You can extract an image from an image using Preview and paste it somewhere else. See: https://support.apple.com/kb/PH20228?locale=en_US&viewlocale=en_US. It's not as precise as a "real" post-processing program, but it simple, it's part of MacOS, and it works fine for well-defined objects.

Well, Kary Mullis did win a Nobel prize for his work, and his consulting and lecturing fees were/are probably quite handsome. His original technique was rather cumbersome (though brilliant), and I think it was after Mullis left Cetus, that Cetus scientists developed a machine that streamlined the process, making it much more efficient, useful, and doable for the general scientific community. At that point, Cetus got rich from licensing the process :) I always had the impression that Mullis had the idea, but others did the heavy lifting to prove it and make it available. Having an idea is one thing, but having the talent and resources to develop it is a different level. This is getting a little tangential, but had he been at a university, rather than a pharmaceutical company, he probably would have profited more as most universities split licensing profits with the inventor.

This is Whiskey.

It looks like blue plumbago - beautiful shot!
