First, there doesn’t seem to be a way to automatically stack already existing RAW + JPEG images. In addition to the heavy toll the new features take on performance (although both Smart Tags and Facial Recognition can be turned off), there are still some areas that could be improved to help out serious photographers. Depending on your needs, you might want to turn the recognizer off most of the time, and experiment with it before leaving it on. Even a couple days later, Photoshop Elements 15 was still using most of my 6-core CPU to run the recognizer in the background on the images I’d imported. For comparison, Lightroom was able to make it through cataloging all those images in just over a day. After a few days (literally) it had gotten through about two-thirds of them. To test this, I pointed Photoshop Elements 15 at a 500,000 image folder hierarchy that resides on our high-performance Synology NAS (connected over Gigabit Ethernet) and let the app catalog it. Perhaps because of the additional overhead of the object recognition - although it and facial recognition continue in the background after images are imported - one place where Photoshop Elements 15 under-performs Lightroom is creating large catalogs. The software has a built-in, pre-trained AI sub-system that tags images with the names of common objects it finds in them as it imports them. One exciting new feature of Photoshop Elements 15 is common object recognition. Smart Tags: Pretty cool, but be prepared to pay a performance penalty

The new Motion Blur guided edit did a good job of faking motion, although a Radial Blur on the wheels would be needed to complete the illusion.
