The ability to ‘stack’ related images is, I think, one of the single most important features of image cataloguing applications. And Aperture’s stacking system is the simplest, most effective and most versatile of all.

To show how it works, I’ve set up a project with just a single image. It’s going to be a lot easier to see what’s happening if the screen isn’t cluttered up with other pictures. There are lots  of screenshots with this walkthrough, but don’t worry about that because it’s not a complicated process – they’re there just to make every single step crystal clear. And don’t forget you can click on any of these screenshots to see a larger version if the details are hard to make out.

01 Create a new version of your photo

Aperture stacking secrets

To show stacking in action, I’m going to start from my original image and open it in another editor from within Aperture. (You could also create a new version within Aperture and adjust it with Aperture’s own editing tools.)

02 The stacked versions

When you’ve finished editing and the image is saved, you’re returned back to Aperture and the new image is stacked with the original – this is shown by the larger grey box around the two ‘stacked’ images.
