Ken,
Lovely interaction. It is fun watching these gentle giants. Did you apply any noise reduction? The blue colour of the water looks nice. Was it photographed from a boat? Thanks for sharing.
Ken,
Do you have NR on in your camera? If so, then DPP does a slightly better job than the lightroom. I may be a minority on this, however, I didn't like the incamera NR option. When I viewed the files at 100%, I found the details are messed up, with the incamera NR on.
I am glad you asked that question, I thought that I had religously followed the settings recommended in Artie's MkIV guide but I had not. I have now disabled this function (CFN II-2).
