  3. Yes. I killed it, leaving only the better one: Thanks, David. Excellent image, although too saturated for my taste,
    particularly the green. Wouldn't have known it was HDR unless you'd said,
    which is how it should be (for me).

    Cheers,
    David

  4. That may be a very famous machine indeed.

    http://en.wikipedia.org/wiki/MUMPS

    If you have any more memorabilia, particularly such excellent
    photographs, and particularly with some of the people involved in 'em,
    I know a museum curator who would be very interested.

    I remember reading about that neurological work when I was working at
    DEC in the 1970's. I had a short gig doing software support on MUMPS
    while I was there. (mostly it was left to smarter people)

  5. I don't think there was MUMPS done on that machine, but I don't really know.
    Apparently the LINC from the Eye and Ear Infirmary is at the MIT Museum.

    But I only have a couple of other photos from father's work, and they're not
    particularly interesting. Said curator is welcome to that photo if they're
    intertested. (I'll look again, but I don't think there's anything else.)

  6. OK, thanks. I'll settle for sending him the link to your photo.
    He already has a sort-of working PDP-7. If your father's machine were
    not the one used to develop the first MUMPS there is not much point in
    looking any harder.

  7. Thanks for that. I've been off the photography for about a year; a cataract
    operation in one eye has me having different color balances left (warm) and
    right (bluer) and unsure about colors. Yuck. But I'm fed up with not doing
    photography. I did gunch up the saturation/vibrance, so it's good to know I
    overdid it.

    (Maybe I'll rethink the saturation/vibrance again, leaving yet another dead
    link in cyberspace.)
    But, uh, sorry for the too many subjunctives in there. "This is an image
    that I would have thought might have needed to be HDR" or the like. Which is
    to say, it's not an HDR image. It is hit fairly hard with negative exposure
    compenstaion and highlight rescuing to get the highlights more reasonable
    and then a lot of fill light to open up the shadows. But it's just one 5D2
    ISO 200 frame.

    Please don't take this wrong. Try working in BW until you get
    comfortable again with color.

    Thanks. I don't think fill flash would have covered a lot of area,
    however. Also I was pretty far off shooting with the 135mm.

    Not sure on the overall value of that exercise... I really want to play
    with multiple images to get a broader range of light reasonably displayed.

    :
    : Tokyo is 13 hours ahead of EDST. eg. when it's 02:00 there, it's 13:00,
    : the day before, here (eastern seaboard).

    Yup, pretty much what I thought I said: 13:45 + 4 hr = 17:45 (Greenwich);
    17:45 + 9 hr = 26:45 = 02:45 the next day (Tokyo). And 02:45 Tokyo time is
    within a few minutes of when the Exif data tells us David's picture was taken.
    Am I missing something?

    Color balance is highly subjective under the best of circumstances. Just find
    the color temperature that looks best to the right eye and the c.t. that looks
    best to the left eye, and split the difference. ;^)

    Nope. I got it backwards!

    Well, it doesn't have halos.
    I'm surprised it worked pretty well here.

  15. Thanks for that. I've been off the photography for about a year; a
    It's so personal, David. I've set the saturation on my Nikon to
    "Neutral", and my new Sony Bravia TV to "Theatre" mode, and am much
    preferring the results to most of what I see. The colours look natural to
    me. Colour balance doesn't worry me much, and I would have thought that
    the brain would equalise any differences. Oh well! I may be due for a
    similar op in a few years, I am told.
    I was saying it didn't look like an HDR shot, so my feeling was correct.
    Thanks for the confirmation. Appreciate the point about highlight rescue.

    Cheers,
    David (Edinburgh)
