I do understand about print media requiring an image to be XxXxDPI (8.5x10x300) but, as you said, that equates to 2550x3000. Since Carrara DOESN'T allow you to specify inches (or cm, or picas for that matter,) just dotsxdots, then DPI is irrelevant. Or am I missing something? One of HD-TV's spec's is 1280x740, but 35mm film is, theoretically, up to 4000x4000! I depends on film stock, processing accuracy, the phase of the moon, was it made on a Friday, or Monday. ;>
