Please don't comment as this isn't my photo I just had a play with Christina's photo @christinav as she wanted to know how to take out a kink on the horizon.
Not the best result but you can take out the kink using the clone stamp in Photoshop. Just click to the left of the kink and then move the mouse to over the top of the kink, click the mouse and it will merge. You can't do much with the waves when using photomerge because on each shot the ocean is moving.
I like what Babs did with it too.
