Oh yes, and a super cool photo hack!

Nice, I have been hunting around some photography sites for this exact thing. We will see if its useful for what I need, good post.

That’s one impressive camera. Thanks for sharing.

Some of us old timers were doing this back in the early ’80′s.

If you want to see something really interesting, look up “Sabattier Effect” or “pseudo-solarization”.

When I was a kid I tried to make a photographic emulsion from a recipe in an old science book. The local drugstore pharmacist refused to sell me the required chemicals, insisting I was going to make explosive silver fulminate instead, and he proceded to show me his hand which was missing a few fingers…

Anyway, his refusal diverted me from a photography hobby and started me on a fascinating new educational persuit, which culminated in serious bodily harm of my own in my senior year of high school.

The moral of the story? Be careful HOW you deny something (you may cause what you are trying to prevent)…

Perhaps obtaining silver chloride as used here is less of a problem than using the silver nitrate that was require in the photo emulsion recipe I was planning to use.
