I appreciate the feedback. There is a lot to learn. It's harder to see where the room for improvement is when you're don't know what can be improved.
I shot it at F22 @ 1/13 second. I was using a monopod. I wonder if I was moving a little. I should probably back away from the F22. I was probably focusing on the bridge, but I can't remember for sure.
Dan, what is keystoning? I will go back within the month and post the new photo.
Thanks again.
Yeah, probably back off the F/22, to more like f/16, or even lower.
Sent a Full Frame (FF) camera, to a subject distance of 80 feet, and even at F/4 it will have acceptable focus from 40 fee to infinity. For FF cameras, and lenses, going tinier than f/16 probably brings in "diffraction", which causes softness.
For keystoning, vertical lines can be tilted either outward or inward, like they aren't "vertical". If you point the lens "up", even a few degrees, the tops of buildings will be less as wide as the bottom, so the lines "bow inward".
You can usually set a cameras LCD to show a "level" line (rotation), and some have a 3d level, to show you when the rotation and the up/down are the same line, thus all is straight and level. But for tall buildings, that is why they have tilt and/or tilt/shift lenses, and you don't want to go down that road yet.
