The Harris Shutter Effect

   Robert Harris of Kodak invented “The Harris Shutter” for making color photographs with the different primary color layers exposed in separate time intervals in succession. Now a days the term Harris shutter is also applied to the technique or effect.  While working on my Shoe Love project I decided to use it for the first time :

"In the Journey of Life, many Shoes are worn and torn."
“In the Journey of Life, many Shoes are worn and torn.”

    To achieve this effect you need to take three different photographs of a moving subject.  Using a tripod helps big time. The one above was shot with help of one, while the second one was shot handheld in burst mode, and required a slight amount of cropping and alignment. The interval between the shots solely depends on your subject.

    Once you have the photographs open them up on your favourite photo-editing software, in my case I use Adobe Photoshop CS6. Create a new blank file with the same dimensions as your photographs. Work with the channels tab instead of layers. Select the red channel from the first photograph, select the picture (Ctrl + A) and copy it, next go to to the new file, select the red channel and paste it. Similarly copy the green channel from the second photograph and the blue channel from the third photograph and add them to the green and blue channel of the new file respectively. Then switch to the RGB channel on the new file for the composite shot.

    In the result the non-moving parts of the photograph will look normal while the moving objects will appear in rainbow colors.
