As an exercise I downloaded the full-size JPEG Gary posted of the building and the traffic light. But it was already "JPEG'd" so there wasn't a lot I could do with it. Gary's comment was about sharpness, and at a 100% view (which is a minimum you'd use when sharpening) it's smeared; once you've lost detail you can't get it back.

Now I am going to have to take exception. No, nothing is "smeared" in that picture. It was taken on a tripod, SSS turned off, manually focused to perfection with double magnification, and fired with a 2 sec timer. I have already posted a sharp as a tack crop of the street lights with every little red LED visible at that great distance - about a block and a half - well, you can see how small they are in the original. Every brick is countable, every sign readable, a perfectly sharp image.

I hope my statement doesn't offend but ... well, shoot a JPEG and you GET a JPEG (just kidding!).

Don't even use your PP software, just look at the original view of the large one you posted; move toward the back of the building and also look at the sky.  I only saw this because I downloaded it and cropped it similarly to your traffic light clip - and then easily saw what was there. Since I haven't seen your RAW yet I can't tell if it was just the camera's JPEG, the lens or something else. Would this show up on most prints? No. But now you could perform a test against a well-converted and processed RAW to see if there's a difference. In a way, it's not that it wouldn't normally be noticed in a print; it just happens to be in the much-less-noticeable area it's in just because you did such a good job of taking it. In some ways the RAW vs. JPEG issue is about the lattitude you have when editing, but you could also get one of those "not quite perfect" JPEG shots where the issues are more easily noticed - and I think they'd be much less so in the RAW version.
