I needed to check the light fall-off on my 285mm Wollaston Meniscus lens when used on an 8X10 camera.
I had no 8x10 film, so I shot a test photo on a paper negative.
Worked fine, told me what I wanted to know.

Then I thought...
Why don't folks talk much about paper negatives?
It's a great way to explore photography with minimum cost.
A quick search for "Paper Negatives on APUG yields only a smattering of posts buried in random "negative" hits.

How about a dedicated forum on this simple old process that goes almost unnoticed?

Here are three paper negatives (scanned and inverted, just for a quick test)...

The Fence gates were shot using my 285 Wollason on a dull Pacific Northwest day.
The bookshelf photos were done using my soon-to-be-anounced 335mm Wollaston Meniscus lens.
Both were shot using a beat-up 8x10 Kodak 2-D
On paper negatives, of course.
