    Nothing on TV last night, so decided to have some fun - macro
    style. I've seen this done before, but never tried it myself.

    Just trying to get some abstract crazy colouring. I had no idea
    what colours were going to be created. And I wasn't expecting
    that weird halo sort of effect. Shame about the dust. The DVD
    looked pretty clean to the naked eye, but 2:1 lifesize and flash
    shows it up unfortunately.

    All shot at about 2:1 lifesize with full set of Kenko extension
    tubes and 100mm macro lens. Click the images for larger views:

    Hello Troy -
    did you see this?

    It is in German but most of the fotos are self explaining.
    You will find many very good fotos even of drops under Water!

    Thanks for the link, Udo. I haven't seen that site before,
    although I have seen similar shots. Next time I am bored, I'll
    give that a try. :)

    Again, you have piqued my interest, Troy - these are cool.. I sort of
    like the dust - somehow makes them look organic or something, although
    the rather large amount does cast aspersions about your clean room hi-fi
    environment...

    I have some rather interestingly 'damaged' cd's that might become rather
    photogenic when treated thusly. I might return to this thread later..

    :) Thanks mate. Not too many bugs around for macro shooting.
    And this can be done in the warmth of your own home.
    Ha. Actually I'm pretty anal about keeping my CDs and DVDs
    clean from dust and scratches. This was a DVD that hadn't burned
    correctly and I had salvaged from the bin so I couldn't
    potentially damage one of my real DVDs. ;)
    Look forward to it. I want to try some different lighting angles
    to see if any other colours appear, or if it's always the same.
    This was just with my normal macro rig, flash top left of lens.

    Cool. Must try.

    Hmmm ... get a black light... never know... (and/or simply add a gel to
    your flash head).

    Good idea! I've got hundreds of them unused to date in a Rosco
    swatch pack. And the lighting at different angles must give
    different effects. Let's play! :)

  8. Hi, Troy.

    Coincidentally, the other day I got my reverse mount in the mail, and
    spent a night playing with that and my 18-55 at 18. This was part of my
    testing, not an attempt at art!

    http://blinkynet.net/stuff/reversed_lens_needle_3333.jpg

    Normal sized needle and thread. Background is silk.

    It was fun experimentation and my first macro[1] attempt with the D60...

    ....then, as I was heading for bed I spied a spider in the bathtub. I
    chased him around for a while. He won. :)

    [1] Shooting a ruler, my first testing, showed I was getting 4:1.

    Pretty impressive detail.
    Get your fitness up and go shoot more bugs. They're all over the
    place in your hemisphere at the moment. I'm jealous.
    Wow. Better mag than I would have thought. Can you control
    apertures reverse mounted?

  10. For a $29.99 reverse mount (and Nikon makes precious few accessories in
    that price range <g>), I was quite pleased. Yesterday I picked up a
    remote shutter release. Probably the only Nikon object that's even less
    (about $16). How do they stay in business?! Oh, yeah......cameras and
    lenses that cost as much as cars. That's right. :)
    I will. I'm jealous of your macro lens. :) Yes, I've been shopping. As
    for less-magnification macro-ing, at the 55mm end of that lens, still
    reversed, the ruler shots show I'm getting 1:1.25 .

    Quick story. With no live view, there was no way I was going to get a
    look at what I was shooting when I was bent over the tub with the spider.
    Despite the DOF (and scene size) you know I was getting with macro (I
    cheated and went to the longer end of that lens, but it was still
    reversed.) So I actually chased him around for five minutes with "iron
    sights"; i.e., just pointing the damned camera at him and pulling the
    trigger. :) I actually got two shots of him that way! Not good, but
    *considering how I was shooting*, I was lucky to get *anything*. :)
    Here's one of them:

    http://blinkynet.net/stuff/grab_shot_1.jpg

    Not a big spider, either :)
    Extremely crudely. :) I have to manually adjust the iris with my finger
    on the lever out at the front. If I'm holding it open (default is closed)
    part way, I have no way of knowing the the fstop, but I did do some of
    that -- you can get a *rough* feel for the iris position, kind of the way
    you know how far to turn on the sink faucet without looking at it. For my
    testing, I had enough light that I could frame and focus wide open and
    let it stop down all the way (f22 at the wide end of that lens) for
    shooting.[1] That's how I did the needle and thread. (And that's an
    uncropped shot.)

    [1] On-camera popup flash, firing a Vivitar 283 strobe on each side
    of the subject via a Wein Peanut optical slave trigger for each Vivitar.

    Don't I know it :(
    Sigma makes a Nikon mount 105mm macro lens for around US$390. I
    know it's cheaper than my Canon 100mm, but just as good if not
    better. Don't know about Nikon macro lens prices. Do it :)
    Try to keep the aperture around f/9-f/11 seems to be the
    consensus for around 1:1 macro shooting to get the sharpest
    images. Much higher than f/16 you get diffraction softening at
    close working distances. Definitely wouldn't be shooting macro
    at f/22. I'm sure your reversed rig will perform similarly.
    Test shots please :)

  12. I've spent hours reading reviews and test of that lens and a couple
    of others. I probably should have spent that time making $390. :)

    It'll do 1:2 without help, IIRC.
    The reason, IIRC, why small sensor cameras don't even *offer* much
    smaller than f8 or something like that.
    I'll try that. Blindly -- remember: no indicator and a short-throw lever. :)

    I'll let you know what happens. I'll set up another run at the needle and
    thread test.

    No - it's a "true" macro lens. It will do 1:1. If you put a set
    of extension tubes on as well, you can get around 2:1. Then
    stack teleconvertors etc and it goes on and on...
    Oh, here come the excuses and he hasn't even tried it yet :)
    Sweet. I love recruiting macro photogs to the dark side. >:)

  14. Great. I must've conflated it with one or more of the other lenses I was
    looking at. I was looking at cheaper stuff, too. Probably the 1:2 lenses
    were the under $200 jobs. Of course the Sigma is half the price of the
    equivalent Nikkor.
    Oh, but I did try mid-range aperatures. Remember me saying it was a hard
    to hit them consistently? I probably forgot to mention how thrilled I was
    to discover that I could make pictures with the spring-loaded f22 default.
    :)
    You ol' debbil man, you.

    But that's okay -- I love experimenting with hardware.

    Wait. Is "dark side" appropriate in this context? I think probably not. :)

    It also occurred to me that some food dye in the water might work with a
    clear strobe...

    Must play. [ must work ].

    Use glycerine, either neat or mixed in the water, gives a much better
    effect.
