Thread: heavier is better ?

  1. #1

    heavier is better ?

    i do think i have below some every ridiculous questions, but just help answer if you guys don't mind :-j

    1. why the the X megapixel camera (14.2 for example), brings out just < X MP ( 5 M ) pictures :-?
    2. and why, while shooting the same scenes or things, the 10Mp camera can sometime gives us 7MP pic rather than the 5Mp pic of the 14.2 Mp camera.
    3. the 7mp pic is heavier; but is it better in quality compared with the 5mp one?(100% view). if not, then, what is the reason for that it's heavier ?

    Hi phiduypdn,

    Could I first ask for a first name please?

    Somewhat belatedly, welcome to the CiC forums.

    I think we may be losing something in the translation here. The other thing that isn't helping is mixing up MP (megapixels) and MB (filesize in megabytes), they are not the same thing.

    1) This is why 14 MPixel camera can produce only 5 MByte files (probably jpg).

    2) I think you're asking why some files are larger (not 'heavier') than others?

    However, without knowing whether you are talking about the same things when comparing the two different cameras; for example, whether one is set to shoot at a lower than normal resolution (e.g. 3,200 x 2,400 pixels instead of say, 4,800 x 3,600 pixels), or whether one is set to shoot at a different 'quality' (e.g. Normal, Fine, Super-fine, etc.), it is very difficult to answer accurately.

    3) For the same filetype; e.g. both jpg, yes, almost inevtiably, a 7MByte file should give better quality than a 5 MByte one.

    I hope that helps,

    sorry Dave, it's my mistake

    yeah.. it's what i meant.

    2) I think you're asking why some files are larger (not 'heavier') than others?

    the cameras r working at their highest capacites
    3) For the same filetype; e.g. both jpg, yes, almost inevtiably, a 7MByte file should give better quality than a 5 MByte one.
    that's why i asked, Dave. my 10mp camera ( compact) produces up around 7Mb file. but other DSLRs' files are just about 5Mb :-? while they are 14mp or even more.

    I hope that helps,
    thankyou :-*
