This grapevine is quite old and is pretty gnarled. The canes need to be trimmed and it is in general disarray! Processed in Photoshop Elements 6 by changing to b/w, adjusting levels and dodging and burning. (I should be out working in the yard! :))
Camera settings: Canon EOS Rebel T1i, F/8, 1/100 sec., ISO 1250, focal length 100 mm. No flash.
