ON1 Photo RAW’s Versions feature lets you create a ‘virtual’ copy of an image, which you can edit in a completely different manner than the original file, but without actually duplicating the image. This lets you easily try different preset treatments, crops, and retouching operations on a copy of the same image without having to lose any work—or see your disk space increase.
Creating a version is easy: in any of Browse’s view modes, choosing Create Version from the Settings menu (or choosing Command-’ or Control-’) will create a new version of the currently selected (or viewed) photo.
A copy of the image will be created next to the existing one in your library, with a ‘v1’ added to the filename. (Additional versions will be numbered sequentially.)
A version acts like most images inside Photo RAW. You can open it in any of the Edit module tabs; crop or make any adjustments with all of Photo RAW’s tools and filters; and you can edit its metadata independently of the original. You can even export a versioned photo or use it in Resize (Photo RAW creates a rendered file in those instances). You can not create a version of an .onphoto file that has layers in it, however. You must first flatten the image inside the Edit module.
In Grid view, versioned photos will have a small square badge split into light and dark triangles.
