The next adjustment that we want to make is to direct the viewers' attention inside the image a little. We did make a reasonable start at this by paying attention to camera placement and lens choices in Chapter 8, Composition and Cameras, but with an overview type wide shot in a fixed environment such as the one we are working with here, there really is only so much that we can do using composition.

So, a real-world photographer would probably further direct the viewers' attention here by introducing a little bit of depth of field to the shot, pushing the viewers' eye into the room and towards the exhibits on display there. Again, this is something that could most certainly have been handled inside V-Ray using the physical camera controls.

However, adding genuine 3D DOF to a render becomes very expensive time-wise, and of course, once it has been baked into the image, you are stuck with whatever settings you applied; there can be no tweaks or adjustments...
