Wow. The article mentioned a camera in the $30,000-$40,000 range I didn't
know about, the Phase One medium format system. So they finally have true full-frame sensors in the Hasselblad size; and now this, 8 by 10 glass plate size. |

And Hasselblad itself makes the H6D-100c, so PhaseOne is not alone.

So they finally have true full-frame sensors in the Hasselblad size; and now this, 8 by 10 glass plate size. I don't really see the point, though. The main reason that large format film was popular was that you got higher resolution. There are plenty of ordinary digital cameras that exceed the resolution of this 8x10 format camera. In principle the huge pixels should allow for great dynamic range, but it doesn't seem like they're really getting much improvement there. So it really just comes down to the mechanics of it, and the ability to play some cute tricks with the alignment of the optics. Maybe there's a limited market for that, although I doubt there's much you can do with tilting the focal plane that you can't do already in Photoshop. |

Although its true that image manipulation programs can distort images in a keystone shape, and dropping the front is equivalent to cropping an image made with a wide-angle lens, what with the Scheimpflug rule, tilting the back controls which elements of an image are in focus, and that can't be done after-the-fact.

Depends on the subject, and the degree of perfection desired. That's actually not hard to do in Photoshop, although an imaging expert could probably tell the difference. For a static scene, however, like a landscape or architecture shot, you can do it by shooting a series at different focus positions and combining them. In fact, many cameras can shoot a burst sequence automatically that way, with 8-10 shots at different focuses in just a second or so. |

John Savard If any of those alternate array schemes was really demonstrably better than Bayer, it would have replaced it by now. Ultimately all filter systems will be abandoned. Why throw away photons? There are three sensor system that use tuned reflectors, so that every photon makes it to the appropriate sensor. But ultimately, I predict single sensor devices that record the position and energy of each photon that strikes them. I know there are experimental devices that do this, although making them practical is still a ways off. |

Well, we already do have Foveon, although I wasn't impressed by examples of pictures taken with it.
