Graphic design is the most widely used field of Photoshop. Whether it is a book cover, a poster or a poster, these graphic prints usually need Photoshop software to process the images. Advertising photography is a kind of work with very strict visual requirements, and its final product often needs to be modified by Photoshop to get satisfactory results.

Interface design is a new field, which is paid more and more attention by software enterprises and developers. There is no professional interface design software at present, so most designers use this software.

You can use the shape tool or the pen tool to create a shape layer. Shape layers can be easily moved, aligned, distributed and resized, so shape layers are very suitable for creating graphics for web pages. You can choose to draw multiple shapes on one layer. The shape layer contains a fill layer that defines the shape color and a link vector mask that defines the shape outline.

A shape outline is a path that appears in the Paths panel. Drawing directly on a layer is very similar to the function of a drawing tool. When you work in this mode, you create a raster image instead of a vector graphic. The drawn shape can be treated like any raster image. In this mode, only the shape tools can be used.
