The RAW capture of this of this photo made with a Canon 5D Mark 2 was converted to a JPG in Photoshop using Camera RAW 6.7.1. Then in Adobe Lightroom the image was corrected using a Lens Correction profile on full auto. Then it was back to Photoshop to use the Nik Collection HDR Efex Pro 2 for some High Dynamic Range work. The Nik collection was purchased by Google, and is now offered by them for Free.
