### 9. Angle of Incidence and Reflection

How can you control reflections in your image? What’s the best way to get rid of glare on glasses or other reflective surfaces? The answer lies in understanding the way light is reflected. Mark explains the angle of incidence and reflection using a laser pointer, a mirror, and some groovy sunglasses.

Angle of Incidence and Reflection

one of the fun things about light is the way that it bounces off of things. And it's a very predictable thing that we can show and use. And it's a principle called the angle of incidence and the angle of reflection. And so I've created some charts and graphs here. Let me show them to you. So when we talk about the angle of incidence and the angle of reflection, if you look at this, the blue line here, that's the incident ray, that's the light coming from your light source, the sun, your flash, whatever the heck it is and the light, if it comes in at a 36 degree angle and it hits a flat surface, something like a mirror or something that's very shiny piece of glass, it will reflect at exactly the same angle where it came in on. So if it comes in at 36 degrees, it's coming out at degrees. If it comes in at 50 degrees it's coming out at 50 degrees. And so we're going to show you a few things about this and how it works now. This is really important. If you're shooting things that are high...

Wow, Impressive with lots of information on light modifiers. Lots of variations of use and the bonus material. Mark is very good as a teacher. Glad I purchased the subscription plan so I can see the other Mark Wallace classes. Now to go to work and use the information.

I've heard much of this before, but this class really does a good job explaining and demonstrating the principles and techniques it covers. Mark is certainly quite knowledgeable, and he makes the material accessible and easy to grasp. It does cover quite a lot of ground, and while others may go into more detail, I think this class is great for building a good foundation.
