While I was at the FPP Findlay Walking Workshop in mid-April, there was some talk about some film on ebay. It turns out that a seller had lots of 100 ft rolls of Kodak Hawkeye Traffic Surveillance Film - a 400 ISO C-41 color emulsion. There was a "buy it now" for less than $30, so I bit. I am amazed at the oddball films that show up on ebay, and have to wonder how many "custom" films were sold for specialized uses.
Anyhow, there is some literature on this film, and some folks on Flickr claim they have pushed it to ISO 1600 with good, if not grainy results. I myself wonder if it isn't just a variant of Portra 400. As promised, here are some images straight from the scans from Huron Camera without any adjustment on my part.
I think that the color rendition is good, and look forward to shooting more of it. I have a C-41 kit that I have yet to try, so perhaps this will be a good opportunity to see what develops :). The film seems a bit grainy, but that may be due to the scans on the Fuji lab equipment. I'll try scanning on my Minolta scanner and see if there is any difference. In any case, it is an inexpensive roll of bulk film that will be put to use.
