John "Chinatown" Alonzo was in charge of the cinematography.
I actually loved how he treated lighting realistically. The Veridian star is just outside the Enterprise's massive windows and so that's what casts long shadows, which Picard walks in and out of.
Somehow makes everything less like an overlit film studio set. Of course, you could probably make a case for a 24th Century lighting system, polarised windows etc which accounts for it. Maybe Generations takes place on what should be the night shift, with subdued lighting but Picard and co are all up, taking charge of the emergency.
