My first thought when I saw the theme Details was Macro. That lens that allows us to see those things we normally would not get too close to!
Like Bees for instance. I am allergic to them, so not a good idea to get too close to them but without my macro lens I would not be seeing these Bees this up close and personal.
You don't notice the details that make Macro fun on the Bee without getting up close. Things like the tiny veins on the wings or the articulated joints of the legs. The Bee's Knees!
Like April Fools Day coming up, the Macro fools you into feeling like you are a lot closer that you actually are, and its all in the details that are revealed that is so cool.
