Just choose a command and let it run

“

- The subject of this chapter is quite literally subject. It's a command. It lives in the select menu and its name is subject. So select subject. In other words by choosing this command you're telling PhotoShop to select the subject of a photograph. Most notably, a person, an animal, a car, a toy, that's all according to the documentation by the way. Or some other prominent image element. All you do is choose the command and let 'er rip. There is no dialog box. There are no controls. The selection just happens. From that 'vantage point, the subject command either works and its magic. As in the case of this notorious character or it doesn't. I mean it did okay. But it cut off Venus's head. I bet illustrator wouldn't do that. Adobe is not divulging exactly how select subject works. Except to say that the command is and I quote, powered by advanced machine learning technology. So perhaps Adobe has trained the select subject command to select a few thousand famous image types like the low-hanging fruit that is the Mona Lisa. But your photographs. The ones that you or your co-workers shoot. They're going to include subjects that Adobe has never seen before. So here's my theory. Select subject does not so much expand the selection around the subject of an image as collapse it inward beyond all the non-subjects. By which I mean, PhotoShop reads the four walls of the canvas and retracts the selection inward to include what it perceives to be the high contrast objects. Which means, I mean clearly, no way its gonna be able to select anything in this image, right. Everything is high contrast and so whoa! I mean, never mind. Select subject might actually be magic. Which I hope can also be said of the next movies.
