Remove noncontiguous backgrounds.
Learn how to use the Magic Wand tool to make automatic selections of nonadjacent background areas of similar colour. Uncheck Contiguous and play with the Tolerance field to adjust the level of colour variation that you want to allow within your selection.
Separate subject from background, even where they blend.
Capture fine details like hair or fur by opening the Select and Mask workspace. Use the Lasso or Quick Selection tools to capture a basic outline of the subject and then use the Refine Edge brush to refine your selection. With Edge Detection and Global Refinements sliders, you can fine-tune your selection even more.
Achieve a consistent look.
If the lighting of your new background doesn’t quite fit that of your subject, you can create consistency by duplicating the New Background layer and using the Blur filter to bring them together for a more natural look.
Discover fantastic worlds behind the background.
Go beyond replacing your image backgrounds by combining several images or specific elements from those images, to create scenes from your dreams.
Remove and add objects to your images.
If you want to remove just one element of the background image, you can use the Patch tool to sample a replacement element from another part of the background. You can also use the Crop tool to extend the canvas, fill that void and add more to your composition.
