guess the shutter speed

1 hour. ps: This is over my head.

More than one hour.

What's over your head?

pin hole cameras.... Clueless how long exposures get.

Typically, they can range from a second to hours. I think the longest pinhole exposure I've ever heard of was two years.

This one is definitely less than two years

If it helps, I had ISO 200 film in the camera.

Lets see, 2 year at ISO100 would be 1 year at ISO200. That's worse than watching paint dry.
So, a wild guess would be 8 hours (overnight).

Close enough! It was exposed for seven hours, and no, I didn't sit there the whole time

The camera is an ONDU 35mm pinhole (ONDU Pinhole Cameras - ONDU Pinhole Cameras - and no, I didn't pay 90 pounds. I got it when they were on Kickstarter.) F125, 25mm focal length. No viewfinder. The only lights were the lamp and the Christmas tree lights.

I actually started the exposure in the early evening - that's how early it gets dark in the winter - went about my business, and closed the shutter at midnight before bed. I didn't want to have to wake up just to close the shutter!

It's color film but I developed it as black and white because the film got torn in weird pieces and it had to be done by hand, but the lab I use for color always does it in the machine.

That's very cool! And impressive results considering it's simplicity. I'll have to find something now.

That's why I enjoy pinhole photography: the challenge of getting a good image with the most basic of tools.

Could end up being an interesting little game.
