Looking in the window

At work, Trees

From my office window in the background, I am fortunate enough to get both views of trees, and when the light is right, reflected views of trees. And a miner bird who thinks there’s another miner bird there.

Although it makes sense physics wise, it still amazes me when taking a photo like this that I need to set my focal distance at how far away the tree is from the window, not how far I am from the image on the window. Cool, eh!
