Thanks for all your comments. Yes, I agree that this is a wierd one.
The template .tif version I've kept on my PC looks much better than the this example.
Obviously, the a.net compression is killing the shot too.
The uncompressed shot I uploaded @ 600k jpeg.
This was actually my second attempt with even "more" sharpening than before.
I have to agree too that the saturation is a bit high, now that you've pointed it out. My eyes can't seem to cope with it...and Chris's assertion of too much contrast? Maybe caused by my application of auto-balance (I think)...
I've taken quite a few sundown shots lately with variable results.
Now that I've got a handle on it, I might have one more go on the original.
If not, it's going into the bin....(do I look like a worried man?)
