Here is how it works...

• Load a background image.
• Load a foreground image.
• Mask out unwanted portion of the foreground image using a wide range of masking tools.
• Smoothen the edges with smoothen tool inside the app, if required.
• Move, Scale, Resize, Rotate, Flip the foreground to place it on the right location on the background image.
• Adjust the colors/exposure/contrast/hue/saturation etc. of the foreground and the background images if required to match both the images in terms of colors.
• You are done! Save the blended image to the photo library at full resolution or share it on Facebook and Twitter.
