Beautifully composed photograph and also very good control of light.
This is interesting photo also because it raises few interesting questions.
1. It does not disturb me a bit but I have noticed that many people don´t like waterfall shots with long exposures so that water as if freezes and looses it´s natural sense of movement. There are two oints of view here: aesthetically that kind of "frozen water" is quite beautiful but natural loooking it ain´t.
2. I see you have chosen to shoot this landscape on a sunny day. You have controlled the highlights and shadows masterfully, but I suppose colours would most likely look better (richer, deeper and with more fine nuances) on a slightly overcast or lightly cloudy day or even during rain. But of course one usually can´t choose the weather;)
3. I see you have used f22 which hardly nobody uses when shooting with 4/3 format cameras due to diffraction problems that generally start to be noticeable from f14-f16 according to many tests. Ideal sharpness is usually achieved somewhere with f5-f11. To me this small web version looks sharp enough and you probably used the smallest aperture rather to get a certain look of flowing water than achieve the greatest possible depth of field?
Nice place. I´d like to visit that myself too.
Regards, pekka.

Lovely picture - I feel quite inspired.
With respect to Pekka's first comment, I find that 1/20 to 1/10 works well on water, but this picture has little overall movement, which I think is why it works so well on 30S. I would like to see it taken at 1/10 for comparison. It think it would appear more dynamic than 'fairy grotto' ish. I'm sure there should be a Unicorn in the picture. - Mike

I did take it at the speeds you suggested. The lighting on the scene allowed my to experiment both ways. The longer exposure which required filters actually was the sharper of the set.
