Photography Short Course – Flash Photography 2
A large fish tank filled with water standing on a table in front of a dark cloth background. A stand alone flash unit with a wireless trigger was positioned above and to the right of the balloon with the camera mounted on a tripod also positioned directly facing the tank. We held something in the water where we hoped the object would enter the water to pre focus, which meant all we needed to do was click the trigger.
The idea this time was to trigger the shutter just as an object was dropped into the fish tank. There was also a large glass vase filled with water and using a side flash, with a black or white card background to photograph objects agaisnt but unfortunately time did not permit me the opportunity to try this setup.
The pictures above show the result of those I caught as they dropped into the fish tank however there are many more pictures of empty tanks (triggered before entry) and tanks with the items laying at the bottom of the tank (Flash triggered late). What I learned from this simple exercise is timing and of course typical settings for using Flash to capture moving objects – to freeze a moment in time.
We repeated this experiment using a smaller fish tank but this time using a hand held Flash connected using a hot shoe adapter, connecting to the flash using a cable.
I’ve limited the editing to cropping and adding a tint using Lightroom 4, which can be downloaded as a 30 day trial version from Adobes website.
Camera Settings – Canon EOS 60D
None of these settings are set in stone but these seemed to give the best results.
- Camera set to Manual
- White Balance set to Flash
- Shutter Speed 1/125 to 1/250 (depending on which flash gun was used)
- Aperture set between F8 to F11
