Dartmouth Study of Backyard Photo supposedly confirms authenticity

[Tom Bowden]

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?

My point is I understand the loss of grey steps in any reproductive process between silver film generations. I have not bothered to learn the processes for enhancing in this digital age but if the digitized film was not the original then contrast and grey retention is dependent on many variables. If you do not know the intermediate steps then how can you reliably judge the final product. I have seen enough discussion on this site to understand when someone is blowing smoke. I am not into name calling but over the years I have seen enough to know when someone is reading more into a photo than was there. Badge man and prayer man are perfect examples. Another was the Cooper use of the Z film copies.
