DOUBLE EXPOSURE
Double exposure is a photography technique of combining two or numerous separate exposures into one. This technique has its implementations in fine art photography as well as highly advanced commercial photography. Evan, in the video above demonstrates really well how double exposures can be used to shoot fun and creative images. While the technique is ancient, only recently digital cameras re-introduced the function of shooting multiple exposures.
UNDERSTANDING DOUBLE EXPOSURE
To get better control of multiple exposure one should have an understanding of negative and positive values.
White in photography represents burned out data. Once you burn part of your image to the max that part is gone forever. You will not be able to bring it back nor overlay anything over (naturally) .
Black represents the exposure not taking place at all. Which is perfect for overlaying the second exposure. Black parts of the image are still virgin (unexposed) and the second exposure will fill those parts with substance. Obviously black and white are on the separate ends and there are all other values and colors in between.
Beautiful work!
Thanks a lot!
