I would suggest you actually learn how to use an ULF camera before you claim they have no relevance and that digital does it better. Photography is not about test charts, in the end, I would put any of my prints against any of yours (enlarged or contact) any day of the week and twice on Sunday.I would suggest shooting some test targets, so we have something objective too look at.....it will provide a better illustration of your assertions.
I have posted images, you have nothing but theory and conjecture. I think people can arrive at their own conclusion as far as the subject of ULF having any utility.
Don't waste your time, you could not use one on a tripod...I plan to carry a handheld 16x20 for those candid moments.
