[Note Guidelines] Photographer's Note
Jumping spiders have very good vision centered in their anterior median eyes (AME). Their eyes are able to create a focused image on the retina, which has four layers of receptor cells in it.[3] Physiological experiments have shown that they may have up to four different kinds of receptor cell, with different absorption spectra, giving them the possibility of up to tetrachromatic color vision, with sensitivity extending into the ultra-violet range. Color discrimination has been demonstrated in behavioral experiments.

The principal eyes have high resolution (11 min. visual angle) [1], but the field of vision is narrow, from 2-5 degrees.

Because the retina is the darkest part of the eye and it moves around, one can sometimes look into the eye of a jumping spider and see it changing color. When it is darkest, you are looking into its retina and the spider is looking straight at you.

Excellent shot, and excellent POV/Composition, this is a photo that immediatedly draw the attention to the eyes. well done

Hello Leo,
This is a very impressive image. I like those great details and this usual eye contact :-) Colors and lightning are great too. This is very well done with excellent notes and it looks from being drawn from a cartoon :-) Thanks,

Hi Leo
I am really amazed with this picture! What an excellent macro!
Those eyes looks like crystal balls! A stunning image.
Congratulations and TFS.

Bonjour Leo,
Tu as réussi un cliché incroyable des yeux de cette araignée, très instructif sur l'anatomie de la bestiole. En plus, ta photo est un modèle de cadrage : symétrie parfaite et très bon traitement de la lumière.
Salutations

Leo,

Brilliant close up. One can see the retina in the eyes. Great level of details. You chose the right aperture to get most of the spider face in sharp focus. TFS.

Hello Leo,

That haircut! Those sunglasses?Is this a moviestar? Planet of the Apes? Wow what a shot! I find the rectangles in the eyes a bit unusual but a very impressive macro, Tfs, Jay
