Ideal help in wide-angle shots

DxO ViewPoint (in version 2.5) is the standard perspective correction, as it offers almost every EBV software, far beyond.
The correction of converging or drifting apart lines completed the program as well as many others, that would be no reason to buy.
But then it gets interesting by the following features:

- Lens and camera-specific correction (automatically) by loadable modules, Viewpoint analyzes the RAW image and then loads from a database the appropriate modules.

- Special adjustment options for extreme wide-angle shots through selective equalization of the outside areas of the image.

- The operation is really extremely simple and intuitive

These opportunities are really awesome and I have not found in other programs so.
I can honestly recommend DxO ViewPoint, the wide-angle shots (especially architecture as well as landscape) win dramatically in quality. For purchase of DxO 10 incidentally upgrade is offered on the full ViewPoint functionality for 29. This is a real bargain.

Shortcomings in the performance, as criticized in a review, I could on an old quad-core computer not determine (slower than i5 CPU). On modern hardware (i7 CPU) runs the program as a bat out of hell and also with the huge 36MPixel files a Nikon D800.
