Optional 2nd question: Is it appropriate for a non expert to ask questions of the experts in this forum or is this forum intended only for discussions among experts?

When this new forum was announced, DPReview described it like this:

"The second new forum is Photographic Science and Technology: a home for those wishing to discuss advanced technical matters related to imaging science outside the brand-specific forums. It's also intended to be the place for less technically-minded readers to pose questions of our community's smartest eggheads." http://www.dpreview.com/news/2013/10/01/site-update-two-new-forums

Thank you for the ultimate answer.
