This is our entry in The Daily Post Photo Challenge: Experimental.
The following macro photograph shows the results of an experiment in which a red raspberry was illuminated from the inside. A sheet of black paper with a small hole was placed on a light table to provide the light source and the berry was centered on the hole. The berry was only about 1/2″ across but the image looks like an exploding star to us.
This photo was taken on November 17, 2017. Specs are:
Canon 100D, ISO 100, f/16, 30 sec, 100 mm
