HDR photo doesn't open properly from file.

    Question: I'm using Photoshop CS2 on Vista. I select Automate | Merge
    to HDR. After merging is complete, the photo looks fine. I'm using
    three bracketed photos (+/- 2 EV). However, if I use the Rectangular
    Marquee Tool to select an area from the HDR photo and paste that into
    a new document, I get what seems like only the +2EV photo. I then
    save the merged photos as an HDR file. The photo still looks fine. I
    close the photo and open the HDR file. It opens what seems like the
    +2EV photo rather than the merged photo.

    Any ideas what I'm doing wrong?

    Did you "flatten" the final image?

    After the photos merge, most of the options are grayed out, including
    flattening layers.

    What is the bit-depth of the image?

    32 bit, which is recommended for HDR.

    32-bit support in CS2 is very limited.
    The only thing you can do is adjust exposure (in a few different ways)
    After you merged to HDR you have to reduce bitdepth (16 or 8 bit) to enable
    It just doesn't work otherways.

    Indeed it is, however for this version you must degrade the bit-depth to
    more CS routines.

    It ain't your fault. It should tell you that.
