This is for 'Maris' from the above blog, if he should happen to wander by, open, and read this thread...
"So when someone has the original negative, that's treasure. The actual light from the actual subject came through a lens and nudged a few silver atoms on the negative. Ninety nine years later you can still see the mark that light left: The US Liberty Bell, a row of army barracks at Fort Douglas, a street car wreck in Ogden, farms in fields long gone but the mountains behind, still familiar."
This is the single most distinguishing definition of film-based photography. It's what makes it different from all other forms of image making. And it's what makes those photographs in the blog so special.
The negative bearing silent first generation witness to the events spontaneously recorded directly upon it. It had to have been there. There is no other undetectable way. That's where the goose bumps come from when one holds such a photographic negative up to the light a century later.
