There are two distinct techniques you can use for this. Both are
demonstrated on the February PUG. I think it is Wiliam Robb's that
demonstrates, with his picture of an aphid, reversing a (macro?) lens
on the front of a telephoto. My own submission, of cyclamen coum,
demonstrates the somewhat simpler technique of a reversed wide-angle
lens and extension tubes.
For my own photograph, all that was required was a 49mm "reverse
adapter" (male 49mm filter thread + male K-mount flange), manual
extension tubes, and a 28mm lens. The accompanying text lists all
the apparatus I used. Lens reversal is recommended even for an
ordinary macro when using extension tubes to go above 1:1
magnification.
Modern camera bodies with TTL flash control and automatic exposure
makes taking such photos quite simple.
