I find watches are very suitable for this "mini assignment" for one.
Come'on. It's just for fun ! And it's very easy. :D
The Setup
All photos are shot handheld with the Olympus OM-D E-M5 camera and Panasonic Leica 25mm f1.4 lens, minor edits in Lightroom CC. The watch is put inside the ProoCam Mini Studio Light Tent.
