Bear in mind that normtiff (and ximage -e auto) don't do everything
pcond can do. In particular, they cannot simulate human loss in acuity
and veiling glare, so if you really want "pcond -h", don't expect
"normtiff -h" to work as a substitute. Also, if you are converting
animation frames and want all the frames to use the same tone-mapping,
pcond -I works with the output of phisto, whereas there is no such
option in normtiff.
Just had to throw in some caveats.
