    One of the Acorn Weevils. The long snout is used to bore into an acorn and then the eggs are deposited in the hole.


    Shot in a lightbox, cropped, curves, contrast, smart and high-pass sharpening.

    Fascinating creature this!
    The subject's nicely lit, but the composition seems a little odd to me. Personally would liked more space on the top than the bottom :)

    Ken...wonderfully sharp and detailed! I agree that cropping from the bottom might produce a better crop!

    Wonderful subject a really interesting subject. I get the impression there is a good deal of noise especially when I look at the feet, perhaps this is a lot of selective sharpening?? Please correct me if I am wrong.

    Now that is one cool bug! Apart from the points already mentioned, you seem to be losing a lot of detail, while you still have considerable color and luminance noise (see snout and eyes). Is this a considerable crop or is it related to jpeg compression to fit the BPN limits?

    Hi Ken. This is one striking looking weevil with that very long "snout." I'm impressed that you got virtually everything within your DOF - and it gave you a great pose too! There are some good points raised above about detail, noise, and sharpness - I wonder if some of this may be due to shooting at f/22? (My macro lens loses a very noticeable amount of detail due to diffraction when I go from f/16 to f/22.) Being picky, I'm seeing some tiny bits of debris and/or sensor dust spots on the white background - this would be an easy fix to clean those up.

    Steve, you hit the nail on the head. By going to f/22 to try and get the entire bug in focus, the DLA of my camera kicked in and the image wasn't sharp. I tried to compensate with extra sharpening but obviously that didn't work very well.
