No, not a typo, back in the 80’s Kodak released Ektar film the first time around. I always thought it strange that it was from either extreme of speed. It was available in either 25 asa or 1000 asa.
I can’t say that I took much interest back then, I don’t recall ever using the 25, but I did try a roll of the 1000. I remember at the time thinking that it was better than the Vericolor VR1000 that was very grainy!
The above shot was taken looking down Shaftesbury Ave, in London, Theatreland! At the time I had a Cosina CT1 with a 35-70mm lens. Nothing special but it did the job. It did open up the possibility of night photography without flash or long exposures.
The above is from the same roll of film a few days later! Filming in Brussels, at the time Kodak had also just introduced it’s new EXR 16mm film! Burnt into my memory is 7245 50asa daylight, 1989!
