The 101 freeway in Petaluma

Interesting! I wouldn't throw it out. Just say "I meant to do that"!

@bsdunek thanks! I didn’t throw it out, which is why it’s posted here.

This is a great example of Pinholing, I love it.
You got my vote.

Getting the film holder to seat properly is the challenge. You may be dislodging it slightly when pulling the dark slide.

It does convey the sense of the freeway speed.

@grahamp I didn’t have any felt or gasket material between the film holder camera body on this shot. I just added some sheet foam with felt to hopefully deal with it. I’ll do another test shot in the next day or two to see if it did the trick.

the great news is this is actually right outside my lab, so I can make the test shot and process it right away to see if it worked.
