There were no installation orgies, but that's not even done in two minutes. For all the Orginizer functions I can not say anything, but I have not used PSE9 in PSE11 I will not use. The most important new feature for me is the Camera Raw part, this is revised, it is now the same technology that is used in Lightroom 4.x. The new Camera Raw part has experienced such an increase in quality that one is inclined to develop some recording of the past again. The rest of the functions ... I levels, I brush, I can use layer masks. Much more I do not need. This makes PSE9 good that makes PSE11 well.
With the current surface I can live, I found the surface of PSE9 but successful. PSE11 must be learned, just like its predecessors. Anyone starting from scratch in the world of image editing, is here from a high mountain. But it is worth it. There are also many manual on the net and in various magazines.
