This time no error: pinhole. And again (why didn't I see that in the picture post Kern Aarau below? ) the "Linhof" logo clearly visible. I used my hand as shutter, this will be the reflection of that logo, very strange but possible. But if anyone has a better explanation I'm very interested!

PS This mill is called "SeldomRest".
(And look at flickr photostream erwinruys for the better, right explanation...)
And YES THERE IS another explanation (possible) look at May the second!
