How do I invert an image in photoshop express ver 3?
The previous implementation of the invert effect was not compatible with our new rendering engine, so it was not included the most recent release. We apologize that some items are not in the recent release that you had in previous ones. It is one of the effects we are considering for a future version. We would love to have your feedback in this survey so we know which effects and borders you are most interested in: https://www.surveymonkey.com/s/DYGG2RH
