Should I short digital camera manufacturers?
In article dhosting.com, Mathis Lefebvre wrote: With every single person holding a cellphone camera in their pocket, I can't see how they can survive. The market for compact point & shoots is shrinking, but anyone who was using a DSLR or MILC or even a bridge camera won't settle for a camera phone. Whether young people will continue to go *into* serious photography as a hobby is a good question, though. -- Money is Speech Corporations are People Freedom is Slavery Ignorance is Strength |

Whether young people will continue to go *into* serious photography as a hobby is a good question, though. of course they will, but it won't be the same as what the old farts think of as photography. the future will be largely software and image processing. |

I don't think cell phones are going to get enough thicker to change the angle but for consumer applications they seem "good enough" except that the sRGB color standard doesn't cover all monitors/TVs and some cameras export less quality color reproduction than is what is on the phone display, some phones don't even keep the rotation right -- Dale |

The work is being targetted at thin flat cameras suitable for cellphone use. I am aware of no indication of how good this may turn out to be. -- Regards, Eric Stevens |

At least one person has claimed to have taken apart a Lytro and found it to be very different from what was claimed--a simple camera in perpetual hyperfocal mode. The "focus after the fact" effect, they claimed, was acheived by selectively blurring things in software. -- Money is Speech Corporations are People Ignorance is Strength |

No better than the sensor size of a cell phone camera allows it to be. IIRC that particular concept is trying to use interferometric techniques to synthesize an image from multiple sensors. If it works then it could give remarkably high resolution, but won't do much for sensitivity. More coded aperture convolutional coding than interferometry. You can't sensibly do interferometry without using close to monochromatic light. It is more like a very sophisticated version of a pinhole camera but letting a lot more light through to the focal plane.
