Having shot extensively with oue 645Z over the last few months, I’ve developed a new hypothesis: the format – i.e. the physical size of the recording medium – matters to the output, but not in the way that we’d expect. Naturally, we assume that the larger the sensor or film, the higher the image quality. Since so much of that is both subjective and perceptual and thus affects the final impact of the image, perhaps it’s important to understand exactly what’s going on.
