    Talking relationship between photo quality and pixel

    Hi all,

    I have few questions here:

    For a DC with 4 megapixel,

    Q1.
    what is the max. size of photo that it is able to print without any quality degradation?

    Q2.
    If I use this camera to take a photo with only 1900 x 1600 (i.e. the max. pixels of 3 megapixel DC), does the photo quality will be same as the one taken by 3 megapixel DC?

    For a DC with 3 megapixel,

    Q3
    what is the max. size of photo that it is able to print without any quality degradation?

    Thanks.

    For acceptable print quality, divide pixel width/height by 150(ppi).
    For best quality, divide by 300ppi.
