Danke, lieber roused. ;-)
Yeah, you're right. The photos are edited as a collage.
But the used photos - except for the cover picture - are not edited in themselves.
On the 1st photo I took the liberty of slightly increasing the color saturation. ;-)
I will correct this info...
Oh no Andy, I didn't mean that!
I meant I always edit my photos ;-) I simply can't resist, but I greatly admire all the photographers here who are purists.
