A riddle of a certain photo...

From time to time I turn to you with a request for help - when I cannot find the source of a photo or determine who is on it. And it happened, that thanks to your tips I got to where I wanted. Well, let it be similar now...

I have such a beautiful picture on my disc and I don't know anything about it. I would like to see if there are more. The signature adds little to the case: "Kuka Kuchler" - if I read it correctly at all. Unfortunately, I did not find anything under these keywords. Searching with an image also gets me nowhere.

From what it seems to me, this is a photo from a joint session of several photographers. Among others, German photographer Bert Kubik participated in it - once on his website you could find similar photos. If that was the case, the picture would be around 10-14 years old. I don't know if that's a good clue. If any of you know something about this photo is, just let me know in the comments. Thanks!
