My original vision had been to take a photo of an empty swing, but that didn't work out. First of all, swings move, which makes it very hard to get a crisply focused image. Second, no matter what angle I shot from, there were always distracting elements in the background. So much for my original vision.
(Did you know that there are quite a few unusual examples of playground equipment out there? A Google search for "creepy playground equipment" brings up a startling array of images, such as these.)
I also took some close-ups of the merry-go-round. I don't think this is "tack sharp", though -- the front seems in focus, but the back is somewhat less sharply focused.
I took some shots of the jungle gym and the steps up to the slide, too, but nothing emerged as a strong composition. Finding good photos can be challenging! After being out in the snow for over an hour, my socks and the knees of my pants were soaked, my feet were cold, and I packed it all in for the day.
Lessons learned: Your original vision may or may not work out; be open to other ideas. And dress for the weather.
