The STiNG file support is provided in Perfect Resize 7.5 for opening exsiting .STN files for legacy users. STiNG is no longer a recommended format and this is the last release of Perfect Resize to support it. It is recommended that existing .STN files are converted to a modern format, like JPG2000, which maintains the wavelet compression but is more compatible and is an industry standard. STiNG files are not readable by Adobe® Lightroom® or Apple® Aperture® or natively in the Perfect Photo Suite. The only way to open STiNG files is via Adobe® Photoshop® if Perfect Resize 7.5 or earlier is installed.
