This flower is most often seen along roadsides and other disturbed areas where moisture is present. All of the below photographs were taken by the roadside.
Canon 40D: 100mmF2.8 Macro
The macro shots were taken by resting the camera on a "bean bag" for support. In this case some type of grain such as wheat was used, but most people take a small bag and fill it with beans, hence the name "bean bag. This makes a passable substitute for a tripod for low level shots, when one must lie on the ground to get the correct angle on the subject.
I was thinking about purchasing a tripod especially for this type of shooting as my Gitzo with Wimberley Head is not the right tool for this type of shot, but then I remembered an old Slik U212 that I no longer use and modified it for macro photography. I have had no chance to use it yet. If it works well, I will post a picture of it and give some more details.
