- Description
- This format is used to compress TIFF images when sending them via fax machines. This format helps reduce the data transmission time. Group 3 eliminates redundant data during compression in order to reduce file size. The standard 10:1 compression ratio may be increased to the user's preferences, but it can lead to a significant loss of image quality.
- Format used for saving large Photoshop documents over 30,000 by 30,000 pixels in size; supports images up to 300,000 by 300,000 pixels; to enable .psb support, check the "Enable Large Document Format" within the File Handling pane of the Photoshop Preferences window
