I wanted to post something that wasn't nature, but then I remembered a photo I took a few months ago while testing a macro lens. This is a closeup of a drop of water hanging from a lemon. Is not perfectly focused, if you close up you will notice that.
I sharpened It up a little with Photoshop Express and enhanced the contrast a little. (Actually I used a filter, I think it was called "Gusta")
Taken with a Lumia 1020 with manual focus and ... the rest of the settings on auto
Here is the result.
