Many thanks for the response. Actually, the first shot would be just the full moon and the second shot will perhaps have actors in it. You mention about metering, what type of meter is mostly use in this case? I have also seen some film that, I think, have a fake moon with fake skies...meaning they animate it and not the real thing. Would this method worth considering? If it is, any tuturials on how this is accomplish?
Again, thank you so much!
