Google Photos' Color Pop now available to some users
For Color Pop to work, the subject needs to be easily identified by Google's servers. If a picture does meet the requirements, a notification will appear in the Assistant tab of the Google Photos app, v.3.20. A Reddit user shared an image he took that was edited by Color Pop. That photo accompanies this story, and was snapped using a Pixel 2 running the Android P beta.
Keep in mind that for the moment, Color Pop is not an edit that the user can manually choose for any photo. That might change down the road as the technology improves. Right now, it is merely a suggested edit.
