Ratings and Reviews


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.

Mark is simply AH-MAZING! If I was more of a photographer and not a videographer, I would definitely buy this class. I've learned so much about lighting which will help me with my YouTube Studio setup. He is obviously very knowledgeable. I am such a novice at photography I didn't even know what the light meter was used for. LOL. If you are a photographer you HAVE TO take this class.
