There is a book called, Light, Science & Magic, which is one of the fundamental books on Lighting for photography. Throughout the book, they have diagrams, projects and more, and encourage users to go through the examples and gain a full understanding of the concepts within the book. Before anyone thinks this is a book on studio lighting, you would be mistaken. This is a book on light, and how it reacts to surfaces, direction, and more. This is about light, period.
I wanted to gauge an interest from members of the group who may be interested in learning about light, going through the chapters, and doing the projects within to help gain a better understanding of the processes, and learn how to work with all types of light and surfaces.
There is a new edition (4th) that we would be using in the group if this is something that we would like to do.
