Subject: [Leica] more Epson R-D1 IR images

As promised I did some more experimenting with the R-D1 and a R72 (89B) 
filter.

I have posted seven images all shot at ISO 200 or 400 (to be compared with 
other shot at ISO 1600).

The noise, as expected, is generally lower but there appears to be 
horizontal banding in areas of constant gray density (i.e., skies). This 
seems to be more pronounced at ISO 200 then at ISO 400 but either way is not 
good. 

I used Photoshop to minimize this banding as best I could but it's not 
always easy to do.

Next, I will do a series at ISO 800 (always +1 1/3 IE) to see what kind of 
results I get.

Your comment on the images and/or the technique are encouraged.

Dave.
