Photoshop problem - huge "stepped" panos

    I have encountered some weird behavior of CS3. When using the photomerge
    command to create a pano from about 17 photos, CS3 chugs along for
    about an hour or two then after getting the pano assembled it either
    freezes up or it just shuts down (one second I'm looking at PS, the next
    second I'm looking at my desktop).

    The panos that I am making are very large. I am trying to stitch
    multiple DOQQ images (aerial images) of the Louisiana coast. They are
    ..jpg files and are each approximately 6800 x 7700 pixels. I finally gave
    up CS3 and stitched the images with PTGUI, which worked pretty well. I
    saved the image as a 20,000 x 20,000 (400 megapixel) .jpg, then opened
    it with CS3. Three times now, during different operations, CS3 shut down
    without any warning.

    I am running an Intel Q6600 processor with 4gb of 1066 ram in dual
    channel mode on an ASUS motherboard with two 500gb SATA hard drives in a
    striped RAID array and an additonal 1tb hard drive, both with plenty of
    available space.

    Any ideas what's wrong? Is there some limit to the image sizes that CS3
    will work with or is there some memory settings that I should be trying?

    I am trying to adjust color and contrast, label places and geographic
    features and then get a 60in x 60in image printed for my wall.

    PS: If you would like to attempt to stitch an image like this, the DOQQ
    images can be found at:

    Just out of curiosity, have you tried some other photo editing software?
    Maybe GIMP, orphanview, etc.

    I haven't really had time to do that but I plan to give the GIMP a shot at
    the editing over the weekend. Nevertheless, I would still like to find out
    if there is something I can do to help Photoshop handle a file of this size.

  5. I downloaded one of those 150 Meg TIFFs. It seems to be itself a
    stitched image.

    The limits of CS3 are 300,000 x 300,000 pixels, see

    so you have another problem. You could try increasing your page file size.

    Apart from using layers and transforms (eurgh), I don't think it has any
    built in functionality. There's various plugins, like Pandora and
    Panotools, but it all looks too hard to me so I stick with PTGUI..

    The pandora plug-in for GIMP does simple straight line panoramas. Beyond
    that, use the panotools.

    In the performance settings, I set the history states to "1" and cache
    levels to "1" and that seems to have helped. It still will not do the
    pano but if I keep the file no bigger than about 20,000 x 20,000 and be
    patient and, this is important, don't move the image window around the
    workspace, it seems to handle most functions except "Save As" which,
    along with trying to move the image window, will make PS instantly shutdown.

    PTGui is very user friendly with its control points.

    I tried a 6 shot HDR pano last night CS3 and AutoPano wouldn't touch
    it, put it into PTG it wouldn't do it auto, spent a bit of time on the
    control points and it came out fine.
