Wonderfully informative workshop. Thanks so much I have really enjoyed following this and I am printing it out for reference. Okay, one silly question. I think everyone has seen those little white orbs on their photos at one time or another. I have actually had people email me telling me that they are ghosts or spirits. Well, okay, I am openminded. But if you have a more scientic explaination for those little spots I'd love to hear it. Thanks again.
