Retrobatch is a new batch photo processing app for the Mac from Flying Meat, the maker of Acorn. Batch processing of photos isn’t new. There are plenty of apps available that let you manipulate collections of photos. What’s different about Retrobatch is how it goes about processing images.
If you’ve ever used Audio Hijack from Rogue Amoeba, you’ll understand the power of Retrobatch immediately. The app is based on the idea of linking individual nodes together to create complex workflows. Point your new workflow at a batch of images, hit go, and Retrobatch goes about its work, delivering your processed photos to wherever you specify. The power is in abstracting complex actions into simple building blocks that can be strung together and branched as though you were building a flowchart.
That last point is the essential distinction between Retrobatch and other batch processors. Most image processors are linear, moving through a series of steps that outputs modified images. Retrobatch’s nodal structure allows you to start with a folder of images, perform actions on them, and then branch off to different actions at any point in the process.
