By the way, when you sharpen your photo in Photoshop, do you use the Effects -> Sharpen effect which you can't really control or do you use something else?
I don't know what version of Photoshop you are using but in CS2 and PS7 you can go to Filter...Sharpen....Unsharp mask.
As a starting point use settings of 100__0.2 __0 Adjusting the 100 figure down to 50 will decrease the amount of sharpening. Increasing it in stages to a maximum of 500 will increase the amount of sharpening with each application.
Changing 0.2 to 0.3 will increase the pixel radius that is sharpened and give an apparent increase in sharpening effect. Be careful though as it can also cause the appearance of "haloes" around areas such as landing gear and edges of differing contrast.
Ctrl+F applies this level of sharpening each time you press it.
Before sharpening create a background layer. Apply sharpening until jaggies appear. At this point go back one step by pressing Ctrl+Z.
Flatten the image.
Create another background layer and sharpen one more time. This time select the eraser and rub out any jaggies that have appeared. This will reveal the previous non jagged part of the image.
If you see any small areas that require individual sharpening then use the lassoo tool to select them. With the selection active you can now apply what is known as selective sharpening by pressing Ctrl+F to sharpen the selected area only.
One tip when sharpening the whole image is to create a layer each time you sharpen and delete the sky once sharpened. This will avoid introducing grain which has a bad habit of appearing when sharpening the sky.
