Oppose We already have a featured picture of a dragonfly's compound eyes which IMO thanks to better sharpness shows the compound eyes much better. --Fir0002 05:55, 14 August 2007 (UTC)[reply]

Info - But this is a depiction of the whole head, not of the compound eyes only. Alvesgaspar 09:46, 14 August 2007 (UTC)[reply]
Comment - Why is the eye so blurry, especially on the lower half? Is it simply a trick of light that the lines can't be seen, or what? I'm not saying it's a problem with the photograph, it's just curious. --Golbez 09:25, 14 August 2007 (UTC)[reply]
- I have no idea but this has happened with all my dragonfly pictures of this species. I supoose it has something to do with the fine strutcture of the lower part of the eye, which is not resolved by the sensor. Alvesgaspar 09:46, 14 August 2007 (UTC)[reply]
Weak Oppose original. The image appears to have poor quality post-processing - is it noise reduction? The image appears very clean but there seems to be a sort of jagged posterization most noticable on the legs but visible across the image.

- It is not the result of post-processing, the "painted-like" parts already appear in the raw file. Alvesgaspar 11:43, 14 August 2007 (UTC)[reply]
  - Strange. I agree with Dschwen that it might be in camera noise reduction (don't use it - it isn't necessary. There are better post-processing noise reduction tools available!) then. Still a good image for use in the article, but it has quality issues. Have you noticed the same effect in other images? Diliff | (Talk) (Contribs) 14:50, 14 August 2007 (UTC)[reply]
    - I don't know what it is, but it looks similar to the effects of a median filter to me. thegreen J Are you green? 01:52, 16 August 2007 (UTC)[reply]
Oppose - not a bad macro but we have the same subject already featured at better quality.--Svetovid 12:50, 14 August 2007 (UTC)[reply]
Oppose for the DOF/resolution/smoothing effect. Maybe it is in-camera noise reduction? --Dschwen 14:42, 14 August 2007 (UTC)[reply]
Oppose per above. Still a cool shot, though. --Peter 14:58, 14 August 2007 (UTC)[reply]
Oppose; the picture that Fir0002 refers to is better, methinks. Only thing this one has going for it might be its superior colorfulness. Unschool 01:03, 16 August 2007 (UTC)[reply]
Comment - Before the nomination is closed with no glory there is something I have to say: the comparison with Fir0002's picture is not fair. First because this is a depiction of the whole head, taken from a different angle, and not just of the eyes; and secondly because the pic was taken "in the wild", with wind and direct sunlight, to a very alive and nervous animal. Under this conditions the tripode is useless because we have to approach very closely to a moving subject in order to get the maximum magnification. - Alvesgaspar 14:46, 17 August 2007 (UTC)[reply]
