Finder: zoom into photo previews in Columns view

In the Finder’s Columns view, you can Option-click a photo in the Preview column on the right to zoom into it. You can then use two-finder gestures to pan around, Option-click to zoom in further, and Option-Shift-click to zoom back out.

This works on Mac OS X 10.6 Snow Leopard. Anyone have word on previous versions?
