Thanks PE. That's what I thought. Sharpness problems would probably be lessened for projection (or even scanning) if the three positives were bigger than 35mm, or even medium format. Of course if you're gonna scan it, all you really need is the separation negatives and put it back together in post - which of course makes it a hybrid process. At least for me the reason to shoot chromes is for projection (secondarily to have a good color reference in-hand to give the printer for prints).

<tongue-in-cheek>Who's gonna start making this new Apugchrome film and a camera to shoot it in? </tongue-in-cheek>
