The history stack stores the entire editing history for a given image, in the order in which those edits were applied. It is saved to Ansel’s library database and the image’s XMP sidecar file and persists between editing sessions.

Each time a processing module is enabled, disabled, moved or amended a new entry is added to the top of the history stack.

The history stack can be queried and modified within the history stack module in the darkroom.


Note: The history stack is not a representation of the order in which the modules are executed but the order in which they were amended. The execution order is represented by the order of the modules in the right-hand panel.
