Calculation Tool

My absolute favorite tool of Photoshop has to be the calculation tool. It leaves specific parts of an image in its initial shape without any jagged cutouts or any background image remaining. I took this black bear from this website and added it to this background found here to create this image. The tool has its limitations since it can't distinguish similar colors of a background and foreground, but a little tinkering around can fix that. The image is converted into a black background and white foreground. The dodge and burn tool are perfect for whitening highlights (foreground) and darkening shadows (background).
