Thanks for the insight on lens performance and small apetures, I understand realize what you are talking about now and maybe intuitively at the time because most of my other shots were at an apeture of F/22 or larger after this one and I changed my ISO back to 100. The rest of the shots just did not have the type of light that this one had.

The grain, (not sure if it is the lens or the camera)hindered my sharpening in photoshop. Using unsharp mask, when I would increase the amount past 150 or decrease the threashold below 5 or 6 I would get a snowstorm of white points all over the image, that is with a radious of .5.

I was really fighting with time, I saw three different stages of light while I was setting up.

twm122 - yeah I am getting in a few before the GTG, that is a very easy drive from natural bridge probably around 15 minutes or something

Wow, that is great. Are you getting in a few before the GTG in May?

Beautiful Scene, made even better by the comments! I had no idea it would make a difference to the sharpness.

Yep, I agree with Robert... my first thought was,"wow, that is a beautiful scene." & my second thought was,"too bad it isn't in focus (sharp)."

But, great photo, good colors, and nice shadows.

Congrats on a nice shot.
