Here goes another tomato
That's a really cool project; thanks for the link!
6-micron resolution is pretty awesome, when you get right down to it. There are plenty of applications where that level of precision is a godsend.
But that resolution would allow you to blow up a photograph of an orchid in a patch of rivergrass to the point where you could see the plant's individual cells. This is like buying a Hasselblad to shoot pix at a company softball game. It's not that it's actually bad; it's just overkill.
There will always be a place for every sort of technology in art. Heck, there are still folks out there creating images using a polished silver-plated copper plate, sensitised with vaporised iodine and developed with the fumes of mercury because it gives them an effect that they want.
Sorry to tell you this but they do use film, 91/2" roll film I think.
