ABSTRACT
Photoshop supports nearly all the current, well-known image file formats. And for those that are not supported, you will find that certain specialized file format plug-ins are supplied as free extras for Photoshop. When these plug-ins are installed in the Plug-ins folder they allow you to extend the range of file formats that can be chosen when saving. Your choice of file format when saving images should be mainly determined by what you want to do with a particular file and how important it is to preserve all the features (such as layers and channels) that may have been added while editing the image in Photoshop. Some formats such as PSD and PSB are mainly intended for archiving master image files, while others, such as TIFF, are ideally suited for many types of uses and, in particular, prepress work. Here is a brief summary of the main file formats in common use today.
