My wife loves to grow stuff on the balcony. This year we got some beautiful, red tomatoes and chilies. The complete set of photos is located at: http://kansala.kuvat.fi/kuvat/Antti/2011-09-05+Chilis+and+macros/
I just received a wired extension tube that I had to test. The macro photos are shot with Nikkor 50/1.4 lens with a 36mm extension tube. As the sun was setting, I had a chance to test a 5-led head lamp as a light source attached to the lens hood. All photos from the mosquito shot onward use it.
