Sorry neglected to mention the renderer, they were rendered using SiTex AIR a plugin for rhino. The DOF is from the programme. Slows the rendering down though, so post pro maybe better. I like the renderer because its really flexible but it takes a bit of getting used to all the options available. So not easy to use like hypershot but able to do more.

I think there is a trial available although limited to 2 cores and watermarked.
