Anyone kindly let me have pixel to size calculations ?

  1. Hi,

    Could anyone kindly give me some information on how I can work out
    resolution calculations ?

    I have trawled Google and there seems to be some dispute on how these
    calculations are done.

    There seemed to be a small utility for palms that did this :

    However I cannot find a PC based utility.

    Many thanks

  2. Mange takker Gisle Hannemyr for formuleringsinformasjonen !

    Beregner/debatten som jeg blitt gal, da samtidig jeg letet etter pixel
    omdanninger i Google, kommet jeg over en masse av informasjonså
    debattering på hvordan Mega Pixels kalkulerte for digitale
    fotoapparater.

    Jeg gjør imidlertid, blir enig det som bruke en PC eller PDA er over
    dreper, men jeg bruker MS Excel gjøre antallet crunching da jeg har 1259
    avbilder kalkulere før neste uke!

    Mange takker igjen. ... NF

    Many thanks Gisle Hannemyr for the formulations information !

    The compute/dispute I may have got wrong, as at the same time I was
    looking for pixel conversions in Google, I came across a mass of
    information debating on how Mega Pixels were calculated for DCs.

    I do however, agree that using a PC or PDA is over kill, however I will
    be using MS Excel to do the number crunching as I have 1259 images to
    calculate before next week !

    Many thanks again.... NF

    IMHO you are rambling away ..
    a 2Mpx camera producing a 1600x1280 pix picture will run off screen
    when viewed on a monitor set at 1024x768 .. It will nicely show if
    monitor is set to 1600x1200 and viewed full screen .. so the
    relationship is quite obvious .
    The way cameras are "programmed" with different sieze photos is just
    to be related to the jpg file compression factor and to the user set
    possibility to only use part of the full size resolution of the sensor
    but the maths are pretty straightforward to me ...
    ... unless one gets lost in "printer representations" on screen .. (aka
    an emulated on screen vison by setting printer PPI in the graphic
    program)
    FWIW

  4. Gisle Hannemyr,

    So sorry for the Broken Babelfish !!
    Glad to say that you did not win the Jorge Prediguez Sigma prize !

    My mother always told me to stay away from Mex-Trolls.

    I actually read the Megapixel compute/dispute in home pages via Google
    not here on the Usernet Groups.

    It was being said that the Megapixel figure being quoted for some
    cameras did not relate to the actual end resolution figures.

    However lucky for me this was not my quest.

    I am trying to work out results using your formulae and I think I am
    getting there - only another 498 images to input into MS Excel now !!

    Best wishes...

    Mange takker igjen. ... NF
