What was the subject? Outdoors in the bright sun? Did you make the paper
or purchase it. After 53 hours you should have gotten something more than
just "Evidence of a light leak". As for your use of a regular light,
remember that BP required UV light.

I am curious as to why you choose BP paper for stereo. I would think you
would want something that gives you a better quality. 

Provide more info.
