4771Re: tc-list Recovering the Invisible? (Imaging techniques)
- Oct 7, 1998It might be worth point out that the Eastman Kodak company used to have a
series of professional "handbooks" on infrared photography and UV
photography. They were available at a nominal price (each was 30 pp. or
so), and were done with a commercial goal in view: to encourage the sale
of IR film and UV etc. filters.
Twenty-five years ago, when I wrote to the FBI about advanced photography
techniques for detecting faint MS writing, they directed me to Kodak...so
if it's good enough for them...
Digitizing (and chromatic and "angle" recording of images, which are then
"digitally" reassembled) have surpassed--to the best of my knowledge--the
traditional photographic techniques. Some of this has been done with parts
of the Dead Sea materials.
