This macro photographer uses a technique you need to try – 32 images later, he revealed extraordinary hidden detail now recognized in prestigious close-up photo challenge

Photographer Jacek Hensoldt's work focuses on "the little wonderful things that we usually don't notice." To capture the hidden complexity of the macro world, he uses a powerful technique that brings out extreme details in tiny subjects: focus stacking.

Hensoldt applied this technique to capture Parasite – an image that was selected as a Finalist in Close Up Photographer of the Year's 'Death & Decay' challenge.

The photo reveals extraordinary detail in a cluster of shield bug eggs parasited by the wasp Trissolcus semistriatus – with one adult already emerged and others developing inside the remaining eggs.

Hensoldt says, "This is a cluster of shield bug eggs parasitised by the wasp Trissolcus semistriatus. The females lay their eggs inside the host eggs, where the larvae feed on the contents – the death of one becoming the prerequisite for the life of another.

"Through the translucent eggshells, the tiny heads of the developing wasps are already visible; in some, you can even distinguish compound eyes and antennae. One adult has already emerged but seemed in no hurry to leave without its siblings, which allowed me to photograph the scene at a relaxed pace.

"The adult wasps are only 0.9–1.3mm long and completely harmless to humans. What fascinates me most is how symmetrically the eggs are arranged. The final image is a focus stack of 32 frames merged in Helicon Focus."
