I just read a post where the poster suggested to the OP to stop sharpening the sky. Is this possible to not sharpen the sky and sharpen other areas of the image? Or was he just taking about images with a lot of sky in them.

I'm using aperture by the way.

To be able to sharpen certain areas only, you need to have layers and layer masks.

You do not have to have layers.

In LR in the Developmment module under sharpening, hold "ALT" key while adjusting the mask slider and presto. Sky instantly eliminated from sharpening much more quickly than layers in PS/PSP5X or adjustment brush in LR/ACR.

I don't know if Aperture does. PS does and it's quite easy. Copy the original layer to a new layer, sharpen the new layer and then use a totally black mask over it. Paint with white on the mask, with a variety of opacities to get the required degree of sharpening over different areas from no sharpening (black on mask) to full sharpening (100% white opacity on the mask).
