Sonic Passages Published: August 3, 2010 in Bexar County Line, riverwalk by Kramer Wetzel. Sonic Passages Comments Brass is enhanced nicely by sepia. Yet I wonder which ‘sonic’ – sub or super is meant here… It’s an “aural landscape,” part of the new riverwalk – museum reach – extension. I like the tones of sepia here! Hi! Love all the colors and texture. Looks really good in sepia. Have a great day! Sherrie Food for Thought Comments are closed.
