good bad & ugly from the same jpg

  1. I'm comparing different functions, like various auto-fixes and sharpening,
    in different image editing software, but the extraordinarily frustrating
    thing about it, is that each of these adjusted images looks DIFFERENT in
    different image viewers (on my 19" Viewsonic A90f)..

    The most radical of these is Irfanview. If an image is sharpened at ALL, it
    tends to look grainy and mottled in Irfanview.

    The same image might look decent but not attractive in the picture viewer
    built into Windows, but it had looked better in the JASC Paint Shop Pro
    preview where it was edited, and then might look GREAT in Compupic
    (thumbnail manager and image editing program; though Compupic seems to make
    lots of images look great).

    But I'm trying edits in different programs (I-correct, JASC, Roxio,
    Compupic) and depending on which viewer is used to view and compare the
    images, some look better in some viewers, others look better in others,
    and lots of them look totally defective in Irfanview.

    What should a person use as a STANDARD for viewing images onscreen?

    Not clear if it's other people viewing the images that is your goal or
    just you.

    If it's other people the answer might be IE!!!

    You don't say what size the image is and what size it is being displayed at
    on screen. If for any reason it is not being displayed at full size, then
    the program you are viewing it in needs to resample the image to the
    displayed size. Various programs use different algorithms to do this with
    varying effect. To make a valid comparison you need to view the images at
    full size so each pixel in the image is displayed as a single pixel on the

    You also need to be aware of any color management the program may or may
    not be doing.
