An odd picture taken whilst experimenting with using a macro tube on my 70 – 200mm L series.
Turns out with all my macro tubes on you have to have the lens pretty much touching the subject!
I was also trying a technique a photographer suggested of setting the camera to manual, the shutter to 1/250th, the aperture to full open (in this case f2.8) and the I.S.O. to auto.
The resulting I.S.O. turned out to be 1600, the maximum I allowed in auto I.S.O.
Taken with the trusty Canon 60D
