It tries to fill the gap between the many excellent existing free raw converters and image management tools (such as ufraw or f-spot). The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. the user will always be able to interact, even if the full resolution image is not yet loaded. . All editing is fully non-destructive and only operates on cached image buffers for display. the full image is only converted during export. The frontend is written in gtk+/cairo, the database uses sqlite3, raw image loading is done using rawspeed, high-dynamic range, and standard image formats such as jpeg are also supported. The core operates completely on floating point values, so darktable can not only be used for photography but also for scientifically acquired images or output of renderers (high dynamic range). Notice that the Depend: section says: libexiv2-27 (>= 0.27.5-1.1). FWIW, The system I'm trying to install on has Debian testing (bookworm), but both the Debian Next and Debian 11 darktable packages failed to install with the same dependency error. darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
Re: [darktable-user] darktable 3.8.0 released
Based on the release notes and the new documentation, this looks fantastic. Thanks to everyone that contributed. I'm looking forward to trying it out.

You are strongly advised to take a backup first. Important note: to make sure that darktable can keep on supporting the raw file format for your camera, *please* read [this post](https://discuss.pixls.us/t/raw-samples-wanted/5420?u=lebedevri) on how/what raw samples you can contribute to ensure that we have the *full* raw sample set for your camera under CC0 license! - Almost 3915 commits to darktable+rawspeed since 3.6 - 571 pull requests handled - 265 issues closed ## The Big Ones - The keyboard shortcut system has been entirely reworked and extended to allow you to control darktable with other devices, for example, MIDI devices and game controllers. Standard keyboard/mouse shortcuts can now make use of mouse movements (horizontal, vertical, diagonal) as well as multiple button/key presses and short or long presses/clicks. Please note that any shortcuts you have previously created are not transferred to the new functionality and will need to be redefined in darktable 3.8. - New diffuse or sharpen module, allowing you to simulate or to revert diffusion processes to reconstruct images from lens blur, hazing, sensor low-pass filter, or noise. It can also be used to simulate watercolor smudges, increase local contrast, simulate blooming or apply surface blur. Special rules can be defined to specifically diffuse across or along edges, as well as to avoid sharpening or blurring them. - New scene-referred blurs module, to synthesize motion and lens blurs in a parametric and physically-accurate way. This module allows you to define the motion path or the lens diaphragm and then generates the corresponding blur. - Perspective correction module has been renamed to rotate and perspective and now allows you to manually define correction settings by drawing lines or rectangles on the image (replicating keystone correction functionality from the deprecated crop and rotate module) - Added support for multiple images in the print view. The page can be filled with multiple areas, each of which can be moved around and placed on the page with the ability to snap to a grid for precision. - A new LMMSE demosaic algorithm has been introduced. This algorithm is particularly suited to high ISO and/or noisy images. - The composition guides from the crop module are now available globally and no longer require the crop module to be activated. - The Canon raw CR3 format is now supported (see list of supported cameras in the section below). This support is provided by LibRaw and requires at least exiv2 version 0.27.4 with BMFF support activated. - The color checker profiling tool, introduced in darktable 3.4 as part of the color calibration module, is now normalized patch-wise in exposure to discard the effect of uneven lighting and fall-off when shooting color checkers hand-held and on-location. This robustly decreases the residual average dE after calibration and noticeably helps to recover natural dark blues while preventing yellow shifts in highlights. ## Other New Features And Changes - The denoise (profiled) module
[darktable-user] Windows or Linux?
My understanding is that darktable started life as Linux software, but I know it is now available on Windows as well. I have the flexibility to install darktable in Windows (10) or Linux (debian). My assumption was that darktable would be more reliable and the user interface would work better on on Linux, since that's what is was design for, but I realize that might not be true. Which platform (Windows or Linux) will give darktable work better on? darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
Re: [darktable-user] Can I invoke an external programme from DarkTable
I'm also currently using Lightroom (5.7) and considering moving to digicam and darktable. I've played around with both (on Windows 10, although I'm considering trying to run them in WSL), but haven't been systematic enough to know what I will miss from Lightroom, so I would be interested to hear your thoughts on what is the loss of functionality and usability for digicam (and darktable too) compared to Lightroom. thanks, Peter Canning PS: If the digikam discussion is too off-topic for this list, feel free to reply to me directly. On 6/21/2020 7:52 AM, tony Hamilton shaky.start-at-ntlworld.com |darktable-user| wrote: You are correct: the primary value of PS (for me) is in its layering functionality. This makes it very adept at some specific tasks - in addition to its masking functions (which appear to be easier to use/understand than those in DT) it can, for example, expertly complete such complex tasks as changing the sky background of a photographically interesting tree. I don't know enough about other image editing applications (especially DT) to know if this effect is achievable as accurately and as (relatively) easily as it is in PS ( and I use CS6, now a very old version) - but I suspect not. The LR->PS->LR round trip is very straightforward, having specified PS and it's location as a suitable 'external editor' in LR settings. One can then invoke that editor from LR, at any point in the work flow within LR, very simply (menu item, mouse selectable or function key). LR passes the image file to PS which opens it in Adobe Camera RAW if it is a raw file; if the image is jpeg or TIFF, it is passed in 1 of 3 optional states: a) a copy of the original image with LR edits included, b) a copy of the original image untouched by LR, or c) send the original image (not a copy) untouched by LR. After editing the file is saved as a TIFF in PS and that editing window is closed. The PS-adjusted image is then optionally stacked with the 'original' In LR and editing can continue. Even though LR does not support layers, if the image is not flattened in PS before saving, the 'knowledge' of the layers is maintained by LR and can be exploited in a subsequent invocation of PS. All in all LR and PS are closely integrated - not seamless, but very close. I would be very satisfied if I could find a similar level of integration between DT and PS - or even GIMP, as that would allow me to work within Linux. The only reason I currently use Windows is because I use LR and PS and they are adequately integrated. My preference to use iMatch as a DAM could be reduced to using Digikam in Linux - but there would be some loss of function and usability (in my opinion).

Is there a way to invoke any 'external' programme while working in DT ? Short answer: no (or 'not yet') Long answer: DT has some local retouching tools (like cloning and healing) and a very powerful masking system that allows you to apply any tool to very specific portions of the image. This usually negates the need for an external program like Photoshop for most people. Yes. My first thought on seeing the original question was "yes, but why? this is DT not LR". I'm a Linux user and not conversant wit those windows tools in detail but it occurs to me that what PS is doing is 'layers'. Is that the specific requirement? As you say, Guillermo, DT's tools are powerful. I have a number of books that notionally describe working in PS but I have no problem mentally translating them to work in DT. I'd like to ask the OP about how the LR-PS-LR process re-imports the image back into LR after PS has tweaked it. darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

[darktable-user] How to compare photos side-by-side
I'm a long-time Lightroom user that has been considering switching to darktable since Adobe switched to subscriptions, and I finally decided it was time to give darktable (2.6.0 on Windows 10) a real test drive on a set of wildlife photos from a morning hike. I've completed my initial round of culling, and my next step is to select the best of the rest so I can process and publish them. In many cases I have a sequence of photos of the same subject, and in LR I would use the compare view to look at pairs of images side-by-side, switching between zoom-to-100% and zoom-to-fit, to find the best of the sequence and give it a rating. I haven't found anything similar to LR's compare view in darktable. Is there some way in darktable that I've missed to compare two photos zoomed to 100%?
