It has been 37C here today, and at the end of a very dry summer our river is nearly dry. What pools are left are black, and full of reflections. Very difficult to photograph due to the bright sunlight on the white rocks contrasting with the shady areas, so a perfect place for some more HDR practice.
This shot was achieved in HDR Efex Pro from 3 shots taken with my compact camera, each 1.0EV apart.
