Thanks for posting!
Personal dream on photography, night and long exposure shots.
This is the reason I'm trying to sell my G12 to by a dlsr camera with a remote control...hehehe
I think the best choice is the DSLR camera for taking picture like this.
The only choice!
I think not the only. There are some kind of softwer which linking pictures (for example 30 picture) and made similar picture like this.
