    Here are some sample pics of the DiMAGE A1. All shots were done in RAW mode,
    usually at ISO100, see descriptions for details. The newsgroups are full of
    discussions where often people, who never held an A1 in their own hands,
    heavily critisize noise and image quality of the A1. All images are captured
    with the DiMAGE A1 and had maximum 1 minute post-processing - only automated
    and almost unattended batch processing like
    RAW->RGB48Bit->Adjustments->color space conversion->RGB24Bit.

    I saw the photos, and got a bit disappointed...........i did not notice any
    noise....... ;-) I think these kind of photos aslo should be a part of a
    standard procedure in tests on ie. Dpreview... The only example i've seen
    is in the review of Oly E1.


    Did u use Minolta or Photoshop for the RAW convertion? Also if u did
    photos, or any kind of manual asjustments on these phots?

    I would be interesting to compare the same shot made with best JPEG and one
    taken with RAW, to compare the differnce. It would aslo be very
    interesting to also see results form ie 400 ISO (these will of course be
    much more noisy.....it will e from most cameras... )

    it would also be interesting to know what software u used for the RAW
    convertion

    Did u use Minolta or Photoshop for the RAW convertion? Also if u did
    The original Minolta DiMAGE Viewer Software. It's not bad, supports the
    Adobe RGB color space, simple batch processing and 48 bit TIFF (16 bit per
    color) are provided. After that fully automated noise reduction with TIFF 48
    or 24 or JPEG as output. Some of the shots got a simple contrast adjustment
    with the tone curve. You can definitely make much more out of the images,
    but I wanted to keep the manual invested time per picture within seconds.
    Will try to make some sample pics in ISO400 too, of course they will be more
    noisy, but I hope I can "disappoint" you even there :)

    I just shot a test scene in ISO 100, 200, 400 and 800. You will find them at
    the site all in full size version

    I would be interested if you used the NR feature of
    Hi Dave,
    I just added the EXIF data (aperture and shutter) to so ISO test shots. I
    generally have the NR feature switched on, because the information I have
    from Minolta is, that the NR feature first starts at shutter speeds of 1"
    second and longer. So as far as I know, it has no effect on normal shots.
    With NR on, I never had the so called fosi-bug with the bad hotpixel at
    nightshots with long shutter speeds, which are so heavily discussed in
    internet, maybe these guys have switched NR off.

    My experience told me, that the A1 has a not optimal standard settings. It
    makes a lot of sense to once go through the menu and change several settings
    and save them to one of the user profiles. So I have one for Quality (RAW,
    ISO100, SingleShot, Flash -0,7, fader cross, FFP, etc.. and another one for
    snap shots or actions (JPEG XFINE, ISO AUTO (100-200), Fast Series Shot
    Burst, fader cross, spot measuring, auto 11 point 3D AF with grip sensor on
    and predictive AF etc.). I have others too, but these two covers most of my
    pictures.
