Very nice work. To my old eyes, the last one is a little lost in the background. Perhaps darkening the twig a bit or sharpening the subject would help?

I'm looking foreword to doing some focus stacking. Have to get my macro lens back from a friend. Of course that means I have to return the one I borrowed….

Thanks Justan. The subject is actually razor sharp in full-size, so I think the problem isn't the sharpening (nor even your old eyes!), but rather the loss of detail that has come from 2 "resizings." I actually exported this to a 950x633 .jpg on Flickr ... but it seems like this Luminous message board automatically "resizes again" ... so that now it is an 800x533 image (and I don't think this helped much).

Combine that with the fact that the Twig Crab Spider is a highly-camoflaged spider ... and when you stick him on a lichen-covered twig, why he can be awfully hard to see ... which I think is the whole idea behind his camoflage ;D

Can't wait to see your work!

Of course. I made almost the same comment regarding loss of detail in one of my images due to the original 92% size reduction to get it on the web, and then the 2nd reduction done by the forum software. On the other hand, i could probably benefit from some glasses to use when at the computer.

It is a cool capture. If the green background were removed so that only the twig was showing it would become a pure abstract. I bet it would take most a while to figure out what they were looking at.

Exactly how long is this spider? An inch or half that or ??

Btw thanks for your kind comment about my Seattle pano.

Exactly. In truth, there are a million little "details" to that particular spider which simply have to be seen "full size" to appreciate. The other spiders (with a possible exception of the Ground Crab) are pretty simple-colored by comparison.

Thanks. I like the green background because it kinda blends with his own coloration. It's really hard to see these spiders in the wild, regardless of the background :)

Oh no, it's much smaller than that. Maybe 1/4" (1 cm) or so ...




Btw thanks for your kind comment about my Seattle pano.

My pleasure, it is gorgeous!


Thanks again,

Jack
