First I apologize if this is in the wrong forum.

Taking some macro shots this weekend and I finally think I may have a good one. In particular I would like your opinion as to the sharpness of the image. All other comments are also welcome.

    Hello Ivan.......and welcome to Dgrin. thumb.gif Sharpness? Seems o.k. There are just so many different variables to really make a "quality" assessment on the sharpness. Nice shot and it looks sharp enough for online use (to me). thumb.gif

    foliage
    nice image -seems sharp to me-nice subject-it looks like an emperor gum moth caterpillar that we have down here-the only thing i can suggest to improve the shot in future is to consider your background for studio macros-some foliage in the background ,choose carefully so that it does not act as camouflage,will give a more natural "in the field' look to your pictures.

    You sharpened this image, didn't you?

    I need an answer to that before I'll comment on the sharpness of the lens itself. For that kind of test you need some comparative images. If you're just asking in general, I'd guess you went a little overboard with the sharpening. The leading edge (left) of the large green leaf on the right of the image is quite distracting actually. The spines of the caterpillar are suffering from the same plight.

    Maybe someone here can use some technical terms, but I can tell an oversharpened image when I see one.

    Where's Rutt when you need him???

    (and welcome aboard, that is otherwise a FABULOUS photo - that smooth consistent baby blue background is very nice. mmm mmm)

    Ok- Yes I did some sharpening on the original image. Here I have attached the same photo that has only been converted using ACR and then saved as a jpeg.

    As to the other comment as far as controlling the background in a studio shot....the picture was actually taken outdoors :-)

    Hmmm, I don't see much of a difference.

    There still seems to be some "artifacts" on that leaf edge and in the spines. I would still look at that and call it oversharpened, but now I'd be wrong. I wonder what it is?

    Anyone else care to comment?
