    But that was prior to 2005.
    Could easily ... could ... . You are speculating. Neither of us know.
    I've just tried it again and it still works for me.
    I know it is. But the RGB spaces he refers to below aren't likely to
    be.
    But conversions are always needed - from whatever color space your
    image uses to whatever it is that PS is using at the time. And then
    when you output the image you have to convert from the Adobe colour
    space to that of your output device.
    The clearest indication that I can see is on page 16 where it
    specifically refers to the Adobe CMM's use of tags, which tags are
    intended for the conversion of images to Lab. That doesn't necessarily
    mean that Adobe is working in Lab.

    If you will be happy with multiple sources then my earlier suggestion
    that you read the thread should be sufficient.

    Not to me, but I've already said that.

    For all practical photographic purposes there is no visible differences.
    Alan Browne has posted some examples in alt.photography. I went a step
    further, using Alan's images I applied a small curve adjustment in LAB
    that should have brought some of the darker areas into a portion of the
    LAB color space that is outside the gamut of the RGB space. I converted
    the LAB image back into RGB, and saved it together with a copy of the
    LAB image. nospam was invited by both Alan And myself to duplicate the
    experiment, and has given nothing but transparent excuses for his
    failure to post a duplicable experiment.

    Did you expect a rational answer. He's asicaly telling you to read a book.

    Well, there are all sorts of secondary questions about black point,
    rendering intent etc with such conversions. But my point is that Lab
    mode is surely not the only mode PS which requires color conversion
    and I can see no reason why that conversion should be any more lossy
    than any of the others.

    I have read the thread and can find no such sources, which is why I am
    waiting for you to substantiate your claim.

    I'm waiting.

    There are none so blind as those who will not see.
    Patiently, I hope.

    There are none so full of shit than those that refuse to support their
    claims.
    No, knowingly. I knew you wouldn't support your claim, you never do. You
    just make claims and then claim that others are blind if they don't agree
    with the claim. It's your thing. That's why you have no credibility.

    For me, such things are important, which is why you see me *always* support
    my claims, like earlier, when Tony called me a liar when saying that the
    Colonial store consisted of some 70% "hobby stuff", I then proceeded to
    prove that I was pretty much dead on with that estimate.

    That's how you support a claim, not by telling Tony that he's blind if
    don't know it.

    It isn't. it's a lot less lossy. Some of us like working in LAB mode,
    for reasons previously stated. To minimize troll comments, let's just
    say for certain operations I prefer to work in LAB.

    The figure is a patently false statement. Claiming that the store is
    "70% hobby stuff" is a claim about the store's inventory. Unless you
    did an inventory, and counted the items, you have no idea of what
    percentage is "hobby stuff".

    It can be contended that the store has a 100% inventory of "hobby
    stuff" since camera products can be "hobby stuff".
    No, you support a claim by making a sensible claim in the first place.

    No it isn't, troll. It's a claim about how much floor space is devoted to
    "hobby stuff". Do you know how I know? Because I made the claim. That's
    how. Stop trying to tell me what I mean. And learn to read English.
    Even so - by counting single items, the store is probably a lot more than
    70% "hobby stuff" given the size of all the model kits stashed on top of
    each other row after row.
    Semantics, the idiot trolls last resort. You found out that I was correct
    about my claim so you have to argue on and on and twist things as much as
    possible so you can fool yourself into thinking that your explicit claim
    about me lying wasn't incorrect.

    You were caught making an incorrect claim, and you REFUSE to admit it, like
    you ALWAYS do. Since I started to talk to you, you haven't admitted to ONE.
    SINGLE. ERROR. ever. And you've made *plenty* as I've shown many many
    times.
    WTF? How dumb are you? You can't support a claim by making a "sensible
    claim", how brain damages did you get when the truck hit you, Tony? That's
    one of the dumbest things you've, and we all know you've said some really
    dumb shit. That goes staright into the quote file

    Oh, so you meant what you didn't say? At this end, all that can be
    done is work with what is actually said.
    Yes. I'm sure. Balsa strips are probably inventoried individually.
    What the size of the kit is has little to do with percentage of
    inventory that kit represents. You seem to confuse "quantity" with
    "size".

    Or, is this another place where I'm supposed to know what you meant
    because you wrote it, and not take what you wrote as what you meant?
    And yet most of your arguments are based on defending your bumbling
    attempts to write a sentence that means what you want it to mean. Your
    failures in lexical semantics are the source of much of disagreements
    here.
    If your claim is sensible in the first place, the support for it is
    often self-evident and certainly easier to provide. The claim has to
    be sensible to be supported because your support has to relate to
    actual claim made, not the non-sensible way you originally made the
    claim.
    No truck hit me. Let alone a Volvo.

    I'm not saying there are no differences - there are no VISIBLE
    differences - even using the difference or subtract function to pull
    them out. If there are differences they are at such a small level as to
    not show. I'd venture that it would take manyconversions to maybe make
    something show up or drastic colour changes in the image in one mode or
    the other - and if you're doing that then little changes due to
    conversion are not worth mention.

    The fact that I'm working at 16 bit is important - whatever changes
    occur (if any) occur in the low order bits - and that will not show on a
    monitor and definitely not in a print.

    A visible difference? None at all. None in the images. None in the
    difference.
    Show your results.

    Show an image. Show a visible difference.

    Stop making claims without supporting evidence.

    No, I meant what I said.
    There you go inventing things again. Why can't you read English?
    If you're confused, like you always are, ask me. If you continue to
    interprete stuff like a moron, be prepared to be laughed at again, and
    again, and again.
    More lies from Tony.
    But that's not what you said, moron. You said, and I quote your idiotic
    rambling here:

    "No, you support a claim by making a sensible claim in the first place"
    - Tony "Andreas Skitsnack" Cooper

    Yeah, that's how stupid you are.
    Keep telling yourself that.
    It must have, you went from rambling troll to hypermoron in the course of
    like two days. Nothing you say ever make any sense what so ever. You're far
    beyond any help now, you're stuck down in troll drain forever. I would pity
    you if you hadn't been such an asshole on the way down.

    There should be no argument about any of this. It's obvious from first
    principals.

    I have yet to see your proof of discernible (visible) changes in
    conversion from RGB to Lab in PS. Still in the queue is it?
