Here is one more Guadalupe River abstract.  I set the camera for a long exposure and then tilted it slowly upward for about 5 seconds.  If you get lucky, this can stretch the tree trunks up into the foliage and blur the two.  If you are not lucky, it looks horrible.  I did about 10 of these, and this was my favorite.  Most of the others were indeed horrible.
