The Holga doesn't have a B-stop, but if you are willing to modify your Holga so that it can't take
regular photographs, you can convert it to an old fashioned lens cap shutter camera. You freeze the
camera shutter open, and then use the lens cap as shutter.
Open the camera back. Remove 2 screws
Separate the shutter and lens from the camera body.
Remove 2 springs
Set the aperture to Cloudy. Hold the shutter open, glue in two places.
Glue the shutter button in place, reassemble the camera
