The Software Manager says I have it pre-installed, and Terminal tells me it is up-to-date.
How do I open it in order to use it?
Sorry, basic. But I cannot find.

Re: How to open Imagemagick?
It doesn't run under the name imagemagick, rather it uses differently named commands that relate to the function of said command.
The only one I use is mogrify but there are many others. What makes it so great is you can do a batch run from the command line or a script and it is a lot quicker than doing the same thing in a GUI program.
For example:
What that basically does is convert huge jpg files to a smaller size. You would cd to the directory with the pictures and just run it.
You could put a whole bunch of these commands into a script and just run the script and walk away.
It's been a while since I used a GUI program but I remember you couldn't do it that quickly back then, I don't know if you can now or not.

ImageMagick is a set of tools that are run from the command line. There is a GUI for it, but it is also started from the command line. Open a terminal, enter
For more information about IM and its tools, go to https://imagemagick.org/index.php. I think IM is worth the effort to learn to use, but there is a learning curve.
Here are some ways IM can be used.

I use the IM convert tool for several tasks. This example reduces the size of the JPGs in a directory by 50% and append "_small" to the filename. This uses the convert tool, along with the shell utilities "find" and "xargs". The “-l” makes it process one line at a time. The “-i” makes the “{}” to stand for file name.
I use the IM montage tool to create contact prints. The command I use creates a contact print that has up to 24 thumbnails per page, each thumbnail is 250x250 in size with the filename as a label, and it will generate a multi-page PDF for contact prints of 25+ images.
You can create a quick/dirty contact print of every .jpg in a directory with
