I dont ususally reccomend any books....practice and fooling around are where I got most of my technique. But these books have enough solid knowledge in them to hone what I have learned by fooling around. VERY worth the time.

Color Theory...

More than you probably ever wanted to know about LAB editing

I only edited it with Curves and color balance in all the color channels/spaces.

RGB - Curves Only Each channel RGB
CMYK - Curves (each channel CMY&K) and Color Balance (In that order)
LAB - Color Balance and Curves (in that order) Each CHannel LA&B

I then lassoed the water with a feather of about 50PX and coppied it to a diffrent layer and played with curves in RGB at the end to get a bit more reflection from it.

Flattened it and sharpened it.

Took about....15-20 min.
