A few months ago, I heard someone mention the technique of aperture stacking, in which a series of images taken over a range of apertures is stacked together in software in order to improve depth-of-field in a composite photograph. In other words, an alternative to focus stacking for when your lens changes magnification as you shift the focus. Well, the aperture stacking thang didn't do nuttin' for me in this particular scenario. In fact, a single image seemed to work just fine, thankee very much. I'll keep looking.
