Last night I printed a cityscape that I had shot on Rollei 400 IR film with a 150mm lens and Cokin IR filter on a Toyo 45AX. The image itself is not a 'winner' IMO for several reasons which I'll not go into here. Nevertheless I came away very impressed with this film.
The grain was so small that I had real difficulty focusing on it and instead used an object in the scene. For a 400 speed film, this suprised me. The print itself has excellent tonal ranges from whites to the blacks and absolutely beautiful mid values and is soo sharp that reflexively you reach for a magnifying glass to read the signs and look into the windows of the houses. And if that wasn't enough it gave this image a 1950's 'film noir' look. Posted below is a low resolution scan of the print on an Epson 3200 by an inexperienced operator (me) but it pales in comparison to the print itself. I wish you could see it.
This is truly a great film!
