Subject: [Leica] b&w infrared images from Epson R-D1 digital rangefinder

I thought I'd share the early results of an experiment capturing infrared 
black and white digitally.

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.
