- production photos are USELESS FOR THIS
I disagree. While production photos are rarely indicative of what the actual scene looked like in the film, and you should not be trying to MATCH production photos by any means, what they are great for is giving you a sense of the natural color of sets and costumes, which is very useful in trying to understand things like just how green Tarkin’s uniform should look under certain lighting. It’s not a source to be matched by any means, but they’re still useful as reference when all of the sources you are trying to match contradict each other in some way.
