E04a The Shutter Notes
This episode was originally planned to cover both the shutter and the aperture but as the recording topped two hours, we decided to separate the two concepts. In two weeks we will continue as we focus on the aperture.
Right off the bat, Graham can’t remember the name of the camera repair guide he read. It’s Camera Maintenance & Repair by Thomas Thomosy.
Contributor to the forums on the Homemade Camera Podcast Flickr group, Flaver-D’s projection-TV-lensed experiment is discussed (12:10) and how having an adjustable aperture is not always very important. Nick brings up the concept that along with shutter speed and aperture, you can use neutral density filters to control exposure as well (12:35).
They discuss the Garbage Cam Build of listener jojonas on Flickr that uses a magnifying glass and black and white printing paper to get some very interesting effect (22:55). They also talk about how the movement of shutters can cause distortions in the image such as the famous forward-leaning race cars from the 1930s (38:25).
The boys try to tackle the concept of slit-scan photography such as that produced by James Guerin, maker of the Reality So Subtle pinhole cameras (41:15).
The Phochron XA shutter tester is mentioned at (58:00) and how it can help with determining the accuracy of settings of older shutters.
Nick reminds us that in the early days of photography the Guillotine was a handy way of creating a consistent shutter opening (1:13:00). Almost immediately afterward they talk about Flickr group member Jonas and his schematic for a shutter that employs magnets from headphones to actuate.
