I apologize to have interrupted this discussion about an university level image with my toddler skills.
You are confusing a "university level" image, which this snap (in common with the vast majority of photographs posted here) plainly isn't, with "university level" critique and discussion, which we, collectively, aim for and often (well, sometimes) manage to achieve.
My point is no matter if it's natural or not or not caused by over sharpening...it is distracting in this image...which is what a critique is all about.
That is a perfectly fair point. Perhaps the thread demonstrates the dangers of leaping from observation of result to conclusion of cause.
The appearance of the water in the photograph accurately reflects (no pun intended) the appearance of the water as I remember it. I can see what people are getting at, but it's due to the weather conditions at the time the shot was taken, the sun reflected in the fine ripples around the beast. The effect may, as Slobodan suggested, be due to downsizing a very high-resolution image; certainly, it seems marginally more pronounced as posted here than it does in the original. I'll investigate.
