Thanks for the compliment on the Moss with water drops. It's a wonder I
didn't get water in the camera, it was rather wet that morning, and cold for
me.
I practiced starting with shooting coins on my desk top, and then wondering
why I even touched those dirty things.......but good outdoor light is
preferable.

Subject: [OM] Re: More Experimentation
Scott's got some great images there to illustrate his point. The first
one (753) is truly gorgeous. But apart from distance and how to focus a
reversed lens contraption the principal rationale for using the lens
reversed is that it puts lens, subject and focal plane back into the
relative positions the lens was designed for. When a non-macro lens is
used normally the subject is farther from the lens than the image
plane... and that's what the lens is designed for. But in macro use
these relationships get turned on their heads since the subject can
easily be closer to the lens than the image plane. Reversing the lens
restores the normal balance of things and gets the angles of light beams
passing through the lens back closer to the original design criteria.
