I would like to introduce you to a beautiful infrared film, which is not manufactured anymore. The Konica Infrared 750 nm is a black and white infrared film, sensitized for a wavelength up to 820 nm to the infrared region.
The Konica 750 nm is not manufactured anymore. It has a light protective layer and provides relatively "normal", sharp images. The advantage of this film is that you can place it in daylight into the camera. You can use it as a 35 mm (producing 24 photos) and as a medium-format film.
I took the photos with the Lubitel 166+ and an R-72 infrared filter. It's also possible to use a red filter. In the datasheet, it's recommended to expose the film with a shutter speed of 1/60 and an aperture of f5,6. In addition, the IR effect is greater when the sun is behind you. I have also tried to observe my recordings and must say that I like the IR effect of this film. I also like that you can set the shutter speed and aperture only at the beginning and don't rethink about it before each exposure.
I wrote some notes about the IR-photos:
- Leaves, grass, moss, etc.: very pale, almost white (wood effect)
- Needle leaves: dark, almost black
- Water (quietly): dark, almost black
- Water (churned): white
- Blue skies: very dark to black
- Cloudy sky with blue components: white clouds, black sky, dramatic storm mood is typical for IR
As you can see from the list, the IR effect is greatest when you take photos of nature. Photos of people are possible. The clothing of my friend appears white on the photo; he had a pair of jeans and a green T-shirt on. The Konica Infrared 750 nm photos were developed as a black and white film. I developed it in Rodinal 1+25, 5 minutes (1+50, 6 minutes).
Conclusion: This film is a straight-forward black and white infrared film. It's easy to produce the IR-effects on the photos. With the right filter, this film is perfect for beginners in infrared photography because aperture and shutter speed does not need to be constantly re-adjusted. If you see this film, then buy it!
