This picture was slightly crooked to begin with so, using the beach as my reference, I grabbed the straitening tool and made it more level. I then let camera raw make some of its own corrections to the image. I didn't like how light it made some of the darker areas and shadows, so I brought those back down a little bit. I really wanted the blue and the green to jump out so I adjusted the saturation as well as the green and blue hues. My final step was to sharpen it just a little bit.
This picture had a lot of color to begin with so it was really fun to see how different I could make it. It was very tedious work using the quick selection tool (especially around the logo), but in the end I was pleased with the result. I love the contrast that this specific edit brings.
