I must admit to having a bias for waterfall pics. This one I like, for the most part, except the exposure could be a little shorter as has been noted. I would also like to see the colour version for comparison as not every image makes a good B&W image. This one has a lot of whites - the water, and a lot of blacks - mostly everything else. I always like to see some various shades of grey in my conversions. How did you do the conversion?
My other thought was that it would be nice, for comparison, to see an image when the falls is not so "roaring".
