the color was good but the black and white was eerily beautiful. I'm going to try that with the digital photoshop.
Well, I've got a confession here. Those weren't rangefinder shots (though I've got some RF shots of the same view that I've got to scan) but rather tests of one or another of the digital cameras I've got sitting around here. But they did fit the subject of the thread so well that I couldn't resist...
Quite a few digital cameras are fairly sensitive to the infrared range of the spectrum. (Some early ones are especially sensitive, as it was only later that manufacturers realized that IR could affect a picture's colors.) I have been experimenting with a cheap infrared filter I bought on eBay, putting it on the digital cameras and getting the eerie shots that IR gives -- near-white trees, near-black water, brilliant contrast between open sky and clouds. There are quite a few web pages dealing with infrared digital photography now -- just do a Google search on those words.
I doubt whether anything near the same effect could be gotten using Photoshop on a color picture, or by the use of colored filters with ordinary black and white film. A deep green filter (usually used to deepen skin tones in portraits) will lighten vegetation quite a bit, but it would probably reduce, not enhance, the contrast of clouds and sky. Of course, there are several infrared-sensitive black and white films available. They're used with an infrared filter, since the films are sensitive to the visible spectrum as well. The results resemble what an infrared-sensitive digital camera will yield, but of course the image is better.
You might want to give it a try!

P.S. Here's what a digital infrared picture looks like straight from the camera, before I grayscaled it in Photoshop. The camera "sees" the IR as magenta.
