Water mite (Hydracarina)
Taken with the mite in a drop of water on top of the slide (no cover). Not really a difficult subject, but they really move about rapidly and the legs go all over the place, and they seldom rest for long. So it took many shots to get one where the legs looked good. Then a second shot with the carapace in focus was "manually " stacked for DOF purposes.

Hello Charles!
a beautiful picture!. Did yo use your flash on the Canon (50D?) in live view
and in "silent-mode"? The exposition was automatically (TTL) or manually?
I am asking because somebody said that in live-view and in "silent-mode" it is impossible to use a flash (except one from Canon). Am I wrong? Could I use my old Metz-flash (Metz32CT4) with a new Canon D50 in liveview and in "silent mode"?

Franz,
This is my "standard" Vivitar 283 flash tube arrangement, manually controlled as seen at the bottom of this page.
Actually no flash of any type can be fired in "silent mode", since there is no flash sync signal provided. When a Canon flash is used (or the built in flash), the camera knows that there is a flash attached, and will automatically switch out of "silent mode" and cycle the shutter, synchronizing the flash appropriately.
When I use flash for active critters I use one of two methods. No live view. Set the custom function for mirror lock-up. Then as I am anticipating getting close to taking the shot, I first release the shutter once to lock up the mirror, and then a second time to take the shot. (It becomes second nature to work this way after awhile). If things are happening so erratically and fast that there may not be time to prerelease the mirror I'll simply use normal camera/mirror operation.
If you haven't already seen this post, a summary of live view operations in Canon and Nikon bodies can be found here.
