Gus Mueller, writing at the Flying Meat blog:

In case you’re not aware, Retrobatch[1] is a node-based batch image processor, which means you can mix, match, and combine different operations together to make the perfect workflow. It’s kind of neat. And version 2 is even neater. [...]

Retrobatch is obviously not Flying Meat’s most important app (Acorn[2] would fill that role), but I really do like working on it and there’s a bunch more ideas that I want to implement. I feel like Retrobatch is an app that the Mac needs, and it makes me incredibly happy to read all the nice letters I get
from folks when they figure out how to use it in their daily work.

Five years after Retrobatch 1 shipped, I’m happy to see version 2 out in the world. And I can’t wait to see what folks are going to do with it.

“Node-based batch image processor” means that you design and tweak your own image processing workflows not with code, but through a visual drag-and-drop interface. (But you can use code, via nodes for JavaScript, AppleScript, and shell scripts.) You can program your own highly customized image processing workflows without knowing anything about writing code. It’s useful for creating
workflows that work on just one image at a time, but Retrobatch really shines for batch processing.

There are a zillion new features in version 2[3], but the star of the show has to be the new “ML Super Resolution” 4× upscaler: a powerful machine learning
model made easily accessible.
