Hi Mark -

There's full technical data in my reply to Bill Sawyer.

I shot these at ISO 400, which helps even up the background lighting (the insect itself it lit largely by the flash - note the dual highlights in the dragonflies' eyes to get an idea of how the lighting parses out. The bottom highlight is the flash, the top is the sun.)

In some respects, digital is harder than film for this kind of shooting. I used to merrily shoot away with ISO 100 film hand holding the camera at 1/250th, and got seemingly sharp images. But the greater acutance of digital really brings motion blur to the fore - even shooting at 1/350 it's hard to get a crisp shot with the *ist-D handheld. So I use a monopod.

As noted, I used the A*200. I'm still using this bracket that I put together a few years ago -

Though the Pz-1p has given way to the *ist-D and the Sunpack flash has been replaced with the AF360FGZ.

The QR plate for the monopod goes into the camera's tripod socket.

Great stuff as usual. What ISO were these shot at?
After the (relative) success at my casual attempts at insect photography
last week I'm starting to get interested in pursuing this kind of thing
a little bit more...
