I'm using Darktable to edit photos. There is one option, which I'm still looking for, but it seems to be unavailable or hidden somewhere. How to (after making some changes) preview a source image in order to compare before & after versions?

It's possible to turn on and turn off one separate function (small power off button next to an option), but how to switch between before/after without clicking each of them separately?

Have a look at snapshots, top left in the darkroom mode. For details, have a look at

Does it mean that I should make a snapshot every time at the very beginning (before all the changes are made)? –  kurp Jun 22 '13 at 18:05
Not necessarily. At any time, you can go back in the history stack and take a snapshot of the older version. But be careful to go back to the top of the history stack again. Otherwise, if you cange something, it is applied to this older version, and you lose all later changes. –  bronger Jun 23 '13 at 14:41
