JPEG quality used for posted samples....

I haven't read the entire thread. But, one thing that I noticed was how small the file sizes were in your posted samples.

For example, this one is only around 73KB for a 1000x667 pixel image, which tells me that a low quality/high compression JPEG setting was being used somewhere in your workflow (perhaps how you saved the image after downsizing for web posting).


So, part of what you may be seeing is JPEG compression artifacts from lower quality settings (higher JPEG compression) exaggerating any image defects.
