About the Image(s)

During a photography workshop in Alaska, I photographed this group of Steller sea lions resting on rocks near Homer from a boat. I made only minimal, basic adjustments because I may enter this image in the Nature category.

My camera settings were f/5.6, ISO 100, and a shutter speed of 1/800 second. Could you suggests ways ro reduce the distracing bright areas on the rocks while staying within the PSA Nature editing rules?
