Turning Off the TIFF Mac/PC Save Option?

    Using PS6.

    For years, every time I save a TIFF file I'm prompted to choose
    between Mac and PC format. I use a PC exclusively and have no reason
    to save as Mac and never have, yet it asks me every time. Other apps
    assume you will "Save As" if you want some special format.

    This is very annoying. Is there a way to turn it off?

    Make an action with your choice already entered and use that. It's not a
    special format by the way and it makes no difference which byte order
    you choose.

    Is there any speed benefit in using the TIF Byte Order that corresponds
    to your hardware platform?

    No. As I understand it this is a leftover feature from old times when
    certain programs needed to have a certain byte order specified to read
    tiffs.

    Check out this info which might not clear thigs up but is kind of
    interesting anyway.

    Then I wonder why Adobe forces everyone to go through an unnecessary
    extra step every time you save a TIFF file?

    Well you don't have to save as TIFF you know ;-)....so Adobe isn't
    forcing anything. They are ensuring Backward and Other System
    compatability...it's not a bad idea, although in your case it may be
    inconvenient.

    No. As I understand it this is a leftover feature from old times when
    Kind of. It's actually a leftover from the days when writing 16-bit data needed
    to be done in a way that corresponded to the "byte order" of a given processor.

    Some computer processors--most notably, those from Intel--are "little-endian"
    processors. That means, when the processor stores a two-byte number n memory,
    it stores it *backward*--that is, little-end first. The number "1000" is seen
    by an Intel processor as "0010." The number "1492" is "9214" to an Intel
    processor, and the number "12345678" is "34127856.". Every pair of digits is
    swapped with the pair to its right.

    Intel does this for historical reasons; their first 16-bit processor did this
    because it was easier to keep certain architectural features from the early
    8080 that came before it. As a result, even the Pentium 4 processor has certain
    quirks that trace back to the ancient 8080.

    Other processors, like those from Motorola and other processor companies, don't
    swap the digits. "1492" is stored as "1492," not "9214." These processors are
    "big-endian"--the big part of the nummber comes first, as it does in normal
    human-readable writing.

    The TIFF standard allows numbers to be written in little-endian format so that
    programmers who write software for Intel processors do not have to go and
    manually swap the numbers around when they read the TIFF into memory. Adobe
    calls the byte-order format "Mac" and "PC," but they should be called "Intel
    (little-endian)" and "everything else." The so-called "Mac" format means
    nothing more than "Record the information on disk in a normal order, without
    swapping all the pairs of numbers around."

    Then I wonder why Adobe forces everyone to go through an unnecessary
    Because the option is a part of the TIFF format, and some ancient TIFF readers
    for Intel processors can't read a natural-order (big-endian) TIFF.

  9. It's not unneccessary, because it's also the step where you can decide
    if you want to use compressed or uncompressed TIFF. After you have saved
    your file once, you will not be bothered with this dialog on subsequent
    saves.

    Holy Crap! Ed Hannigan?! You're *the* Ed Hannigan? Cool...

    You do some great work man, no lie. I grew up reading a lot of the comics you've drawn. You're one if the guys I used to copy when I was a kid to try to draw my own comics. I checked out your site...is the 'Artwork' section ready yet? I clicked on it and didn't get anywhere..anyway do you have any upcoming work with Marvel or DC or anyone?

    Regards,

    At his web-site, did you notice that not only do the letters of the menu
    roll-overs "squat" when activated, but the shadow moves a little as well
    to look more realistic? Maybe that's a common thing to do, but I've
    never noticed it before. You gotta love attention to detail.
