    I have an old version (5.0) of Photoshop. I can open Canon RAW files with
    Canon software and move them into Photoshop as a 16bit tif. The trouble is,
    in order to use the Photoshop tools, I must convert the photo back to 8 bit.
    I have noticed on just two shots that the image seemed to darken when
    switching from 16 to 8 bit. How much difference should I expect in a final
    print between a 16 and an 8 bit image?

    You shouldn't expect any difference but what you are probably seeing
    is the reduction in dynamic range when you drop to 8 bit.

    Honestly, if you are going to stay with Photoshop and want to work
    with 16 bit files then drop the $$$ on an upgrade to CS.

    Oh, and if you do upgrade I would also I would suggest purchasing the
    book "Adobe Photoshop CS 1-on-1" by Deke McClelland ($40.00 USD).

  3. Hey Deke! Is that you? Love your book. I have that and the Bibles for
    InDesign and Creative Suite....but while those books are always open and
    help me do better what I know how to do...the book that is teaching me
    important new concepts is Professional Photoshop.

    I shoot RAW and convert to 16 bit...but edit mostly in 8 bit....lots of
    tools won't do 16. But more and more are.

    Sorry - not Deke, nor do I have any affiliations with him, just a
    longtime Photoshop user who really thinks Deke does a good job with
    his books and tries to save others all the money I wasted finding good
