I agree that though there might be some problems with the "foggy condition", this shot is not sharp because of motion. If you look close at the pict, there is not one thing in correct focus. I also feel that some of the lights and the flag pole running through the foreground are a bit distracting. I am currently in a mentor program. We set and critique A LOT of photos, both good and bad, and he tries to have me figure out what kinds of things that could have been done to make them better. Distractions (lack of a good composure) are things that come up a lot. Just my thoughts, for what they're worth. I NEVER mean to offend. BTW, when did you take that shot?
I was in DC all week last week (3/19-3/24). A group of 30 adults took 31 8th graders on a field trip from Tuttle, OK to there. It was an AWESOME trip. I want to go back with the teacher by herself. She is the only one that can keep up with me. lol. Soooooo much to see.

Yep, that's it alright. I'm not too good with the technical stuff but I've learned from others that my settings were off.

Thanks for your post.

The image has motion blur. If you were using a tripod, this is called "coffee nerves." Many tripods cannot handle longer exposures, below 1/60th, like 1/2 second. Even IF you do everything right, the tripod is jiggled in a subtle way, from people walking nearby, hands on the camera, the camera shutter itself, the breeze or wind, and so forth. I own a Manfrotto, for example, where the legs alone cost $300. Another $150-$200 for a ball head, and this is a bright day tripod only. It has awful coffee nerves and cannot be used for longer exposures, and even when using mirror lockup and self timer, standing 8 feet away, motionless as the shutter fires is far from the best tripod choice for night shoots.

When you, usually after wasting many hundreds of dollars, find a tripod with all good habits, it's bliss. My ancient and heavy Gitzo Tele Studex Giant, no longer made, is one such tripod. You'd need an Abrams Tank bumping into it to create anything resembling coffee nerves, and though not recommended, you can do pull-ups on it. I have place half million dollar movie cameras on it, ten feet in the air. This is a BIG tripod. My custom made, gorgeously massive jib (which could easily tip a car, strength wise) is custom made to use this Gitzo.
