Description

I've started using Darktable for a short while after a number of years with Adobe Lightroom. I've been extremely impressed with the functionality and performance of this program.

The one major shortcoming that I see right now, is the lack of functionality in terms of importing and culling lousy photos. I'm sure that many, if not most, photographers take numerous takes of the same shot with the intent of obtaining the perfect shot - tack sharp, eyes open, correct exposure, etc... - and deleting the rest. I had a very efficient and productive workflow in Lightroom, using a combination of the "survey" and "compare" tools. I'd love to see these features added to this software.

'Survey' shows only the selected photos and automatically tiles them such that the sizes are maximized. I have a filter set up that hides photos tagged as 'rejected'. I open a 'set' of similar photos, and all photos are displayed on the screen. The obvious rejects are tagged and disappear from the view. The view dynamically changes as the number of photos keeps going down. This increases the size of each photo making it easier to pick out the rejects. Then, once I've gotten rid of all the obvious rejects, I can switch to the compare tool which just pulls up 2 photos side by side, zooms them together, etc. so that I can make a detailed comparison between the two.

This approach lets me go through hundreds of photos in 15-30 minutes or so.

This is what our star rating system is for. In lighttable mode you can limit your view to unstarred, 1..5-starred, and rejected. By mousing over relevant pictures you can change their ratings.
I think this goes at least some way towards doing what you're used to with the competition.

Please try it and let us know.

I guess the request is more about a dynamic zoom setting. I kind of like the idea to have a special setting which always tries to fit all the images into the lighttable (maybe MIN). I have no real idea how to integrate that into the GUI though. It somehow has to work with the slider/textbox in the bottom panel.

#8673 is a related issue.

Side by side comparison with parallel zoom is an extremely good idea, IMO.

This would also fit nicely into the snapshot comparison functionality: Being able to switch between wiper/slider mode and side by side comparison.

Side-by-side comparison code could then be used in two places. :-)

I would also like to be able to "shoot" to cull. So a mode that allows me to just click on a picture to set its rating to reject and make it disappear.

James,
Thanks for your thoughts. I'll give that a shot and hopefully, as you've said that might be a comparable workflow.

From the top of my head, I do not recall that you can only show specific pictures in lighttable mode. I've found that the main advantage of this feature is that it operates on a specific selection set. Only the selected images are displayed - which allows for the maximum zoom - and with a filter to hide rejected photos, the remaining photos increase in size making it easier to discern the increasingly subtle differences. As I get down to the last couple, this is when I use side-by-side compare.

From my own personal experience, I'd see #8673 as a related issue more in the sense that they are both tools that I'd use for sorting the keepers from those I just delete off my hard drive altogether.

I'll play around with your suggestion and will advise.

Yes - exactly. But only for a subset of selected images.

I can imagine a mode to realize this feature, that allows for multiple selection of images in the slider in the bottom panel, rather than just a single image (as in Darkroom mode). Which ever images are highlighted are dynamically fit into the window. The competition (?) accommodates pictures with different orientations so that it maximizes the size of each picture even with a combination of portrait/landscape orientations.
When used in conjunction with a filter to hide all rejected photos, as I reject images, they are automatically removed from the selection set (by the filter) and the photos dynamically resize again.

I just started using darktable and also found that I was missing some way to easily select the best image among a set of similar images.

That would seem sane, though I'm slightly worried about the performance (on my system, loading images in the darkroom takes 1-2 seconds, if you'd have to wait 20 seconds to review 10 images, this would not really work).

I can imagine an alternative approach in the Lighttable: Under the "Selected image[s]" section on the right, add a button "Show only these" (or perhaps "hide others"). Clicking that button adds a new rule to the "collect images" section on the left that filters only the selected images. This can probably be implemented using a new "image id" filter, that accepts a comma-separated list of image ids. Doing it like this makes the filter visible and clearing the filter is a matter of removing the rule in the "collect images" section. Additionally, by adding a new rule, any existing rules (like "hide rejected images" automatically stay in effect).

A second component here would be an auto-fit display mode for the lightroom (which should then be selected in the dropdown near the bottom which shows file manager / zoomable light table now).

#7 Updated by Matthijs Kooijman about 5 years ago

After a bit more investigating, I've found a way to make this somewhat work in current darktable:
- Select the images you want to compare
- Give them a color label you aren't using for anything else
- Add a rule to filter on the color label to the "collect images" section
- Select "filemanager" mode, so you can manually zoom using ctrl+scrollwheel

Once you're done with the set of images, select all images and remove the color label again (this will leave the color label in any rejected messages, but you can just remove that one later on after you're completely done).

It's a bit more work, but at least it gets the job done for now.
