From a Harry Krause Posting:

Are the skies in your photos not as blue as you'd like them to be?

No problemo!

Use color control points to repaint those pale skies the vivid blue*
you
would like them to be!

Just click the correct icon in the toolbar...

Click the sky...

Drag the size slider to size the control point...

Adjust brightness and contrast....

Save the image using the Save As option in the File menu...

It's easy!

* Or orange, if you want to give your photos that snappy off-planet
look!

(Yes, I have a copy of Capture NX2... :) )

Click the sky!

Not satisfied with the college you went to? No problemo. Just
suddenly graduate from an Ivey League School.

Ashamed of your wife? No problemo. Just make her 20 years younger
and bestow a medical degree upon her.

Embarrassed by your dinky little boat? No problemo. Give yourself a
lobster boat for that snappy off-planet reputation.

Humiliated by your lack of friends? No problemo. Become friends with
every president since Harry Truman and go to work for of one of them.

No problemo anywhere that can't be fixed.

It's easy. Click the sky!
