I have had several requests to add more information about this photo, so here goes :
During our Sunday lunch, there was a huge downpour. Immediately after the sun came out, and for a few hours the weather changed wildly between clouds, rain, and sun (vive le printemps!).
I was staring out the window at one point, waiting for the clouds to go away so I could go take some shots of the drops on the flowers (like this one and this one - and more to come once I get around to it), and it suddenly occurred to me that I could try and take a shot of the little drops that were stuck to the window. I had already taken this a long time ago (plus many more), which showed me what hidden worlds drops could offer, so I started shooting away.
It's tricky to get the focus right on my little camera, but after about 15 shots I had a few that looked good. This was my favorite. I cleaned up some smudges on the window that distracted from the blurred background (there are still a few more I would have liked to remove) and flipped it upside down, but other than that I didn't touch the photo.
I think the reason these drops turned out so perfectly round was because of the sun that had suddenly warmed up the window, starting the evaporation process, and then the clouds came back, slowing it down. So this is captured somewhere in between. Also, I have no idea if there were some kind of special cleaning products used to wash the window that allowed them to stay so round... it's true that I don't often see them like that!
What you are seeing refracted is a wellhead that exists in the backyard of my girlfriend's parent's house, with grass and trees beyond. There is a flowerpot hanging off the right side. The well is long defunct, but they decorate it well with flowers and such, and if I ever get around to it I have a few other shots of it as well.
Thanks everyone for the amazing response - it's inspiring in itself!!
