    You've opened Pandora's box, though. The next challenge is stacking
    images for more DOF. More software, a special rig with a geared
    platform, bellows... it'll never end! :)

    Whose reversing rings do you use?

    Woot. I'll have to backtrack to how you put the lenses together. I've
    got a reversing ring for my 50 mm lens, but no step down rings for the
    105 lens.

  4. Yes, I have thought about the geared platform and bellows, but I think they
    will hamper my shooting style since I shoot handheld. I'll probably pick up
    a set in the future. The shallow DoF is hard to work with, but I don't
    think software will help when shooting moving insects.
    Just a cheapy I got on eBay.

  5. Now, there is an idea for super kit - a contraption which automatically
    bracket-focuses at macro distances, with built-in stacking
    software...and all hand-held.

    Unfortunately, the bracket-focusing in macro work has to be by moving
    the whole camera/lens assembly; moving the lens relative to the camera
    (like the focus bracketing for normal distances found in some digital
    cameras) would be useless, as the image magnification would change too

    All you gotta do is hand-hold this rig. :)

    So you put the device between the camera and the tripod.

    On line, I've seen some amazingly unnatural shots by a Japanese
    photographer (didn't bookmark it but some of you may know who I'm
    referring to) where the depth of field seemed like matter of inches
    rather than the fractions of inches in most macro shots. A guy named
    Jeff Boyd ("The 2Belo") posted a link to them on his LJ, but I couldn't
    find it looking through quickly.

    (Macro, a world in itself).

    That's pretty wild. But I'm confused about his focus bracketing and
    stacking. I understand stacking when it comes to astrophotography but
    how does it work with different focus points?

    In a subject with a lot of depth are you just getting different layers
    into focus? But wouldn't that cause the whole thing to be blurry when

  10. AIUI, the stacking programs select the sharp bits from each "slice" and
    combine them together to give an overall sharp image.

    A similar technique is used in some kinds of microscopy. You use a
    pinhole & a ton of light, & all the out of focus stuff becomes
    essentially invisible, so each image in the stack is like a thin slice
    of the subject. I'm guessing that this is something like that.
