: Maybe it's time for a sensor produced with random pixel sizes and organizations? Be interesting. That would make images a bit more aesthetically pleasing than using an unfiltered uniform sensor with the same average pixel size, but it will still be error-prone at low densities. It would simply avoid simple repeating aliasing patterns; there would still be false detail. A system where a white pixel can exist next to a black one (in the same color channel, of course) can never give accurate imaging. |

wrote: Some people *like* aliasing, because they are optically naive and don't recognize real detail vs aliased apparent detail. that's sigma's secret sauce. the aliasing doesn't have false colour so they can get away with it (and even claim an anti-alias filter isn't needed). a lot of people fall for it. Me, personally, I get a very disturbing feeling when looking at aliased images. Even downsampled, sharp images from the Sigma SD9 give me the heeby-jeebies. They look like a small nearest-neighbor downsample of a much larger image; with entire columns and rows of pixels removed, and the remainder expanding to fill in the gaps. not only are the images aliased like crazy but they're *also* oversharpened. it really hurts. |

We're all still waiting for just one image from any camera you've ever touched in life. But we all know better, don't we. You're a pretend-photographer troll who's never touched any real camera in your lifetime. |
