Double Exposure in Lab

These pictures were made by exposing two negatives onto one print in the lab, using burning and dodging techniques.

This image was burned so that the image of the girl only showed up on the book. This print is slightly blurry because one of the negatives was out of focus.

These two images were the same negatives yet with different exposures of the picture of the peace sign. Again, I burned and dodged around the images to keep the contrast.

This image was done as if I were exposing each negative normally.

The larger image is out of focus and there is also a line where the burning/dodging wasn't done well...
