So who the hell am I? And am I qualified to do this?

I've worked full-time as a professional photographer since the early 1980's. I've worked primarily as a magazine photojournalist but have done portraits, travel photography and commercial photography working on assignment on five of the seven continents. My pictures have appeared in Time, Life, Newsweek, National Geographic and in many major magazines and books around the world. I've won many awards...yadda yadda. I'm not a scientist and these tests are not scientific. I've done some side-by-side comparisons but most of my remarks are observational.
