, just post it in the 'Play raw' category (don't forget to set a licence that actually allows others to play with your image - you'll see a reminder when you post!). Some highly recommended first reading: https://discuss.pixls.us/t/darktable-3-0-for-dummies-in-3-modules/15849 and (maybe later) https://pixls.us/articles/darktable-3-rgb-or-lab-which-modules-help/ Videos: - all the stuff by Aurélien Pierre (one of the core developers), e.g. https://www.youtube.com/watch?v=vP5m1YmSRw8 (but check out his theoretical/technical videos as well, you'll learn a lot!). Also, on the (yet unreleased) version 3.2, especially for people coming from other tools: https://www.youtube.com/watch?v=yod6iH4qJEw - Bruce Williams has detailed tutorials: https://www.youtube.com/user/audio2u - Hands-on videos from Boris Hajdukovic: https://www.youtube.com/user/s7habo - rawfiner (another of the devs): great videos on noise reduction https://www.youtube.com/channel/UCEz-0EYZTx03UdQszbL8xDA - Rico's videos are also popular: https://www.youtube.com/channel/UC126kKAgMILMnVIi7HvQGlw Please respect others' time and do your homework before you ask.

You can extract the colour matrix into an ICC, and put it in the input profiles directory (I'm not at my computer, please check the manual), and select it in the input profile module. If the DCP also contains curves, you won't be able to use those. RawTherapee and probably ART provide better DCP support.

I'm glad you find it useful. I read somewhere or saw a video that said you could play with the noise reduction applied at the different detail levels, but you really had to raise the strength for the settings to be effective (it may have been this video from rawfiner, one of the developers, but I do not have time to re-watch it now: https://www.youtube.com/watch?v=7ZhbeXpx2W8). Someone (I think on discuss.pixls.us) has suggested an inverted U shape to leave fine details alone, so you may try that. I'm partial to my version, but we have different tastes, and possibly the type of camera also matters.

The good news is, if OpenCL is disabled, it cannot cause issues (the bad news is, you miss out on performance; with a second-hand NVidia 1060, my 12-year-old machine is still usable with darktable).

Re: [darktable-user] Leaving a module to conplete an operation?
I really don't understand this confusion. (Apart from the fact that some people did not seem to realise that 'perspective correction' is a separate module, different from the keystone adjustment in the crop module.) In all the modules, the effects of the current setting are visible immediately; is that not the case? Leaving the module only means that you hide adjustment options for the modules' parameters and turn off any mask display if currently shown (and, in case of crop and perspective correction, you also hide the area that's outside the selected crop rectangle, because it'd be a waste of screen estate to show them). For crop and perspective adjustment, the crop rectangle is visible while you adjust the module's parameters, highlighting the part that will be kept when you leave. When you close the module, the area outside said rectangle is hidden, but no data is actually discarded; you can always to back and adjust the parameters (crop, rotation etc.) as you wish. With crop, there's the keystone tool, which is a bit special in that it requires you to click OK to 'commit' the adjustments. If the image was continuously updated (applying the parameters set by dragging the control points immediately), the control points *themselves* would be moving all the time, which would make editing a nightmare.

Those are INPUT profiles (e.g. for cameras and scanners). Anything under /home/ is only available for the given user. /usr/share is shared files, shipped by your Linux distribution, managed via packages /home/user/.local/share/ICC - user-level, but not darktable specific. /usr/local/share is also shared, the root user can place unmanaged files (not coming from packages of the distro) there.

Personally, I've copied them to a shared but user-writeable directory, and load them using dispwin when launching darktable, since there was a time when I had issues loading them via the nice GUI config tools (probably caused by my lack of understanding), like this: dispwin -I "/use/an/arbitrary/path/that/you/like/dispcalGUI/storage/HP ZR22w 2015-10-11 D6500 2.2 M-S 3xCurve+MTX/HP ZR22w 2015-10-11 D6500 2.2 M-S 3xCurve+MTX.icc" I've put this into a shell script, which is invoked by my other shell script that loads my self-compiled darktable (dev version).

The resulting curve was applied at the pixel level (all pixels with a given value were affected the same way, without taking their surroundings into account). To replicate the same behaviour, you don't need the mask: select the 'simple tone curve' preset from the tone equalizer (this disables masking), switch to the 'advanced' tab, hover over the image, and start scrolling up and down to adjust brightness. That's pretty simple to use, I think. You could also use one of the other curves, too. It's important to understand what the tone EQ mask achieves. By using the mask, you establish the *average brightness level of each part* of the image, and then raise or lower the brightness of *each part* (it's still not completely local: all areas of the same average brightness will be treated the same way -- you can apply further masks, just like for any other module, to change that). This difference is very important: it allows you to keep local contrast. That is, if in a relatively dark region you have a few brighter details (say, in the midtones), raising the brightness of the dark *pixels* (whether using the zone system, the tone curve, RGB curve, base curve, or tone EQ without masking) the midtone pixels will be less affected (or not at all): the brightness difference decreases, contrast is lost in details. With the mask, all pixels in that region are affected the same way: the midtone pixels in a dark area will be brightened along with their surroundings, and contrast is kept. If you use the tone EQ to compress the dynamic range (global contrast), the same midtone pixels, in the middle of a bright area, could be darkened, maintaining local contrast intact; with traditional curves (and the zone system module) the midtone pixels would be either brightened or darkened everywhere the same way. The 'zone map' of the zone system module is actually misleading, as it implies the module really divides the image into areas based on brightness, and then acts on the areas, but it does not actually do that.

You may not need to tag them. Try this: On the lighttable, using the 'collect images' module => 'hamburger' (presets) menu -> portrait, landscape, or square.

All this SQL magic makes sense only if the database actually stores those fields. Are you sure they're there?

Because if none, then there's no need for direct SQL filtering.

You're right, there's no way to filter based on the camera's rotation sensor. But we do have something better, that takes cropping into account, too.

Since they both say 3.4, and in fact *are* for 3.4, the question was valid and the answer was just as wrong as arrogant. https://darktable.gitlab.io/doc/en/index.html is 'old' in the sense that it's the updated version of the 'old style' manual. Nevertheless, it has been updated for 3.4, but is the last such update. It is available in multiple languages. https://www.darktable.org/usermanual/en/ is the new version, and that is the format that will be used in the future. It has fewer screenshots (which tend to change often, and are therefore hard to maintain). Finally, https://darktable-org.github.io/dtdocs/ is, as far as I know, the latest and greatest, updated for the development version (even though its version number still says 3.4). It's automatically generated from https://github.com/darktable-org/dtdocs The latter two are currently available only in English.

Collect images -> capture details -> aspect ratio I don't know any more direct way. You could save the few portrait aspect ratios that you use (those less than 1) as a preset to the collect images module (combine them with 'add more images'), start with that, and filter for film roll or folder with the 'narrow down search' operator. Note that the ratios are not necessarily exact, and not even stable: a portrait-mode 16:9 image from my LX7 showed up as 0.5 before I opened it, and changed to 0.6 after opening it (probably because the first ratio, 0.5, came from rounding/truncating the side ratio of the JPG preview, as opposed to the raw pixel numbers that resulted in 0.6).

So, it is my understanding that you physically remove images without removing them from darktable's database. In that case, you're inviting trouble. When you're done (exported everything etc.), you should select the images and click 'Remove' (not 'Delete'!!!). Removing them before moving the files will keep your database clean.

Re: [darktable-user] Rawtherapee seems to be sharper than Darktable, doesn't it?
The darktable image is darker. Perceived sharpness also depends on contrast. RawTherapee can apply a bunch of tricks (capture sharpening, dual demosaicing) that darktable cannot do (dual demosaicing is on the master branch, though). I see some CA in the darktable JPG that I don't see on the one from RT, and the applied lens correction isn't the same, either. Noise levels and sharpening are also different. You may have more luck posting it on pixls.us as a PlayRaw. https://discuss.pixls.us/c/processing/playraw/30 Please make sure to include a permissive licence that allows others to download and modify your image and then upload ('publish') their version ('derivative work').

Does this capability exist at all? No, since in JPEG (I guess you're referring to JPEG, but the same also applies to PNG) you cannot set the desired output size: you set the compression parameters, but the resulting file size also depends on the content. This is contrary to music or video compression, where you often set a desired bitrate (average or fixed), and the compressor tweaks the compression parameters (e.g. quality settings) to achieve it.

Re: [darktable-user] exporting to Tiff
Hello, You may want to try signing up on discuss.pixls.us, which is now the recommended way to interact with the community, including the developers. https://www.darktable.org/contact/ mentions the mailing lists as 'last resort'. Make sure all your applications are properly colour managed. darktable has a utility, darktable-cmstest, that can check your display profile. There are quite a few ways this can go wrong. You should set a display profile in your desktop environment, open a new command shell, and run darktable-cmstest. Then also check the Gimp. In Edit -> Preferences -> Color management, set 'Image display mode' to 'Color-managed display', and, just to be certain, you may want to set the 'Monitor profile' to a specific file. If everything is fine (as reported by darktable-cmstest), you shouldn't need that (note that the specified profile is only used if 'Try to use the system monitor profile' is unchecked, or if it fails to read the profile from system settings. (It might be a good idea to back up your ~/.gimp-2.8 (or whatever version you use) directory, and then reset Edit -> Preferences -> Color management settings before you try setting a new profile. There are two ways to determine the display profile; the 'X atom' and 'colord'; darktable-cmstest will check that they are set to the same value -- and that's the one Gimp should also use. Then check what profile you use for darktable export, and using which profile Gimp interprets the exported file. It's easy to sign up for discuss.pixls.us, and there you are allowed to share images (e.g. screenshots), which could make this investigation easier.

Guillermo has already answered that, but there's a non-trivial feature (documented, but not realised by many): darktable, by default, saves the history stack into the exported JPG, and it can actually load the history stack from such a JPG. The procedure is the same as with the XMP, but you need to change the selector in the Open dialogue from *.xmp to 'All files', and select the JPG file. Also, if you're after a 'look', if perfectly fine to apply any history stack to any image, even if it's a different camera -- just reset the input colour profile to use the values for your camera.

I think these are two different aspects of applying presets. The '%' marker influences >>>which images<<< a preset is applied to. E.g. if I set focal length to '%', it means it'll match all focal lengths. Whereas, if I understand correctly, Michael wants to achieve that >>>only certain settings<<< of a preset would be applied (e.g. in lens correction, set the module parameter 'corrections' to 'only distortion', but leave all other parameters as they are read from the camera or at default values; for filmic, set 'preserve chrominance' to 'no' (or whatever someone may wish to use), but still let filmic auto-apply all the other settings, some of which are calculated from exposure settings -- but not if a preset is used).

This is described here: https://www.darktable.org/usermanual/en/special-topics/program-invocation/darktable/ I'm not sure if it is possible to: - send a file to an already open instance of darktable; - set the data.db file (which stores your tags, styles, presets...) separately from your library (you'd probably still want to create and reuse such styles and settings, even if the library is only stored in memory).

If using the scene-referred workflow, Fuji cameras are known to require more exposure correction than the +0.5EV applied by default; you can create your own exposure preset and have it applied automatically -- see https://www.darktable.org/usermanual/en/preferences-settings/presets/ Also, if your camera applies some kind of dynamic range compression (basically: underexposing to save highlights, and boosting shadows and midtones in-camera for the JPG preview), you'll have to correct for that; with the modern workflow, you'd apply additional exposure correction and use filmic to bring back the highlights as usual.

Re: [darktable-user] Tone Equalizer, Mask
Tone EQ allows you to apply different exposure compensations to different parts of the image. You can achieve a similar effect by creating several instances of exposure, e.g. one without a mask, so set overall brightness; one with +1EV to lift the shadows, with a parametric mask; and one with -1 EV to tame highlights, again with a parametric mask. Tone EQ basically does the same: it blurs the image to create a 'mask', and then allows you to specify what exposure compensation to apply to which masked range. So it's like automatically creating a mask for -8 EV (dark shadows), -7 EV etc., up to 0 EV (white), and assigning each of them to another instance of the exposure module. darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

Some modules may produce negative pixel values, and some code (especially OpenCL-accelerated computations) cannot deal with that. Though, when this happens, I usually see it in the editor, not just when exporting. You may try: - turning on the option 'clip negative RGB from gamut' in 'color calibration', if you use that module - using 'black level correction' in 'exposure' (the scene-referred workflow comes with a default of -0.0002; you may experiment with numbers between 0 and, say -0.01 -- setting too large a number will produce faded blacks) - if you use large contrast or saturation boosts, reducing them - toggling modules one-by-one to find the culprit Also, do you use any styles that are added automatically in the 'export' module? It could explain why you can edit but not export. You may have a better chance of getting help at https://discuss.pixls.us/c/software/darktable/19, where it is much easier to attach images and sidecar files. Many of the developers are there.
