Okay so I read the piddley paragraph on page 306 of the manual that talks about Depth of Field. Well it wasn't enough as I need help on how to use it. The manual states that you can change the focal length by inputting a numerical value or by selecting objects in your scene. Where do I input this numerical value and what does selecting by object do with rendering Depth of Field. How would I choose between sharp focus foreground and blurred background and vise versa? Thanks for any replies.
