Avalanche for Lightroom 1.0.5

Ric Ford:

Avalanche is a native Mac app from CYME that promises to quickly migrate Aperture photo libraries to Adobe Lightroom or Lightroom catalogs to folders of files while using AI for some processing assistance…

Claudia Zimmer:

Avalanche was born out of our need to move massive amounts of photos from Aperture to Adobe Lightroom. We tried many different ways to achieve this and it was frustrating because it was often incredibly slow, and lots of edits were lost in the process.  Then we started to work on CYME’s ambitious photo project and realized that the first building block was a component that would understand the inner structure of all major photo cataloging apps (Aperture, Photos, Lightroom, Luminar, CaptureOne,…). Having this component to read from and write into any catalog format, would indeed allow us to convert between them. So we decided to release a first product that would be that converter and gradually add more input and output formats to it.

Claudia Zimmer:

One of the promises of Avalanche is to preserve the visual aspect of the migrated images by applying some clever algorithms to derive the adjustments in Lightroom (for example) from the adjustments in Aperture.


The idea behind ML is to learn from a set of images that have been adjusted in Aperture and Lightroom, what are the “functions” to apply to the set of parameters in Aperture, in order to find, one by one, the value of each parameter in Lightroom.

Other migration tools simply bake the adjustments and metadata into the image. Avalanche tries to migrate the master images and then set up equivalent non-destructive edits. Of course, this won’t always be possible, as the Aperture and Lightroom engines are not documented and don’t support all the same features.


But Avalanche goes one step further by attempting to migrate all the adjustments made to images into the destination catalog.


Avalanche does not require Aperture to run on the Mac. It can read the Aperture Catalog format natively.

Whereas Aperture Exporter needs to talk to Aperture via AppleScript.
