Some weeks ago I was out with Javi to take some photos of him playing football. It was just around sunset and the sky got extremely beautiful. I could not resist to raise my camera up.
Increasing both the black value and the vibrance in lightroom to 50 was what made this photo pop, resulting in this deep blue tone.
Photo data: Pentax K20D with DA 18-55 AL II lens at 18mm (this lens was 55 Euros, and is so much better than the kit lens I had with the K100D. Better sharpness, contrast, everything), f7,1 at 1/200 second and ISO 200.
