I like macro photography, and so far I have had to make do without a macro lens. resorting to dioptre lenses, reversing one lens onto the front of another, or more recently using a 2x converter with the glass removed. One day I will get a proper macro, I hope, a Pentax 100mm macro lens, weather resistant too.

This shell was taken using my Pentax 35-70 macro zoom on a macro converter lens (like a 2x converter except you spiral it in and out).
However when doing macros the depth of field is inevitably very shallow, but I found a program that can get around that (to some degree)

CombineZP

You take a series of photos and change the depth of focus slightly on each one ( a tripod is handy). Open CombineZP and load the photos into it. It will then stack the photos and work its magic to give you a photos with a much larger depth of field 🙂
and its a free program too

The image was turned to black and white in GIMP (free too) using channel mixer
