software bundled with cam.. no good?

    I am wondering if anyone else have had such an experience. Perhaps
    attention will be brought and save other people's time. For nearly 2
    years, I have used the bundled software (Camedia Master 2.5) that came
    with the Oly C-3020 to do the most basic of things.. rotate JPEGs. I
    do very little post processing of my photos and I assumed rotating the
    image is a fundamental task standardized and LOSSLESS.. I am wrong. At
    first, I thought that vertical images take up less space simply due to a
    JPEG compression side effect. I came to realize that the bundled
    software cannot be trusted to even rotate JPEGs.

    So to caution novices unaware of this.. check to see if the software you
    use are lossless or not. Can anyone provide info on which manufacture's
    bundled software has this "flaw" ? I hope it is just the older
    generation of cameras/bundles that do this.. since I think it is

  2. JPEG is lossy.

    < JPEG is lossy.

    I realize that JPEG is not the ideal format, but it suits well for
    viewing and small prints. The problem with loss in rotation is that
    there are widely available applications that have "lossless" JPEG
    rotation. It's also easier to work with smaller files (JPEG vs TIFF)
    since they do write to camera memory faster, and saves time uploading
    online, especially for slower connections or connections with slow
    upload speed.

    There are a bunch of ways to do lossless rotation of JPEG images.
    Google for "lossless jpeg rotation" (sans quotes) to find some.
