Photo challenge – please vote for us

Some weeks ago a friend of mine pointed me to an upcoming photo challenge about image manipulation created. It has been initiated by the biggest German computer magazine c’t. My first thought was to attend this challenge but I recognized that I don’t have any great images on my box and no time to work on that. But surprisingly a friend was visiting me over those days and we had some great shots in the Saxon Switzerland.

Given those pictures Silvia made a fake image in parallel without knowing about this challenge. Once I had seen the result I pushed here to subscribe to the challenge. After some talks and further processing steps of the image we have decided to take the challenge just for fun. About 3 weeks ago the first results have been posted to the online gallery and a public survey has been started. 139 of the best pictures can be voted by everyone and our faked image is in this list too.

Here a former version and not the final one on my Flickr account:

Surprisingly a former colleague and a friend of mine informed me today that we have made it to even show up on Woot – there are only 13 images posted. So isn’t it a call that we have good chances?

Please help us and vote for our image when you like it. We appreciate your help.
