As I was browsing stuff on the net, I came across this article in petapixel: http://www.petapixel.com/2011/03/14/surreal-double-exposure-photographs-created-entirely-in-camera/ It says that all the images were made using film and in-camera and without digital manipulation. How do you do these kinds of pictures? Is there a specific order, or maybe in the lighting used to get this effect? The main example that I am very curious about is this one: http://files.petapixel.com/assets/uploads/2011/03/de2.jpg . Care to share any tips? I have a Yashica D that is very easy to do multiple exposures so I really want to try this.
