It seems that I need to repeat myself, but any blotchyness is due to the small file size of 76K, due to compression. The colours blend very well in the original multimegabyte file, 300 pixels per inch at 14 inches by 9 inches.

You should also be aware that water is often shot at slow shutterspeeds in nature and scenic shots rendering it soft, as it is here. At 5:00 am in the morning, at 450mm at 5 seconds, you do not get sharp edges to the water. . On a boardwalk, over a swamp, with the light changing very quickly, moving the beach chairs is also just NOT an option either. They are too far away.

To repeat myself even further, noise can easily be processed out as well, so that is not a major problem either.

Although not perfect, this is an example of a common style, acceptable to many publishers. I will have no problem with publishing this photo.
