This is also my fave of the three. Really like the point of focus and how the red background complements the blue spindle. Are you using a new 150mm macro lens? :)
this definitely has to be my favourite of your three.
may be because of intriguing feeling i have about the dof. threads and needle both are in focus at center but only needle is in focus at its both ends. i would have expected threads along the horizontal line of needle-point to be in focus (both are in same plane) too. may be there is just enough more threads at the center to cross the dof plane. in any case, i like it though. -Abstract
