I have a picture of an object and I want to make the background of the picture white but keep the existing color of the object. The object has many rounded edges and is not easy to confine. Can I do this?
You can use the Wand tool to select areas of the image that are a common color. Once you select the area of the image that you want to create a new layer for, go to Float in the Layers menu. This will pop up a toolbar with a button on it to create a new layer.
