Thanks for the nice words and the time you took to look.
Shutterpup: I used Lightrooms output sharpening for screen with "standard" strength. Actually on some images the clarity has been put DOWN by me and been selectively restored on some objects of interest, but overall there shouldn't be much additional clarity applied, if at all. But: Some of the lenses I used have great sharpness, even if its old glass (Mamiya Press camera with according Sekors at 50 and 75 mm and the great 100 mm f2.8 lens - the kit I just gave up for a Mamiya 7 II kit). The scanning was done with a Nikon Coolscan LS 9000 at 4000 DPI WET MOUNTED, which preserves a lot of local contrast and totally removes Newton rings, not to say that film flatness is perfect then.
jalcocer: The image with the arches is one of my favorites as well. When I saw the light and the scene I was a little mesmerized - had a magic feeling, sortof.
Russ: I am sorry - but your color shift destroyed the image for me - good to see people have different eyes and taste.
Ivan: When I arrived at Sans Souci in the morning I met the Photographer who is doing all the official images for the Sans Souci administration, and most likely the images in the book you saw are from him. A very nice chap and we had a pleasant talk about photography and stuff when we were waiting for the light. He used a 4x5 inch tech camera and sheet film. And: Yes ! potsdam is an awesome place to take images. I hope to get there more often - I have family there.
Cheers
