Two broken screws
Today’s picture is something of an experiment. I wanted to see just how small an item I could photograph. As a reference the graduations at the top of the image are mm markings on a ruler.
The story behind the photo: I was repairing a dining room chair today, and both of these screws broke as I was screwing them in, leaving the threaded part emedded in the wood of the chair.
For the photographers a few technical bits about the shot. 105mm macro lens + every extension tube I own. Appature F45 to get the depth of field. Exposure time: 6 minutes (yes I do mean minutes).
