It's time to end the megapixel race

Discussion in 'Digital Cameras' started by Charles Schuler, Oct 12, 2006.

  1. Cramming more and more pixels onto small sensors is a marketing ploy, with
    disadvantages to unwary consumers:

    1/ Less dynamic range ... more noise (especially above ISO 100)
    2/ More aliasing (Moiré effects)
    3/ Color fringing

    There are others, and I'd appreciate your input.

    The Federal Trade Commission once weighed in on the "watts per channel"
    issue. (http://www.ftc.gov/os/1998/07/63FR37237.pdf)
    I hope that megapixels will soon be addressed by the FTC. I am not thrilled
    with government intervention but, with modern technology, there seems to be
    no other choice.

    I teach "digital photography" in my community and am overwhelmed by the
    megapixel issue. Too many have latched on to megapixels as THE defining
    quality. Manufacturers respond accordingly.

    It's time to throw some reality into this mindless craze.

    There's a difference between the megapixel race, and the FTC's
    complaint about amplifier ratings.
    The power ratings were deceptive, while the stated number of
    megapixels isn't (with a very few notable exceptions).
    But, IMO, those who reach for the most megapixels aren't the sort who
    really care about the technical quality of the images, anyway. They
    aren't being cheated, because they get what they are promised: so many
    megapixels.

  5. Yet, this seems to me a lesser evil than computers being sold on clock
    speed primarily.

    No you will have less not more Moir'e effect, higher sample means less
    aliasing.
    Less of this as well.

    While what you say is logical, it is not always evident in practice. Look at
    the Canon A630, 640 Moiré Monsters Canon created. Perfect example is the
    sample pictures of the brick fire station building on Stevesdigicams. Was
    considering upgrading my A610, but the new versions have moiré issues.

    FTC won't be involved because the cameras DO have the number of pixels
    quoted. Remember when Fuji used to interpolate to double the MP count? Now
    that was rediculous! I do agree the MP race on smaller cameras is BS. At
    least from the few samples I've seen, it is evident that the 10 MP are
    pushing the limits too hard.

    DSLRs are another matter. I think at 12mp, the 1.5/1.6x APS sized sensors
    are at their limit because the resolution is now of that of high end glass.
    Full frame sensors probably could go into the low 20MP range. Medium format
    based digital, with sensors of 40MP in production now probbly don't need
    much more either.

  9. Remember that Bayer pattern sensor have only half the (linear) resolution
    for (pure) red and blue.

    Pushing the sensor resolution beyond what lenses can deliver reduces aliasing
    effects and/or can be used to reduce the strength of anti-alias filters.

    Of course, if you push too far, some people will lose the low noise performance
    they need, other people will lose the dynamic range they need. And at some
    point there are not enough oppotunities to really benefit from the increased
    resolution (i.e. you have to use a tripod, or there has to be enough light
    for fast shutter speeds).

  10. I had a similar take when I saw a new restaurant claiming it offered
    "gourmet burritos". An oxymoron in my book, but mileage varies.....

    It occupies a hallowed space in my oxymoron organizer. :)

  12. It's kinda hard to put a digital picture in your wallet. To carry a
    digital picture, you need something along the lines of a PDA or one of
    the new pocket sized digital picture frames. Or keep them in your
    camera and carry the camera everywhere you go.

  13. It is alleged that Scott W claimed:
    I didn't read the rant as being merely about the number of pixels, but
    rather the number of pixels in a given amount of space.

  14. Wallet sized photos can be displayed pretty well on most mobile phones -
    ideal for keeping a picture of your pet or your loved one!

    I agree, at this rate the whole world will be nothing but pixels. We
    should have the government tax them, that will take care of the problem.

    Clock speed doesn't seem to be an issue since Intel finally admitted AMD
    was right for all of those years by not playing that game.

  18. I have a Canon G3. What "older technology" disadvantages it?

  19. The iPod video and even the Nano do well at this. Oh, they also play
    music. And keep calendars and address books. And can store photos off a
    CF card with a purchased gizmo, although I haven't done that last one.
