Default Eyes of dragonflies

Taking pics of dragonflies, esp. portrait of the head have often the impression that the eyes are out of the DOF. If you look at the pic you can see other parts of the insect which are surely in the DOF. So that the eyes must also be in the DOF. too. I often have this problem and I also have seen this effect on pics of other members of the WPF. Any ideas what is responsible for this effect?

Alfred,

There appears to be something wrong with your attachment. Firstly, it's not a dragonfly, and also, it's just a thumbnail that's too small to see anything.

Try editing your post and use the "go advanced" option. Scroll down to the "manage attachments" section and attach your picture.

Regards,

Duncan

Thanks Duncan,
It's my first text thread in this forum. I added two examples to show the effect I mean. I hope it will work now.

Regards
Alfred

I think with the side on view the eye is so bulbous that some is in focus and some is not, i.e. the DOF is not great enough to cover the whole eye.

DoF is shallow. I have a photo in the gallery that clearly shows the problem of DoF with damselflies. You'll notice that there is only a couple of mm along the central vertex that is in focus. On some of them even with the classic side view, if you get the near eye in focus the thorax will be out. So for those species you have to take a top down shot, or allow the loss of DoF to become a part of the shot.

Have a look at this image by LordV as it clearly shows the eyes of a damsel.

Amazing photograph, a combination of five images, shows what you can do with focus stacking

I think you are right. It's a problem of the DOF. The Nikon 8800 has only f/7 and I think the problem can only be solved by closing the aperture or changing the angle of the pic.

Thanks for your answers

Alfred
