For those who are interested…
- This picture was taken with a Canon EOS 600D with Tamron 90mm f/2.8 macro lens. ISO 200, aperture f/5.6 to provide at least some depth of field, shutter speed was set to 1/160 although this is more-or-less irrelevant because the length of the exposure is actually determined by the flash.
- I used a Yongnuo YN-560 flash on 1/64 power to ensure that the flash duration was short.
- Drops were created by suspending a plastic bag from a microphone stand and making a small hole with a pin to make it drip at a steady rate in the same place each time.
- The green colour was entirely provided by the ring binder I used to bounce the flash off.
