Mel Snyder: This is an example of where a -0.3 exposure compensation - perhaps even -0.7 or even -1 would be better. It would have saturated the colors better, more accurately reproducing what our eyes see.
let me first thank you again for your positive comments. They are pleasantly different from the often expressed negative comments which do not help.
Prompted by your comment about exposure compensation I've successfully started to engage Sony's Image Data Converter (IDC). The incorporated "Tone curve" tool enabled me to apply about -1EV to the above pic with the satisfying result of clearly more saturated colours.
After becoming acquainted with the IDC I of course didn't edit this image only but started to redo many other images taken before. Very rewarding.
Bottom line: I'm very grateful to you for having motivated me to do some "post processing", even without using RAW files.
As to your comments regarding high noon illumination: these images have been taken on bicycle or walking tours where the hours of the day were given.
