A question I have always asked myself, knowing that a lot of the things from the Prequels that people think are CGI and are actually practical, was why Lucas and others working on the films failed to construct an outer environment that would make the practical sets look real? An example that all of us know would be the scene in Dex’s Diner. It looks very glossy and slick, and from a first, and maybe even a second glance, especially if you don’t know it was practical, it looks like the only non-CGI part of the scene was Ewan McGregor as Obi-Wan. Why is this? Personally, I think it is because of poor usage of blue screens on the exterior, which would apply to some of the other examples, such as the Naboo miniature, which was surrounded by blue screens and thus felt out of place. What do you think?
