Tom Bowden Wrote:He is wrong on this picture but some of our pseudo photographic experts on the site should study his other photographic techniques in analyzing photographs. Long time ago, I was involved with a study to reduce X-rays to microfilm and retain 14 steps of the gray scale. This was in the 1964=65 timeframe. I was fortunate to spend time at Columbia University in their studies.
What's your point, Tom?
