Automatic Background Changer is a photo editing app that lets users create photo montages, thanks to the automatic photo background deletion (that is pretty accurate) and the ability to swap the background of an image for another.
To make a montage, all you have to do is choose a photo from your gallery or take a photo with the app's camera. Then, the app will automatically delete the background and you can set the blur level you want for this, as well as how close or far away you want it to be from the edges of the element to be cropped. Lastly, you can choose from the app's many predetermined backgrounds (a beach, mountain, forest...) or use a photo from your device and set it as the background. What's more, you can freely move and adjust the size of the cropped image to fit it appropriately.
Automatic Background Changer is an easy-to-use app with results that, although not the precisest in the world, and so don't create particularly credible montages, do let you have a good time creating unprofessional but fun montages.
