Fuji Superia 400 - Single Roll Review - by Christian Schroeder
WebJun 8, 2024 · It's hard to overexpose Portra, so err on the side of a generous exposure. This is what I'd do personally, without wasting whole films on test exposures: Between 2 seconds and 10 seconds; give half a stop more, or 1.5 x the metered time. Between 10 seconds and 60 seconds; open up one stop or double the exposure. WebAs expected, the film's reciprocity characteristics follow a power law. The result was a correction factor of 1.36 (i.e. Corrected Exposure Time = Metered Exposure Time ^ 1.36), determined using a least-squares linear regression of log exposure time. Pancro 400 appears to have at least a stop of latitude in both directions, which makes Bergger ... nuget can\u0027t find package
