John, you are right, techically it *is* a very good photo. I gave it a 7. The only, basically insignificant, technical comment i can see as relevent to this image is that the white is "whiter" or better lit behind the blade than in front. The lighting on the blades though (which is what really matters) is perfect.
So it really came down to personal preferance - when i first saw the image i thought, i wish he had gotten closer to the blades, maybe no white at all - so we could be emmersed in the black and silver waves. I stand by my first impression. I dont know what this talk is about stray hairs? Someone must have super sonic eyes, because i cant see any!!
This wide a view was probably used in order for viewers to be able to identify the object however the pattern of the blades is very interesting and I feel a closer crop would add to that interest.
The pattern of this image really caught my eye. I like the placement of the blades. However, the top blade is not spaced as even as the others are. Nice job in making a plain saw blade interesting.
