[Note Guidelines] Photographer's Note
An ommatidium contains a cluster of photoreceptor cells surrounded by support cells and pigment cells. The outer part of the ommatidium is overlaid with a transparent cornea. Each ommatidium is innervated by one axon and thus provides the brain with one picture element. The brain forms an image from these independent picture elements. The number of ommatidia in the eye depends upon the type of insect and ranges from just a handful in the primitive Archaeognatha and Thysanura to around 30 thousand in larger Anisoptera dragonflies and in some Sphingidae among moths.

Ciao Sergio,
gran bella macro con la testa molto dettagliata. Complimenti.

Outstanding macro of the compound eyes, Sergio.
This is an unconventional perspective since most people do it from frontal point of view.
Thanks for sharing this great capture.

Hi Sergio, Excellent macro picture. I enjoy looking at the compound eyes. Very well done and tfs. JC

Hi Sergio.
Extraordinary macro shot. I am impressed a lot. Bravo. Fantastic reproduction of the dragonfly head and eyes . Colours and soft lights are excellent too. Well done and kind regards.

Hallo Sergio
What a striking image, and the details so crystal clear. This macro looks as if it has just been washed and hanged up in to dry. It is beautiful. I like the natural sunlight that emphasise the prominent details on the eyes and fine body hairs. Thanks for sharing. Best regards.
