Hi & welcome Donald. I took a look at the image in your gallery, and I think the problems you're describing are just down to over-compressing the image. It's 1440x960, that's about 1.4 million pixels, but only 103kbytes in size. It's had the detail compressed out of it. To be honest, I think the quality is good considering how small the file is.

Looking at the picture in question, I agree that it's been compressed to the point that it's seriously degraded. I have to believe this didn't happen in the camera, but rather outside during preparation for posting.

I agree with those who feel this is not just a resized JPEG straight out of the camera. Not that I wish to doubt you, but the information contained in the EXIF data suggests this image was processed in an external editor.
For example it appears that the ProPhotoRGB color space was applied somewhere along the way. That alone would be problematic for an 8-bit highly compressed file. That without question would cause posterization with fine gradient areas. Also ProPhotoRGB is not an in camera choice.
But there are other troubling things that would cause issues. You seem to have a -3 2/3rds EC dialed in. It also suggests you used flash, but I don't know if it was the built-in or external flash. But never the less, with the exposure settings you have unless the ambient light was sufficient, I don't believe there would be enough flash power outputed to properly expose the full scene. That suggests that you might have needed to boost the levels in PP which would seem to increase the visible noise.
I'll take you for your word that you did no external editing, but the information in the EXIF data seems to contradict you.

I owe everyone an apology, still unclear about editing in Adobe rgb or srbg, also about resizing, the first photo was post processed and resized, and put back in the same folder agin sorry about the confusion. I'll keep trying, comments on the second post are welcome. I have reposted in my gallery new at posting also so forgive my ignorance.
