Nice tones, picture has an old time look to it. Water movement looks good too, how long an exposure? May want to clean some of the dust spots off on the right side.
thanks everyone for your wonderful comments
john, the exposure time was: 1/4sec at f22.0, and thanks for pointing the dust specs out, i can't believe i did'nt notice them, but looking at other images taken on the same day they don't show up, i think perhaps they might be spray spots from the waterfall.
peter, thanks mate! and thank your wife from me, i'm so glad she likes it.
