In New Zealand, there’s a species of glowworm called Arachnocampa luminosa — commonly known as the New Zealand glowworm — that can be found in dark, wet caves. Photographer Joseph Michael made these insects the subject of a series of photos titled “Luminosity.”
Michael brought his Nikon D810 into a number of limestone caves found on the North Island of New Zealand and captured long-exposure photographs of the glowworms scattered across the cave surface overhead.
“The 30 million year old formations form a majestic backdrop to the bioluminescence of the glow-worms,” Michael writes.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
