Digital BW, The Print

Maxmax.com also does these conversions.  I just received an IR  
dedicated Canon XT Rebel from maxmax.com that works very well.  An  
internal 715 nm filter replaces the IR cut filter so viewing and  
autofocus both function normally.  I just did some test shots outside  
at ISO 100 with exposure of 1/200 sec @ f/11.  Auto exposure works  
well if you first set an exposure compensation factor of about -1.2  
to -1.7 stops.  Sharp, clean images that process easily using camera  
raw in CS 2.  I'll post a link to some sample images, after I've had  
a chance to shoot something worthwhile.  I used to shoot a lot of  
digital infrared when I had an old Nikon 950 (see site below) so I'll  
probably revisit some of those scenes with the IR Rebel.
