I think most people who have never been to California have misconceptions about this state. We can spend hours talking about the politics and people here, and you probably won't get much of an argument from me. But let's talk about the weather.
California is a pretty big state and since it covers such a broad latitude, the weather varies quite a bit, depending on what part of the state you are in. Where I live, which is about in the center of the state, it is a large valley that is like a big bath tub. In the winter, we will get storms rolling in from the north and that brings some rain. Not a lot, as this is a pretty dry area still. Usually after even a light rain comes through, that is followed by a few days of fog. This time of year, we don't see a lot of sun. If it isn't foggy, then it is overcast.
High speed cameras work better with more light so even when it is overcast, it can be too dark to film in. This is frustrating because I usually have a lot of ideas to film but just can't do them. So I have to film indoors using my LED spotlights or wait for a rare sunny day.
