    When your first comment about her presentations refers to entertainment,
    you are doing a highly talented person a grave disservice.

    Most talented photographers I respect agree with my statement. BTW
    instead of pulling statements, "out of your ass," do an experiment.
    Surely you can do a test image and post the results here.

    Write an unambiguous and accurate statement.

    Maybe so but you have yet to explain how you think it works and how
    working inLab mode requires twice as many conversions as working in
    RGB.
    As above: please explain why.

    This is the third or fourth time of asking. I'm not trying to argue.
    I'm trying to find out.

    As opposed to the following example where an RGB input is converted to
    CMYK for output to a printer and back to RGB for review on a screen.
    This requires numerous trips backwards and forwards through the Adobe
    (Lab) colour engine.

    RGB(source) ->Lab (Adobe engine space) ->CMYK(printer) -> Lab
    ->RGB(screen).

    This a trick which you have tried several times already. Nospam issues
    a cloud of statements, somebody eventually works out what he is trying
    to say and summarises it in a single concise statement, you then
    challenge them to tell you where nospam actually said that.

    Well of course he didn't actually say that. The particular meaning
    congealed from with a cloud of diffuse verbiage.

    Apart from that, effective vs ineffective is a matter of relativity.
    Further, the two points which you question are summaries which have
    been put to nospam as questions. Neither of them has to be true: it's
    up to nospam to choose.

    'Effectiveness' or 'ineffectiveness' is a matter of relativity.
    And compared with your post-Lightroom work flow it was relatively
    ineffective.
    I can accept that.

    nonsense. my first comment was a recommendation of her books.

    you are as usual, wrong.

    then they're not as talented as you think or they don't understand what
    they're doing any more than you do.

    andrew rodney, chris murphy, jeff schewe and bruce fraser, all of whom
    are *very* well respected in the industry and have authored one or more
    books on this very topic have commented on more than one occasion about
    the drawbacks to a lab based workflow.

    take your own advice.

    you said it's not a conversion but it's a conversion. you haven't any
    clue what you're talking about.

    i quoted from andrew rodney's book which explained it.
    the answer to that was given in what i quoted.
    then read what was posted.

    given that lightroom didn't exist then, what i was doing was the most
    effective workflow at the time.
    however, at the time, there was no lightroom so that's not relevant.

    what i did then would be ineffective now because there are much better
    ways to do things.

    in the future, lightroom may be considered to be a clunky and
    inefficient workflow after something new comes along, but until that
    happens, lightroom is about the best there is for the majority of
    users.
    that's what i said originally.

    I usually have only one round trip, two at the most.

    It is intellectually dishonest to snip to change the meaning. There are
    several phrases that describe doing that. theone that best fits, when
    you snip incompetently, is.
    Stupid asshole.

    maybe one day you'll take a one-way trip.

    i didn't snip anything.

    you are once again lying. or should i say, still.

    I won't repeat the first time I asked but the second time it came up,
    it went like this:
    internally, but that's not the same as making a conversion of
    the image twice."

    My questions are intended to learn why you think working in Lab mode
    requires making a conversion twice. Your quotation above doesn't
    address that question at all and certainly it doesn't explain why you
    think converting an image to Lab mode in PS needs twice as many
    conversions as leaving it in RGB. After all, PS processes the image in
    Lab mode. All the conversion to Lab mode actually does is give the
    user a set of controls which work more directly on the color engine.
