With the new Paper, we completely rethought photo filters. Quickly point to a specific area in photos and screenshots that you want to show with just a tap of your finger.
To start, press the "+" button to open a new canvas. Tap the camera icon to take a photo or select one from your Camera Roll. Tap the Spotlight button to add an overlay. Draw or tap to spotlight details anywhere on the photo. (You can spotlight more than one detail per photo.)
Changed your mind? Edit or remove a spotlight from a photo by tapping the camera icon and then the "x" above the word Spotlight. Press done to exit.
