OscilloPinoscope in 6 minutes

A friend gave me an old Oscilloscope which had a Polaroid back.    Unfortunately, the shutter was sticky.   Fortunately, the Polaroid back was easily removable.

I realized it would be super easy to make an instant film pinhole camera from it.    I knew all I needed was a pinhole, some cardboard and gaffer’s tape.   So I decided to time myself to see how long it took me to get it working.     It took about 6 minutes.   I had my first photo in 12 minutes, after a few exposure failures.

Using Pinhole Assist as usual, I just guessed that the pinhole was f/250  (I dont remember), and added the reciprocity compensation in the app for the Fuji FP-3000B.    Exposure time in the brightest room in the house, my bathroom  (forgive the mess) was about 30 seconds.

It doesn’t have a tripod mount, so I just propped it up using some glasses cases.

Scroll to the bottom to see the photos I shot.

Handy dark slide.

I could have just used gaffer tape, with no cardboard underneath.  There's no shutter.  Just the dark slide.

The "camera" was about one glasses case width away from the base of the typewriter.

I was about 4" away from the pinhole.
