Greg Newman has cheat sheets for Aperture and Lightroom on his site. His screen shots take you to Flickr, so don't go there.

What you really need is to look for the links under the images and download the ZIP files, two for Lightroom (Mac and Windows) and one for Aperture. After unzipping you'll find a large PNG image for on-screen use and a PDF for printing.

Apple recently released an export SDK for Aperture 1.5.

What is that? It's a set of files used by programmers who want to add functionality to Aperture's exporting capabilities. Programmers use the SDK with other Apple tools to create plug ins. Once installed, they show up in the File > Export menu. The idea is that anyone who wants to export from Aperture to another application or web service can now write the necessary code to do so.

The code is currently pre-release, so it is only available to Apple developers (who are subject to non-disclosure agreements). Go to the developer site and log in to download it. However the reference documentation and the SDK overview are freely available.

Rather than bring you fish, I will tell you how to catch them yourself. Go to Apple's search page and type kf8 into the search box. All the Aperture Knowledge Base articles are tagged with "kf8". On the results page, sort by date to see the latest. Or you can just bookmark this URL to do the search in one click.

You can download all the movies in one go:

1. Open the Download window in Safari
2. Highlight the text below
3. Drag and drop it onto the Download window
4. Have a large cup of coffee. The movies are pretty big.
