Google announced the stand alone Photo's app at Google I/O a few weeks back. They made pretty big waves when they also announced that everyone gets unlimited 16mp photo and 1080p video storage for life! The old photos which is currently included in Google+ did include some editing features which really added some value. Once you accept the Google+ update to v5.8 you will find a warning which states that the Google+ version of Photos will stop working soon, and then links you to the standalone app. Once you update to the new Standalone app which is pretty well stripped down you can gain some of the old functionality with Sanpseed.
Head to the playstore for the new standalone app.
