Here is another photo from Marek Miś of Suwalki of Poland. This pretty triplet image is actually tiny air bubbles from crystals of melted ascorbic acid, better known as vitamin C (though not a tablet or capsule). The technique used to melt the ascorbic acid is one that is used by a number of photomicrographers, as it is known to achieve unique and visually appealing results. The technique creates an almost limitless array of shapes and patterns with no rhyme or reason. This particular entry earned Mr. Miś sixth place in the 2016 Nikon competition.
