    Default camera phone vs DC vs DSLR


    some queries about camera phones:

    (1) i have tried 2 sony phones, even with the cybershot camera phone, and i noticed that the pictures taken show 72 for both the X and Y resolutions when viewing its exif. does it mean the resolution is low and pic can't be printed properly by the shop?

    (2) how to take pics with a 3MP camera phone and use it to be printed out by the shop at 4R size? i mean how to set the X and Y resolution to be 300 for both ?

    (3) the exif of pictures from sony cameras like DSC-W1 and its camera phones like K800i show that the Xresolution and Yresolution are at 72 while those pictures taken by nikon DSLR show the X and Y resolutions at 300. what is the implications of these numbers?

    sounds like the output resolution or what we commonly call the DPI.

    in simpler terms, it is like the volume of a mass. a 20g weight is always a 20g weight, but you can shrink to 1ml or expand it to 1L volume, but it is still a 20g weight.

    this DPI thing is how much we change that volume.
