The AI-powered Select Subject feature that Adobe demoed back in November has finally arrived in Photoshop CC! The feature was officially released just minutes ago in Photoshop CC version 19.1, which also includes the addition of a Decontamination slider to the Select and Mask workspace and some significant compatibility updates for Windows users.

The major update is, obviously, the arrival of Select Subject to Photoshop CC. When it was first demoed in November, the Photoshop team touted the tool—which is powered by Adobe Sensei AI technology—as a way to "select prominent subjects in an image with one click." That's what they hope to deliver today.

A single click of the Select Subject button in the Quick Select tool should easily isolate your subject in images like the one below:

Of course, more difficult scenarios where the subject isn't so obviously delineated against the background will give Select Subject more trouble—the original demo video, embedded below, showed that—but it promises to "let you get started with your selections faster than ever before."

In addition to Select Subject, Adobe also added a Decontamination slider to the Select and Mask workspace that allows you to select the amount of color decontamination applied to an image:

For Windows users, version 19.1 brings much-requested support for Windows High Density Monitors—allowing you to switch between displays of varying resolutions and sizes seamlessly. Jerry Harris, principal scientist on the Photoshop team and himself a Windows user, explains what this means in the Adobe blog post:

With this release, Photoshop on Windows 10 Creator’s Edition now offers a full range of choices for UI scale factors from 100% through 400%, in 25% increments. This means that the Photoshop user interface will look crisp, beautiful, and the right size no matter the density of your monitor. Photoshop will now automatically adjust itself based on your Windows settings, making it simple to set up.


In addition, we worked very closely with Microsoft to provide per-monitor scaling across monitors with different scale factors. This means that a high resolution (HiDPI) laptop now works seamlessly alongside a lower resolution desktop monitor (or vice versa). One monitor can have a scale factor of 175% and another a scale factor of 400%.

And finally, Windows users also get advanced support for the Windows dial, which can now adjust brush settings while you paint. Before this, you could only adjust settings between brush strokes, but you can now adjust brush size, opacity, and other settings as you draw:
