Yes, I noticed in the manpage that "normtiff -h" is a subset of "pcond
-h".  In my case here, it worked well because these are nighttime exterior
images but made with crude representations for the luminaires, and pcond's
veiling glare treatment was not desirable for the purposes of these images
(and for some reason switching that off (pcond -h -v-) gave me some odd
artifacts).  It was about then that your email about normtiff showed up.

Thanks for the heads up though.  There should be a warning on the download
page for Radiance: "warning, entering DEEP water..." (or deep
*something*.)
