Interpolated pixels e.g. 2MP Effective 4MP Interpolated???

    Is this just a gimmick?

    If you understand what the interpolated pixel feature does can you explain
    it? maybe with reference to the following questions.

    Is there any real use for this feature on a digital camera? Will it improve
    prints? If so can software on a computer do just as good a job?

    Found myself this page which explained a lot.

    So yes I guess but very limited.
    If printing large enough
    Yes and better, more appropriate for use.

    Feels like bad form to reply to my own post, feel free to join in.

    YES---marketing hype. Fuji is the current worst offender
    Up-sampling (interpolation)--in the camera or the computer---is uesful
    to removed the jaggies and maybe to smooth out some noise and other
    artifacts. It can never add to the inherent resoltuion of the
    image---even if you are using Fuji super CCD diagonal pixels.

    More control if you just take basic pix at full camera resolution and
    then do the processing in the computer.

    Everybody talks to themselves sometimes :)

    You may want to check out Genuine Frcatals from http://www.lizardtech.com/solutions/gf/ - it
    can produce larger printable versions of your images without tremendous loss of quality - of
    course you will need Photoshop or Photoshop Elements to use the plug in and get the
    bennifits - they also have a starter edition which appears good value ... Zol.

  5. In the case of the Fuji cameras, the higher output resolution is
    necessary to *retain* the resolution captured by the camera. A 3 MP
    Fuji camera writing a 3 MP output image provides less total information
    than other 3 MP cameras. A 3 MP Fuji camera writing a 6 MP image
    provides the same total information as other 3 MP cameras, and more
    horizontal/vertical resolution.

    Whether the increase in horizontal/vertical resolution is useful is a
    subject for debate, but the interpolation used in the camera is
    *necessary* to retain that information while rotating the sampling grid.
    It is not empty magnification like "digital zoom" on other cameras.

    Some newsgroup contributors appear to have confused
    the meaning of "discussion" with "digression".
