File format

Images can be saved in a variety of file formats. Different file formats exist because some are better at certain tasks than others. Some file formats are associated with specific software programs. For example, Adobe Photoshop's file format is .PSD.

However, graphics packages also allow the user to save their work in compatible file formats that can be used in a variety of software programs - eg .JPG, .GIF, .TIFF. Most digital cameras automatically save photographs as .JPG and these can be used in a variety of graphics packages.
