I'm using an unmodified Epson R-D1 digital rangefinder camera with a Hoya R72 filter (the equivalent of an 89B Wratten filter) over a few different lenses. The ISO setting of the camera was set to 1600 (the highest available) and images (exposed at f/5.6 or f/8) were underexposed. The R-D1 allows IE adjustments and I found that +1 usually produced usable images. +2 occasionally produced a better image. I have published five images here: http://www.leica-gallery.net/dlk/folder-8585.html All were handheld at 1/125 or 1/250 sec. All images were initially processed in Epson RAW and converted to TIFFs. Levels, brightness/contrast, and sharpness adjustments done in Photoshop. Most significantly the Noise Ninja plug-in was used to significantly reduce the noise that resulted from the high ISO settings. I have photographed many rolls of Kodak High Speed Infrared (HIE) and find the results pleasantly similar. The middle image of the five looks almost the same as the HIE image that I made last year. Next I will use some faster lenses (the five images presented were taken with either the Voigtlander 12mm f/5.6 or Leica Tri-Elmar f/4) so I can drop the ISO to hopefully 400 to see how the images look with much less noise. Any questions and/or comments are welcomed. Dave. -- David Keenan, ausdlk@swbell.net on 3/26/2006
