Ed is correct that I was looking for technical not aesthetic input. Your eyes are better than mine - I had to look up "pixelation" and now think I see it in the flower but not the background, and still am not sure what is meant by (and can't see )"jpeg artefacts". Could you help me by pointing out these issues more directly?Here is another image taken about the same time but with less sun. I had not submitted this one because I thought the focus not so good. This is the unadjusted RAW saved as jpg with minimum compresion consistent with maximum file size for the site. Do the problems persist? is the light better?Actually, I find this rather bland but value your opinions nevertheless.Thanks for your input.
