Ultrafine Ortho Litho Film

 This film is orthochromatic, which means it is not sensitive to red light, this means that it can be handled under red safelight which is awesome. It is a Kodalith style of film, which was originally used to produce highlight masks for fine art printing. It is a quite unusual film, if you want to shoot the high contrast images like the on es below then it needs to be rated at 8 - 10 ISO, if you want to shoot more conventional tone negatives then rate it at 10 - 25 ISO. For this test, I shot at 10 ISO.

Even in tropical sun, it can be problematic shooting this low ISO, but not so much, you just have to shoot in good light, it's only just over 3 stops less than 100 ISO.

With film, development matters too. This roll was developed in HC110 dilution B , and it was developed for twelve minutes which was probably a little over developed. It is possible to use paper developer as well, and don't forget it is not sensitive to red light, great!

I think the bloom we see on the blacks may be because of over development.

This is really a cool film, but you do need to think carefully about what you shoot.

These shots were all the middle of the day, around EV 17.

To try this film in Cambodia, you will have to order through one of the ebay ordering services, it comes in rolls of 20 exposures for about 5USD.

Try it.
