Apple is offering photographers, keen to see what the fuss is about, a free 30-day trial of its powerful Aperture software.

"Now you can enjoy a free 30-day trial of Aperture 1.5, the powerful all-in-one post-production tool for serious photographers. Try it, and you'll see how easy it is to import, manage, edit, catalog, organize, adjust, publish, export, and archive your RAW, JPEG, TIFF, and PSD images," Apple urges users.

The trial version is available in English, French, German and Japanese.

If you want to download and use the update, you need to fill in a form, and you will be sent a serial number that runs the product. Authorisation times out after 30-days, but purchasing the application gives you a new serial number which will reauthorise it once again.

The trial version doesn't include sample images or the tutorials that ship in the box.
