Choice can be a wonderful thing, even if the details of some choices can be troublesomely obscure. One need only look at Ultrafine Online's "Extreme 400" film in 35mm format to get a good example of this.
A private label film of uncertain origins, Ultrafine Extreme 400 is a film option available in 35mm format in both long and short rolls for a very reasonable price. I was generously bequeathed a small number of these 12 shot rolls by my buddy and fellow camera buff Mark who features his collection at The Gas House, and have really come to like this film.
Questions linger, most notably "who makes this film?" One might presume it is Ilford Private label film, which may make sense. As I seem to recall, a known Ilford product marketed as "Kentmere" has similar dot-matrix style film edge markings. Still, I've tried Kentmere 100 before and found it didn't have quite the contrast that I've noticed in the Ultrafine product.
Below is a test roll, shot on the Darth Vader camera, the Konica Aiborg, showing this film in action in various lighting.
In bright light, highlights can be hard to tame on the Ultrafine Extreme 400. However, in this case, the result is a very nice glow to this swan at Hagerstown City Park.
