3D Overlay Photo Blender App is an amazing photo editing app that lets you make your pictures look like they are part of a 3D scene. All you need to do is take a picture and then add one or more objects to it to give it a more realistic look. You can choose from a variety of different objects such as trees, rocks, or other objects that you have in your surroundings. Once you have one or more objects in the picture, you can move them around to place them in different locations in the 3D scene.
The app has a very easy-to-use interface, so you don’t have to worry about how to use it. The first thing you will need to do is select a photo from your device’s photo gallery. You can select a photo from the camera or the gallery. You will be able to see the photo that you have selected in the preview window.
