Speaking of cyanotypes in Texas, my neighbor John Dugdale has a show on
now in Houston, is it Center for Creative Photography? Something like
that, but I've got the city right, and the 95 degrees outdoors right.
One room for the blue and one for the brown (tannic acid toned) prints -- so
get on your horse & ride over.... (Tho he said he didn't see any cowboys,
just very sophisticated art & photography-ites on his trip out for the
opening.)
