Scott,

Let me piggy-back on the preceding reference to the Ansel Adams exhibit in San Franciso since I happened to have seen last week the exhibit at the George Eastman House in Rochester, NY "In Praise of Nature. Ansel Adams and Photographs of the American West" (running until Sept. 16, incidentally). Ansel's signature was exceedingly small (as well as faint), hardly visible except at close range. So, on my 8x10's mounted on 14x17", my reveal is 3/8" on top and sides but a full 1/2" at the bottom to allow room for writing (corresponding to Ansel's own recommendation for prints 16x20 and larger, Print, p. 156). But the ultimate test, as with a photograph, is what it looks like when you hang it on a wall. Best, Nick.
