With the sun peeking in and out of the clouds around sunset, I had some color issues with this composition. I couldn't find a satisfying white balance. Well, why not go Black and White with it?

So, some technical info about the photo: f/22, 2.5 seconds, ISO 160 with an ND filter. 

For basic processing, I dropped the highlights and raised the shadows, then set white and black points to bring back contrast. This spreads the histogram across the spectrum. Then I grabbed an adjustment brush to dodge and burn. I brushed the brighter parts of the rocks and surf, making them lighter, and darkened parts of the rocks.
