DOF...

I have tried on several occasions to use depth of field. Can some one please explain how to set up the focal distance... I have turned the camera on and created a line from the camera to the object and used the read out on the distance but this does not seem to work so well when the camera is angled.

Are you using the post effect DOF, or the real one from the view dock bar?

if u want a custom range where the camera isnt directly facing the object you want to focus on, you need to make sure "use view target" is unchecked. you have to play with the focus distance until you reach a distance (from camera i am assuming) that the focus area is. the f-stop just increases the ammount of blur of things in front and things behind the focus range. so if u really want to see what effect your chosen distance is having, set the fstop lower to increase the blur ammount, though render time will most likely be affected.

Hi Liam,

My method for setting up DOF is to turn on the camera in the Perspective view (F6) and use Osnaps to measure (Distance) from the point at the back of the camera to the current target point on the camera or to a point on the model. The distance is reported in the command line. I then enter this value in the DOF settings instead of using the active view target. The default f-stop of 7 is rarely appropriate in my experience. I usually enter something between 12 and 18.
