Description

A feature to compare duplicates or even different images side by side would be nice.
Also maybe this could be done in a new window, so multimonitor users could use it too. That way you could continue editing them and quickly alt+tab to the comparison too on one monitor.

I forgot to add:
A tag icon, like the discard tag could be used, also in the filmstrip and lighttable one should be able to see which images are selected for comparing. A key accelerator could show the compare window.

The lack of this feature (actually N-way compare like aftershot has) is what prevents my from jumping ship to darktable.

In ASP, when in lightroom mode, you can select N shots and then immediately switch to "compare mode". Morever, when in darktable mode, you still get a film strip at the bottoom or the side, and you can select multiple photos there and then you automatically enter "compare" mode. In this mode, you get synchronized zoom by default. Then when you double click anywhere in one of the images, you get into synchronized "100% zoom" mode which is invaluable when you are looking for the image with the best focus.

Hoping to see something like this in darktable at some point.

A "compare mode" will be much appreciated.

+1 - this is an extremely useful feature in ASP and I would really like to see it available in darktable as well. Often times you take two or more shots of the same thing and want to be able to quickly compare them and find the best one. In ASP, when you select multiple shots for comparison, you can pan and zoom around one of them and it will pan and zoom correspondingly on the others, so you can both compare the overall image but also zoom in and compare specific parts as well.

The N-way compare implementation in AfterShot Pro is great. I'm badly missing that in darktable.

Side by side compare function was implemented earlier this month, by AlicVB, on development branch (that will be for major release for next christmas) on new expose and culling modes. That's a work in progress and some improvements would probably be released since Christmas on development branch.

Is it possible to test what has been implemented? Do I just need to clone/build https://github.com/darktable-org/darktable.git master?

#19 Updated by Nicolas Auffray 4 months ago

Yes, I use it since about 3 weeks. You of course just have compile and install the master from Github. Just don't forget that master is a work in progress so bugs remains.

#20 Updated by Nicolas Auffray 4 months ago

And if you test it, you could post issue you encounter. It's now better to post issues on github than here.

#21 Updated by Paul G. 4 months ago

Thanks, please excuse my stupid question, but how do I compare pictures. I installed the latest dev-snapshoot (iam on gentoo so I emerge darktable-9999, that should be git-master) and it shows me version: 2.7.0+1086~g7bbcd762e-dirty.
I am a bit lost currently because I am new to darktable..

#22 Updated by Andrew Martin 4 months ago

Note that there is a discussion about this new feature here as well:
https://discuss.pixls.us/t/help-with-culling-mode-in-darktable/12296

Paul, I made a post near the bottom of that thread detailing how I use "expose" mode to compare images.
