Perhaps this isn't quite kosher on NR but I accidentally ran across this wedding photographer's website and was very impressed by his creative and unusual compositions. If you scan through his site you will find lots of ideas you can try yourself. He was a sport's photographer who now shoots weddings, perhaps giving him an unusual perspective.

Many people turn to PAD for inspiration. Consider the images on this website as extensions of PAD limited to the subject of shooting weddings. But many of the compositions could be used for shooting portraits as well. I though these images were worth sharing.
Perhaps others can post exceptional websites on other types of photography in this thread, if the NR "police" allow it. This is not advertising. None of us are going to hire this guy. We are just looking at his website so we can copy some of his ideas. That's all.
