Hey everyone! Long time reader, first-time poster.
Recently, in a number of films I've been watching, I've seen a vast amount of ways to light through windows. I brought this subject up to a lighting professor of mine and we've been having discussions on it since. I know that to create realistic and natural window lighting, you need to use a mixture of hard and soft light to represent the sunlight and the soft skylight. Of course, the mixture and positioning of these depend on the time of day you're going for. I haven't had the time to do any tests of my own, but I will attempt some soon.
