Removing the background from a photo!
One of the best new features that came with Keynote '08 is the alpha option that lets you remove an unwanted background from a photo in a second. One of the things that you might have noticed is that you cannot easily copy this effect from Keynote to another app such as Microsoft Office. This wouldn't be a problem if the alpha feature was standard around iLife and iWork, but it is not. There is a workaround however and that is because you can copy and paste it from Keynote to the rest of the iWork suite. To bring the photo that you modified in Keynote into any application, copy it from Keynote, paste it in Pages. You can then copy it back from Pages and paste it into any application without losing the effect that Keynote gave you.
