The southern end of the High-Level Bridge in Edmonton. I snapped this slide with an old 35mm rangefinder in 1970 using Ektachrome film. In some ways, time exposures with film were easier than digital shots. Modern digital cameras are far more sensitive than old color slide films. You wouldn’t need a very long exposure at high ISO to record this scene digitally. In the 1970s Ektachrome was usually ASA 64 or 100. To get this shot I braced the camera on the bridge road railing and held the shutter open. I can’t remember how long the exposure was but it was probably ten to twenty seconds. Film suffered from reciprocity failure which basically means the effective ASA decreases, nonlinearly, with exposure time. At some point, the failure point, the film’s ASA is essentially zero. What I like about this shot is the distorted color. When scanning and adjusting this slide I retained the unbalanced color. Daylight films used at night often produced lovely hard to emulate colors.
