I went much lighter on the editing of this one, than I usually do. It was mostly because I already liked the starting photo as it was, even with this more purple tint. So I left the white balance as it was, and just used two exposures, to create a HDR in Oloneo Photoengine, as I wanted to get more detail in few areas. And than just noise reduction, little contrast and sharpening and that was all :)
This is a HDR from 2 exposures, taken from the Tour Montparnasse in Paris.
