    Hi all!
    I received 2 identical photos: pic01 (54 kb) and pic 02 (141 kb).
    I opened them in Photoshop CS2.
    pic01 was 5,125 x 6,667 inches with a resolution of 72px / inch and 369
    x 480 px for a total of 518,9k
    pic02 was 1,55 x 2,125 inches with a resolution of 200px / inch and 310
    x 425 px for a total of 386,0 k
    When I view pic01 and pic02 together in Photoshop, pic 02 looks better
    defined, even though I change it to the same dimension as pic01 and its
    resolution (witth resample image off) is down to 60,488). The photo,
    however looks smaller even though they are both at 100% on screen.
    My question. Why does pic01 seems better with the numbers, but not as
    good as pico2?
    It seems that I should keep the second one instead of the first one.
    Please explain where I'm going wrong. Thanks,
    Marcel

    .... I forgot to add:
    pic01comes at 53kb when I received it and when I open Photoshop
    "picture dimension", it's 518,9k
    pic02 comes at 138kb when I received it and in Photoshop, it's 386k.
    There's definitely something I don't understand. Please set me
    straight.
    Thanks again and sorry for the double-posting.

  3. Probably the first is more heavily compressed than the second, assuming that
    they are JPEG.

    They are JPEG. You've got a point that I didn't think of. Thanks.
