After seeing the demonstration by Serios I wrote to Dr. Eisenbud --- in part:

. . . I believe the recognizable images, which are unrelated to the existing environment at the time, are produced by Mr. Serios by a combination of short focal length lenses and various kinds of transparencies, which he adroitly conceals in front of a Polaroid camera . . .

Dr. Eisenbud ask me to demonstrate to a "committee" of eight men, all doctors except two, my method of making photographs similar to those made by Serios. I was greeted with skepticism and criticism at the meeting and I realized quickly that debunking was not a popular field to enter. As we sat around a conference table, I did not take five to eight hours to obtain an image; I did not attempt sleight of hand and of course drank no alcoholic beverages.

I did show them how easy it is to make images similar to those produced by Serios.

However, to my surprise, I sat before a group of believers of the paranormal. (I could not fathom the naivete and gullibility of these professional men.)

A few days later Dr. Eisenbud sent me a copy of a three page letter he received from one of the members of his committee, the Chief Physicist and Engineer, Research and Engineering Department of a major Denver company. In part he said:

He (Nile Root) did produce interesting camera effects using his detectable gimmicks under conditions selected by himself. In my opinion he proved absolutely nothing.
