The correlation between data is open to interpretation. I clearly state that A15 is a small data set in a large file where film grain is an issue. The A20 is low res scan as I clearly show. Shadow angles differ as well.

As to experiance my work has been seen on movie screens, movie posters, vcr tape covers, video games, cd sleeves, vehicle graphics, large truck advertising, sighs, magezine adds, and things I cant remember. Have not made it into national geographic yet but I do read it, fabulous magazene. No longer working so nothing recent.
