Hmmm...To me, the horizon line looks slightly tilted to the left. Am I the only one? |
We aren't shooting seascapes here people. The horizon isn't going to perfect all the time when we have hills and mountains...

It's funny how different people use USM different ways. This is soooo far above what I use I wondered if it was a joke Brent. The radius will, of course, go up the larger the picture, but even on my 16x24, I can pretty safely say I probably didn't go higher than 2.5/150% (and possibly lower).
For our little 640px entries, I rarely go above 0.9/100% and often am down at 0.7/50% |
it was a joke, I tried to give outlandish settings in regards to everybody over sharpening everything... ;o)

A good overview of the principles and techniques for sharpening here:

Just applyig one USM setting to the entire image won't give optimal results. The software I mentioned in my previous post does all this 'hard work' for you and gets the very most out of an image without oversharpening it. |
If you have PS 7 this approach with "Lighten" and "Darken" layers is the way to go, especially if you don't have a third party sharpening tool. It works very well.
Russell Brown explains this same technique in this entertaining video:
Russell Brown's Advanced Sharpening Tutorial for PS7
CS2's "Smart Sharpen" does an even better job if you have that. Russell has a fun video tutorial for that at to:

OK, I can't be silent any longer. Being intimately acquainted with both the photographer and the site of this fantastic picture, I want to clarify the horizon question. This picture was taken looking roughly West to East across the Rio Grande River valley just North of Albuquerque, New Mexico. On the East, this area is bordered by the Sandia (watermelon) Mountains having an elevation of over 10,000 ft. The tilted "horizon line" is not the horizon at all but a shadow made by the sunrise coming over a low place in the mountan range. So please, no more comments about the "tilted" horizon.
Boy that felt good! |

First let me say I am in total awe... this is a fantastic picture and one of the BEST EVER entered in a DPC challenge! It deserves every accolade it gets.
But despite your familiarity with the area and how good you feel about it, you are in error about the image being level.
It has a noticeable counterclockwise tilt (left) of 1 to 2 degrees, I believe. Wellll... unless there is a strange wind blowing all the ballons leftward off horizonatal.
This is easy to verify with Photoshop.
You select the measure tool and "measure" from the tip top of a ballon to the middle bottom of the basket. Then you select Image->Rotate Image->Arbitrary. That displays, in degrees, the amount of rotation needed to make the ballon strait. If you check very many ballons you will see it will consistantly need somewhere between 1-3 degrees clockwise rotation to make them horizontal. None are tilted the other way.
justin_hewlett is correct.
