Engagement photography.

It is one of the more enjoyable photography experiences I can think of. The stress level is low. The opportunity for creativity is high. And, if I have a positive chemistry with the couple(which is pretty much always the case), I get to humorously hang with people and try to get some natural, hopefully photogenic shots of my friends. It's a big win for everybody pretty much every time. I think I would even enjoy it with a couple I don't know simply for the challenge of meeting them and hopefully improving their days. A fun challenge, indeed!
