http://www.mindbites.com/lesson/1977-photography-light-color-psychology-control This lesson has a heavy emphasis on controlling light and color. Working with the sun and the different types of light that nature provides gives a solid foundation for the rest of this lesson. Studio applications of artificial lighting are covered along with the different types of light sources available to a photographer. The lesson concludes with a discussion on the psychology of color. Using color to help evoke emotions desired in a particular shoot a photographer can create a specific psychological response. Fast paced and packed with information, this subject is a must for any photographer who is serious about understanding and using the principals of good photographic design. This lesson is excerpted from the DVD, Learn Photographic Design, which is an excellent resource for those looking to learn how to take great photos. This is a segment cut from the DVD and includes chapters 10 and 11 (covering Controlling Light & Color and Psychology of Color).
