I don't recall this being brought up, and I do not know if Ady has already filmed the new canyon shot, but would it make sense to add a slight glow to the walls from the Millennium Falcon's blue boosters?
The only reason I ask is because I thought it actually was a cool effect to have in Attack of the Clones when Jango and Obi Wan were flying through that hole in the asteroid and their ships had lit up the area around them. Though it could be argued that since they were INSIDE an asteroid at that moment, that there would be complete darkness which helped the lighting be more visible, but the canyon in ESB is rather deep as well, so the same logic could apply. I was thinking since the shot is being recreated, perhaps it could enhance the new version a bit further.
Thoughts?
