The reason that you guys are here today is to learn some compositing techniques, the essential techniques. And composting can be complicated and maybe difficult if you don't understand what makes an image look realistic. When you're looking at an image sometimes technical aspects of a compost might be correct, like for example, masking, the shadows, things that you usually think about consciously might be correct. But there's something in your brain that tells you that something is just not working. You've probably had that before in the past where you have a subject and maybe it looks like they're sort of floating and you can't really tell why. And that's because when we composite we have to think about how our brain sees the real world. And that's what I'm gonna focus on mainly today, on those things we have to think about when we compost, those essential skills and techniques.
