I have a pic Im working on using the main camera. I want to keep the main fig. in focus and blur behind it, now here's where I have trouble I go into firefly and click on depth of field I then go into the camera properties to adjust the depth of field wheel but there is nothing to adjust the depth of field, everything else is there. I checked the Poser 6 book and it says there that there is a depth of field adjustment wheel but I don't see it. So what the heck em I doing wrong?
