What about focus? It does not look like everything in frame is in focus and the focus point will change, so I would assume you have to use manual focus and set the aperture for a reasonable DOF. Is that correct? AF can't work since you'll miss the shot by the time the lens has focused.

A slightly different alternative...

Check out your flashes durations at certain power levels... the Metz 58-af1 I used for these has duration of 1/33000 second at 1/256th power (gn of about 1 :) )

So, using the off camera shoe cord I put the flash very close to the bowl and triggered the camera (set to 1/250th) from the pocketwizard... you can watch drops falling and trigger pretty accurately...

This is an ancient thread and the posters probably pulled the images from wherever the source was that the links pointed to.

If you are interested in a complete solution for high-speed photography, please check Universal Photo Timer (see www.universaltimer.com (external link) for more information).

The timer is an integrated flash and camera trigger controller.

The timer allows to set a delay with a resolution of 0.1ms. The pictures below illustrate some of its uses.

You can use the built-in microphone or an external sensor as your trigger source. The external sensor could be as simple as a photo-transistor. You can use a standard off the shelf laser pointer as your light source.

The unit provides many other functions: For example it can act as a flash slave or a programmable camera infra-red remote. Programmable camera remote allows you take multiple repeated exposures for time lapse photography or capture long time exposures.

Interesting topic; I never realized so much went into these shots.

Here's a pic I took handheld with my old Nikon 5700 P&S with built-in flash:

Excuse me my stupid question (pretty new at photography) but how is the shot actually taken? You open the shutter, wait for the flash, and then close the shutter manually?
