Inspired by a conversation on Micro.blog with @jack, here’s the Retrobatch document I use when manually setting the date metadata from the filename, and adding a watermark:

(The details in the sidebar are out-of-order; look at the nodes in the circles for the order they are executed.)

I use a similar document when doing it automatically, with the input coming from a Folder Action in the Finder. I can just capture a still from a camera watching the feral cats, chickens, etc, and it is saved in a folder that has a Folder Action script to open in Retrobatch, the metadata date is set from the filename, the watermark added, and saved to another folder, that then has another Folder Action workflow to import into Photos.

Here’s the Folder Action script to open the images in Retrobatch, then trash the originals:

This is the Retrobatch document (again, the sidebar is out-of-order). It takes the input files from the folder (via the above script), sets the copyright notice in the IPTC metadata, sets the date metadata from the filename, adds the watermark text, and saves as a more efficient HEIC format (since the input is inefficient BMP images):

The processed images are saved to a new folder, which has it’s own Folder Action. Here’s the Folder Actions window in the Finder:

The output Folder Action runs this workflow to import the images to Photos. It is supposed to also trash them, though that doesn’t work:

Before Retrobatch, all that was a tedious process of looking at each image and manually adjusting the date by reading the datestamp in the image, and manually importing. Now, I just click one button, and all the rest happens like magic. A huge time-saver!
