The ability to show off your photos -- to clients or just to get an overall sense of a project -- has been vastly improved in Aperture 3. One area this is most apparent is the slideshow creation tool. Before this new version, to create impressive slideshows you would have had to use iPhoto, since that program had better tools for the purpose. 

In Aperture 3, you can either choose a theme on which to base your slideshow, or have complete control over how your project looks. You can choose how long to display a particular photo, add titles wherever you want and even include video and audio.

This tutorial is designed to show you how to make the most of this improved feature. If you don’t yet own Aperture 3, download a trial copy by visiting

1. A new slideshow  Start by selecting the pictures you’d like to work with. You could choose them from a single project or alternatively you can click on the sidebar’s Photos section to gain access to all your shots throughout the library. Once you’ve highlighted enough stills, go to File > New > Slideshow.

2. Theme selection  A drop-down sheet will appear offering you a choice of theme to use. Classic and Ken Burns are best if you wish to have as much control over your slideshow as possible. The other six themes come with fancy effects, but you can’t do much to modify them. Select Classic and click Choose Theme.

3. Altering slideshow settings  On the right are the slideshow’s main controls. Make sure the Default Settings tab is selected. Any parameters chosen here will affect all your photos, so it’s a fast, efficient way to make modifications to all of them in one go. Choose a format for your slideshow in the Aspect Ratio pop-up menu.

4. Filling the frame  The background colour is necessary if you want to see the full photo because borders will sometimes have to be added top and bottom or left and right. That border will take on the colour chosen in the Background parameter. If you don’t want a border, choose Fill Frame from the Crop pop-up menu.
