Aren't these three mushrooms adorable? I feel like they're giving each other a big group hug, thankful for the muggy weather and daily rain showers we've had lately.

As far as composition goes, you really can't go wrong with grouping items in threes. That doesn't mean there has to be only three items in the photo. But that fourth little mushroom on the right doesn't count, in my mind. He's small, off to the side, and out of focus. When I look at the photo I see three mushrooms right away. By composing your photos using odd numbered items it keeps things from getting too symmetrical and creates interest. After I took this photo I checked out the Shutter Sisters Flickr Pool and found some other photos that utilize the Power of Three.

mayalu captured these gorgeous poppy's in a group hug too!

ojoyous1 did a great job recognizing this serene set up.

 If you have any examples of "The Power of Three", I want to see them! And so does everyone else. Leave your links in the comments!
