Jetty Jacks

This string of jetty jacks, positioned along the brush-covered east bank of the Mojave riverbed beside the Rocksprings trestle, helps to control erosion of the embankment where the rails leave the trestle and head across land; a matching set of jacks occupies the same position on the western shore. Each individual jack consists of three lengths of steel angle joined at their midpoints, producing a structure like a six-pronged jack from the child's game; the lengths of angle are held in place by wire, laced like a spider's web about the jack's center. The jacks are then attached along a cable anchored at each end, the whole length—in this case, half a dozen or so jacks—protecting the shoreline by catching sediment and debris, as the river, flush with water when the winter rains are heavy, courses beneath the trestle.

 

Camera: Univex Iris (1938, with Vitar 50mm f/7.9 lens). The Iris is an Art-Deco styled, cast-metal camera with adjustable aperture, fixed shutter speed, and fixed focus. Its native film is Universal No. 00, a proprietary film manufactured for the camera's maker, Universal Camera Corp., by Gevaert in Belgium. 00 film featured six 28 x 38 images per roll, and at 32mm wide was just slightly narrower than 35mm film. Universal filed for bankruptcy in 1952 and closed its doors in 1964, so there has been no new 00 film for the Iris and other early Universal cameras for several decades.

 

Film: I have read of people cutting down 120 film to make 00 film, but because 32mm is an odd width, one would have to develop it in open trays and make a special film holder for scanning. I decided instead to use the next smaller film size, 16mm or 110 film. I made 00 backing paper by cutting down 120 film backing paper. 00 film's image length is nearly the same as that of 828 film (00's image is 38mm long, 828's is 40mm), so I used my 828 backing paper template (www.pheugo.com/cameras/index.php?page=spool828), cutting it slightly narrower for the 00 spool (32mm rather than 828's 35mm), and reducing the length from 828 film's eight image length to 00's six. When cutting down 120 film for 127 film cameras, there is a strip of film about 15mm wide left over; I used one of these strips to roll up in the backing paper. I used my accustomed 100 ISO Arista.edu Ultra film, developed in Arista Liquid Developer for 8:15 minutes @ 65 degrees, and scanned with an Epson V600 scanner. This was my first time developing and scanning 110 film—thanks to my Flickr friend Nyms for her insight on the Yankee Clipper developing tank!
