Another portrait.
This was one of those times that I decided to stress the CPU with a special effect. The depth of field here is not postwork but actual render. It required a pixel sampling of 16, and even then it's a little spotty in places. I'd have preferred to use an even higher setting, but I also wanted to work on other projects. Total rendering time was on the order of 36 hours.
BTW, the grass is mostly just hair on a cloth plane.
