Kevin Strandberg is Professor and School of Art Director at Illinois Wesleyan University, Bloomington. Besides, he is an expert in camera making, an activity he's indulging in since his teens. For a good read on that, have a look at this Washington Times article. His website can be found here.
The two cameras in the forefront are two 6x12 cameras in vertical and horizontal format respectively. They were constructed using modified Cambo passport cameras and backs have much similarity to that of a Cambo Wide. One of the cameras is attached with a 65 Rodenstock Grandagon MC lens mounted on a matched focusing helicoid. The finder being salvaged from a broken Widepan camera.
The second camera has a 75 mm Mamiya Polaroid 600 SE lens with a Cambo Wide finder. The film backs are Horseman 4x5 to 120 types and the lens protection bumpers were sourced from Horseman SW lenses.
The other cameras in the background are 6x9 wide angles made of Graflex XL bodies attached to Mamiya and Schneider lenses. The farthest one in the picture is still under construction and based on a Polaroid MP3 copy camera. like one of the 6x12s, it too has a vertical format with a Mamiya Press 75 mm on it.
I thank Professor Kevin Strandberg a lot for providing the pics and details for these cameras. You can learn more about his cameras , the artworks they produced and a book authored by Kevin on these cameras from my earlier post.
