Excellent use of DOF on this one Mark. I think it might be more appropriate to title it Valve Train though. :-) Nothing quite like an old small block chevy tp peak the auto enthusiast's interest.

All the best,

Neil Thanks. I was not sure what it was. Thanks for clarifying

This is a really cool shot, I have always had a thing for the mechanical and technical stuff. I agree with the other comments on the grand use of DOF. The repetition is wonderful as well. I find the background to be a bit distracting however, (as I have seen other members on this forum do I will attach an edited example of what my tastes would prefer) allowing the subject to trail off into the corner may lead a little mystery, and subtracting some of the background would help in keeping the eye of the viewer within the image.  A slight crop would also allow the rule of thirds to come into effect placing that near rocker right on the line (approximately plotted with the white X's). Having the plane of focus on the right of the subject allows the eye to travel naturally for us western world folks. Just my two cents!

This is a lovely image, my comments and suggestions are purely for the academic aspect of the critique.

Joe.. thanks for the comments. I agree  about the background. I started to crop a bit but then i don't like that i am missing part of the last valve.  I will look to see if i have from a slightly different angle. I could just blacken the background a big. I am not sure the 1/3 rule bothers me a lot here. 

Regardless of the title and the alternative suggested, this is a fine example of shooting machinery. Love the uniformity and repreat and the DOF is rather excellent.
