At first I had a lot of freeware tools Raw watched and tested. After trying the trial version of DxO Optics, the trial has detected and downloaded the camera and lens data and I had also discovered a one-hour learning video from the manufacturer on Youtube, it was clear to me - buy. After that there was in Pictures also a test in which my opinion also confirmed. The 6 version was probably too slow, but I had never in use. The 7 Series version is sufficiently performant and fast.
The corrections of the images is enormous and really makes a lot of. Until now I thought to my pictures that I already nearly the maximum abbilde with my camera. Best download and try the trial version.
I use a Nikon D7000 with multiple lenses. Software I use Photoshop Elements with an element +, Photomatix Pro and DxO Optics and am very satisfied.
