Since my ancient copy of Adobe Lightroom 6.0 is no longer playing nice with macOS Big Sur, and I have been impressed with the discussions I’ve seen from the darktable developers, I decided it was time to switch to darktable for real. I’m still just wading into these waters, so please, if you need to say “RTFM”, feel free.
My background: 40 years as a software developer. 35 years as an advanced amateur in photography, mostly freelance motorsports photography. I learned exposure by shooting slide film, so the transition to digital and its unforgiving clipping characteristics was not a big deal. I have read most of Dan Margulis’s books and understand how to use the principles in them. I have prepared color photos for press (and won awards from the car club community for my work) when a “big” monitor was a 17" CRT at 1024 x 768. I was a diehard Lightroom user from the first public beta until they switched to the subscription model.
First - kudos to all the developers for an astoundingly capable DAM and photo editing application. This is the first Mac app to date which lets me use both of the GPUs in my Mac Pro (trashcan).
Second - I was quite fond of using LR with a 2nd window displaying the image I was working on, full size on my 2nd monitor. I’m happy to find that I can still work that way.
Third - there is a whole lot of control here! If anything, there’s too much control (more about this later). But for sure this isn’t some “Lite” or dumbed-down app.
Fourth - the online (English) manual is a great piece of work, and does a great job of explaining the “why” of some of the pipeline modules. It is a reference manual, though, and needs a quick-start tutorial to go with it. Maybe even a “darktable for LR refugees”. I’m old enough that I prefer to read, rather than watch videos.
User interface observations, nits, and feature requests:
-
PLEASE, add a way to display the pixel values under the cursor! I lived by that with other applications for literally decades. It’s the thing I miss most when using DT. (Again… if I missed a clue about it, drop me a hint.)
-
I find the sliders difficult to use quickly and accurately with a trackpad. Double clicking the slider to activate the keyboard shortcuts causes the slider to be set somewhere before being reverted to its default setting, and that causes the image to get reprocessed and redisplayed. If a better way to activate the keyboard shortcuts for a slide already exists, please tell me! LR activated the key shortcuts for a slider when my mouse merely hovered over it. I would love to see that feature in a future release.
-
I appreciate the flexibility the “eyedropper” controls give by using a region with handles, but I find that awkward when (e.g.) setting white balance. Just let me click once on the neutral/highlight/shadow please! I would prefer a choice between a fixed-size “spot” and a user-defined region. Or just a spot.
-
Scrolling the lighttable view via the trackpad moves in larger increments than I would expect. I have gotten quite accustomed to just a two-finger swipe to scroll by part of a page in many, many Mac apps. Doing that from the top of the lighttable when hundreds of photos are on it usually puts me 2/3 of the way down the list.
-
The handle at the bottom of the filmstrip is impossible to use with the macOS Dock in auto-hide mode. I am not going to disable auto-hide; that would burn up valuable screen real estate.
-
I usually edit with highlight/shadow clipping display turned on. I find that some adjustments don’t reactivate the clipping display, and it has to be cycled off and on to reappear.
-
The sheer number of modules listed in the develop pipeline is overwhelming to this new user. The display-referred and scene-referred presets help, as does the user preset editor, but it’s still a bit overwhelming. I found that when I first set up my own workflow preset, the pipeline display didn’t update immediately to show only the modules in my preset.
-
A suggestion re workflow presets: the “Beginner” workflow still shows too many modules, and puts multiple options for doing the same thing in the pipeline. A true beginner workflow needs to be simpler. Should a beginner really have both filmic rgb and base curve modules available? Pick one or the other. Perhaps offer multiple “Beginner” presets, e.g. one for LR refugees like me. Are there online repositories for user presets?
-
I’m finding filmic rgb to be extremely powerful, but not yet intuitive for me.
-
I noticed Richardson-Lucy deconvolution was available through a Lua export script; could it be made available as a module, or an option in the sharpen module? I was quite impressed when I saw how well it worked in Raw Therapee.
I am willing to contribute a modest amount of my own coding labor into DT, but I’m afraid user interface design is not my strength. I’ve done enough UI implementation and cross-platform coding to appreciate how difficult it is to get everything working seamlessly on one platform, let alone cross-platform.
Anyway, thanks for an outstanding open source application. I look forward to being part of the DT community, and I hope a contributor to it as well.
