Composition and Cameras - Photographic Rendering with V-Ray for SketchUp - page 274

our renders will not turn out as well composed as we had perhaps hoped or even
expected.
For instance, the following two renders were both taken from the POV camera
view in our DT_Interior_Composition_Start.skp start scene. Clearly though,
each scene has been rendered using very different aspect ratio settings in V-Ray.
The one on the left was completed using the current 1.333:1 (or 4:3) ratio and a pixel
resolution of 1000 x 750, while the one on the right uses a 1.77:1 (or 16:9) ratio and
a pixel resolution of 1000 x 562. The difference this automatically makes to both the
composition and staging of the images is strikingly obvious.
The 1.77 (or 16:9) version feels more balanced and focused on the scene content
because it matches the SketchUp scene view that it was set up with much more
closely. Whereas, the 1.33 (or 4:3) version feels a little bit unfocused and unfinished
compositionally speaking.
Choosing our ratio
Obviously, the question of which ratio to use as we move forward with a project will
depend upon a number of factors, not least of which is the medium on which our
final renders will be used. For the purpose of our composition exercises here, let's
assume that our client has indicated that they want to place these renders inside an
HD Blu-ray presentation they are putting together. This means of course that we will
need to stick with the current HD aspect ratio setting of 1.777:1.
