The program is based around the concept of layers. These allow you to easily edit images, and composite or blend multiple images together. The program is also capable of reading and writing a huge variety of file formats (including both raster and vector formats), and works with a variety of color models including RGB, , grayscale, CMYK and duotone. As you might expect, Photoshop interoperates very well with other software by Adobe Systems Incorporated.
Adobe Photoshop is an extremely well thought-out program, with a clean user interface. However, beneath that user interface there is a lot of complexity - both because of the range of features available, and because many Photoshop novices do not have extensive previous experience in the world and terminology of graphic design. It is for this reason, that beginners to Photoshop can often greatly benefit from training and tutorials. A variety of Photoshop tutorial web sites, software training packages and, of course, Photoshop books, are available. These types of resources really can help you master Photoshop incredibly quickly!
