The latest version of Nik softwares Color Efex pro has just launched and it looks pretty impressive. I have never used this set of filters before so did not know what to expect but the interface was easy to pick up as it works very similar to HDR Efex pro. The choice of filters is extensive 55 in total each with numerous adjustment options to suit all styles of photography. The new version allows you easily apply multiple filters to one image and the can be applied to the full image or specific regions.
