Sauvie Island is located in the Columbia river near Portland, Oregon. It is mostly agricultural but is surrounded by natural areas that are set aside for migrating birds. The Grotto is a National Catholic shrine with a nice botanical garden in Portland. Both places are great spots to show off the effects of infrared in color photography.
I've been "saving" a few rolls of Kodak EIR infrared film. I'm not sure why except that it's no longer in production, and I don't want to say goodbye to it. If only Kodak Alaris could be convinced to bring back their infrared films. I've only got a couple of rolls left in my stash!
When conditions are right EIR produces spectacular vibrant "false" colors with good tonal separation among the various kinds of foliage. And spring/summer, when the earth is alive with new growth, is definitely the right time for this film. Instead of the usual red, green and blue sensitivity of normal color films, infrared color film has red, green and infrared sensitivities. In order to achieve the false color effect the camera lens must have a minus blue filter placed on the lens. Without it, the infrared effect will be overpowered by the visible blue light. This filter also modifies the resulting color transmission in the red and green layers of the film and contributes to the false rendering of color. I've found that a #15 tiffen deep yellow filter produces results that are most pleasing to me, but different degrees of infrared can be recorded using a variety of yellow to orange filters. I hope you agree that even though these images are a little strange, they are also quite beautiful. And whose to say that this is not God's view of the world.
