Thanks Bill. I'm not doing anything special. I do sharpen images for
the web a bit more than those that I print. After downsizing the file
that I saved full size, I'll usually add a bit more Unsharp Mask. About
60%, 0.8 pixel, threshold of ten. This is in addition to sharpening
done on the full-size image. Full-size (144 meg, 16 bit) images get
sharpened at 200% to the point where artifacts begin to creep in. The I
back off from there until they disappear. Sometimes I localize
sharpening. If I apply it overall, it's frequently on the order of
160%, 1.5 pixels, threshold of 11 or 12. I turn the sharpening in the
RAW converter down to 15 when converting.

Hi Paul,
I particularly like the frog photo. Question: I'm impressed with the
sharpness of your photos posted recently. Are you doing anything
special in
your editing process to account for it?

Subject: PESO: Sigma Super + magnifier + high speed synch
I went to the nature center yesterday to try the Sigma 500 Super and
high speed synch with a Kalt flash magnifier attached. The magnifier is
intended for lenses of 300mm or longer. I used my A 400/5.6 on the
*istD. I had hoped to get some birds, but they were in hiding for the
most part. I ended up shooting some wildflowers and a frog at the edge
of a pond. The wildflower is about the range for a nice bird shot. The
frog is a bit closer. The flower is f8 @ 1/1500. The frog is 5.6,
1/1500. I like the performance of the magnifier. It should give me a
reach of close to 100 feet even in daylight. Thanks to Bill Sawyer for
turning me on to that unit. The frog shows some specular highlights. I
decided not to PhotoShop them out of there, because I kind of like
them. I suspect that he's actually a prince.
