Per request ... It's interesting that if you post a photo and suggest that a certain area be concentrated a lot of detail becomes exposed. These photos could be of interest in several different ways, but by suggesting to focus on the canopies you may see what I'm thinking. Sources are all over the place on the internet and a bunch of my stuff.
