These needle photos were taken specifically for the macrophotography challenge in photographers. They are not, however, macro photos. A macro photo is, technically, one in which the size of the image on the sensor is greater or equal to the size of the object. This is not even close to that, considering that the CCD in my camera is 1cm on the diagonal.
I am heartened by the fact that most of the other photos for the challenge were not technically macro either.
