Google Photos brings most of the features that were already available in Google+ Photos (which will continue to exist). There are some improvements: for example, Google now maintains the original resolution up to 16MP for photos, and 1080p high-definition for videos if you want to store your photos and videos for free. Another improvement is that Google Photos does a better job at organizing and grouping photos by people, places, things, types.
"The app can also help you quickly enhance photos and combine them in new ways to help you relive your life's moments. In one tap, get instant adjustments tuned to the photo's color, lighting, and subject to make each photo look its best. Press the + button to create your own collages, animations, movies with soundtracks, and more," informs Google.
Auto Awesome is now called Assistant and it suggests new animations, collages and stories created using your photos and videos. You can dismiss them, edit them or share them with your friends.
Sharing works much better, even if you're not using Google+. You can select some photos and quickly get a link you can share with other people. "The recipient can see what you shared without a special app or login, then immediately save the high-quality images to their own library with a single tap."
