I'm creating some studio-shot style images of products. I'm trying to get the foreground elements in focus while having the background blur slightly.
I've done a lot of real world studio photography and I know that depth of focus and depth of field are two different parameters (though frequently confused). Put simply, depth of field references the precise centre of the plane of focus as parallel to the image plane, while depth of focus reference the sum of the distance on either side of this plane that remains in focus.
But 2.6x only seems to offer control of the depth of field, so that only that exact plane is in focus, and everything either side gradually defocusses. Or am I missing something?
The point is, I want to know if there is a way to control the z-depth of the area in focus, not just it's distance from the camera.
