In 1973 I built an UW housing (parts from Mart Toggweiler if anyone remember him?) for my grandfather's Argus C3 he had given me and another one for his old Bell & Howell 8mm movie camera. Built a darkroom in my dad's garage and had all sorts of fun... A few years later I got an Ikelite housing for a Pentax KX... Might have to get back into UW B&W film photography...
Beautiful photos Mark. You have a great talent.
Back in 1979/1980 I built a housing for an old Bolex 16mm movie camera using Mart Toggweiler's book as a guide. I used the camera for documenting the Cordell Bank Expeditions off San Francisco. I took it down to 200 feet and it worked without a single leak. I still have the book in my library. You just don't see homebuilt camera housings anymore today due to the Gopro video splurge.
Here is my copy of Toggweiller's book.
