How do you like my bug shot?
Taken Canon EOS 10D, 105mm F2.8 1:1 lens

This is just one of those little pesky bugs that annoy you in the garden :)

Should I have cropped this different?

Oops fixed link, in a hurry I guess.

It is a good macro of the bug - sharp, in focus, well lit and well exposed. The only problem I see is the big, out of focus, bright, distracting white rectangle in the background - it is worth paying a bit more attention to getting non-distracting backgrounds, generally, but particularly for macro shots.

Thanks Gordon, I was wondering about that when I cropped it. I may try later to do a better job.

I was really wondering how far down I could crop it before losing quality?

And thanks for the help!

i tend to find, that if the focus is spot on and there is no camera shake, the d60/10D/300D pics will look good right up to 100%.

it's really amazing.

Robin,
I like the closer crop; watch the sharpening, however, there is visible haloing. Try a multi-pass aproach with conservative settings.

I'am not trying to be argumentative but could you point out where you think there may be haloing?

This shot came out so all I had to do was Level adjustment, and a very small 25 - 50% USM.

I'am just trying to understand what you are seeing? for future reference.

check the underbelly of the insect, there is a little haloing going on

I checked the original and the edited version and there is some halo between the bug and the green leave on both the original and the edited version. I had to zoom in and magnify it a great deal in order to see it. So apparently it is nothing I did with USM.

The rest of it came out when I compressed it to (150k) for loading to DPC. How I can avoid that in the future I am not sure.

Robin,
The belly & front leg is also where I was seeing it. I agree that with those USM settings it is unlikely that it's due to USM, however if it was there originally it would have been enhanced by even the conservative USM.
I have seen this before on some of my shots with my ol' trust Nikon 995, but have not noticed it with the 10D-100mm/2.8 macro lens combination. But this is pretty much a 100% crop, correct? As such, it's "worst case", and it is still quite sharp =)
I've read a bit about "true unsharp masking" which can remove/reduce halos, but I have not had an opportunity to play with the technique. Here's a link to discussion of the technique.
