[Note Guidelines] Photographer's Note
Even though their descendants are now smaller, they still have large compound complex eyes with very wide-angle vision to allow them to see as they fly forward and backward. Like other insects, dragonflies have to position their eyes by changing their body orientation, since their eyes do not move. Each of the dragonfly's compound eyes is made up of about 30,000 eye sensors, so they have better resolution than many other insects. The overall photoreceptor density can be about the same as humans. However, since dragonflies' eyes are much smaller than human eyes, they do not have as much overall resolution and sensitivity. Using binocular vision as humans have, dragonflies are able to estimate distance based on the distance between their eyes.

A fine capture showing the compound eyes in great detail Aytül, as evident from this capture, the upper parts of the eyes have bigger and less numerous ocelli, thus that part's resolution is much lower than the rest of the eye which have a much larger number of smaller ocelli, the sum of which have quite a larger resolution. Why it is so, I'm sure you will be able to figure it out!
Cheers,
Mehmet

Hi Aytul,
this was very close, All cells are well seen but I think
you had cropped it a bit to hard or it's over-sharpen.
Fine POV and nice composition. A interesting not.
Well done.

Hello Aytul,

This is a very fine macro of dragonfly's head. The DOF you have chosen is very good keeping most of insect's head in focus. The sharpness you have got for rendering eye structure is impressive.

Thank you for sharing,
Cristian
