Well you got close.... unfortunately there isn't much else about this that appeals to me - there is a little too much mess on the corn for this to work I think. But good display of technical skill to get this close and in focus.
Sure, I think of yellow when I think of corn. Fits theme nicely. This is a nice tight shot which shows adequate detail. DOF is a bit shallow and using a smaller aperture would have helped here. Still, one of the few photos that actually meet the challenge theme. 7
