Thanks for your feedback! And thank you, Kevin for the translation! Very funny
I did 10 images in total. A zenit shot helped me to avoid a gap between first and last shot. And photoshops blending algorithm is great.
Furthermore i did some corrections of exposure and contrast in lightroom. and i used a head lamp to "paint" the rocks in the foreground a little with light.
On the national geographic page is a small making-of, unfortunatly only in german. (Kevin, if you use Babylon translation you will have fun!
Thanks and best regards,
