I'm playing with my new 60mm macro lens today. It will take a bit of practice, but I like the results so far.
My general practice is to convert many images to monochrome to see what I get. I'm getting better at determining which images will work and which ones won't. I like the color image here, although I was surprised at the amount of contrast and detail I got with this monochrome conversion. This is definitely rather abstract in either case.
