[Android™ 4.4, KitKat] How do I take an Eraser photo using my Samsung Galaxy S® 4?
The Eraser photo option lets you capture five photos of a scene and erase unwanted moving objects from the background.
To turn the eraser photo feature on, with the camera application open, touch Mode and then touch the Eraser thumbnail.
Aim your device at the scene and touch the screen to focus on a specific area. When the focal point turns green, touch the camera shutter button. Five photos will be captured in quick succession and your device will detect any moving objects. If a moving object, which can be removed, is detected, it will be highlighted in pink. Touch the area to remove the object from the image.When you are satisfied with the changes, touch Save.
