I saw this killer '57 Chevy at the Ruby's car show in July of 2011. I made several sequences of it. This one was shot with the Lens Baby Composer using the Sweet 35 optic. This manual focus lens allows you to specify an area of sharp focus and everything moving away from that area becomes more and more blurred. It provides an interesting effect I like a lot. Given the reduced size of the focus sweet spot, I would guess this was shot at an aperture of about f2.8.
