Use your flash as a virtual shutter.
Without the flash the light bucket is almost completely empty.
So the flash is really the only source of light in an image like that one. Since the flash has an average duration of only 1/12000 of a second the flash becomes a virtual shutter -the fact that the actual shutter was open for 1/200 of a second doesn't matter, since there is very little natural light reaching the camera's sensor anyway.
So, in reality, I took the photo at about 1/12000 of a second. That’s why the image is sharp, even though I didn’t use a tripod. You can use the same “trick” to take photos of water drops (the subject of a future post).
