There are two non-IR images in the same album, to compare.  Which do  
you think works better?

The amount of exposure necessary really varies throughout the day.   
The A setting does a good job on exposure.  At times really high ISO  
is needed, but the noise ("grain") reminds me of the grain from Kodak  
High Speed Infrared.

A red filter doesn't seem to work well.

Some of the images (not these) are fuzzy.  I am pretty sure that it  
is not focus shift; perhaps it is a cousin to blooming that occurs in  
IR film.  Sharpening helps, as does slight underexposure.

I am using Adobe Camera Raw to open the DNG file.  I turn on the  
clipping warnings, and then adjust the Temperature and tint to  
minimize clipping.  Then I use Nik Color Efex Pro; BW Conversion  
Tonal Enhancer to convert to BW, and then do a final adjustment using  
Levels.  Bringing the middle slider up seems to make the image more  
dramatic.

Lots of fun research ahead.

Cheers,
Bob Rose

Experience should teach us to be most on our guard to protect liberty  
when the government's purposes are beneficent. Men born to freedom  
are naturally alert to repel invasion of their liberty by evil-minded  
rulers. The greatest dangers to liberty lurk in insidious  
encroachment by men of zeal, well-meaning but without understanding.
