Aligning Zoomed Images in Aperture 3
Joseph Linaschke has an old tip that’s new to me:
If you hover the mouse over any part of one of the images when you tap the Z key, Aperture will zoom into that point—but only for that image. If you are careful to have the mouse not pointing at any part of any image when you tap the Z key, then all images will zoom to the center. Great.

If you shift-click-drag on the white square inside the navigator, alignment will stay as-is. If you shift-click-drag outside the white square, then all images will align to the spot you clicked on. Perfect!
