Create Large Document Format (PSB) Format in Photoshop

Work with humongous files? Then you’ll be pleased to know that the Large Document Format supports files of any size. Besides the Photoshop Raw and TIFF file formats, the Large Document Format is the only other format that can save files over 2GB. What’s even better is that the coveted features, such as layers, layer effects, and filters, are all supported by this format. If you want to work with large files, just make sure you have the Enable Large Document Format option selected in the File Saving panel of your Preferences.

You knew it was too good to be true, right? Just remember that Large Document Format files can be opened in Photoshop CS only. So make sure any recipients of your files have the latest and greatest version of Photoshop. This limitation isn’t confined to older versions of Photoshop either. Be forewarned that many other applications fall to their knees when presented with a file size larger than 2GB.
