Creating shapes in Photoshop

The Shape tools allow you to create vector-based elements in your image. Depending on the mode selected, these elements are automatically filled with the foreground color or left as just an empty path. The beauty of vector-based elements is that they are resolution independent, meaning that they always print at the resolution of the output device rather than the resolution of the image. Vector-based shapes created with the Shape tools can also be resized and transformed without any quality degradation, unlike raster images. Although vector-based elements are the heart and soul of the Shape tools, you can also create shapes filled with pixels of the foreground color.
