External editor

Image-editing software can’t always do everything you need to an image, so most have the ability to use ‘external editors’ – they send the file to another program, where you make the changes you want to make, and then the edited version is sent back to your original software for any further work. This is how plug-ins work too, but the difference is that external editors are full-blown standalone programs. Only a few programs, such as Lightroom and Capture One Pro, support external editors.
