>Similarly, just because you can technically put the entire scene into focus all the time doesn't mean you necessarily want to! Sometimes you technically can't put the entire scene into focus. Even if you have unlimited lighting, there's only so far you can stop down the aperture before diffraction wipes out your depth-of-field improvement. Citizen Kane famously used composite shots to achieve extreme deep focus that would have been impossible as a single shot. I'd love to see another attempt at a photorealistic 100% CG movie like Final Fantasy: The Spirits Within. We'd be free from the limitations of real world optics, and could produce a "hyperrealistic" style even better than what you can see with the naked eye. I find shallow depth of field almost as annoying as low frame rate.
