Introducing the YS-D1 A New Standard in Strobe Technology
Normal sync strobe goes off 0 Shutter opening duration (sec.) Rear-curtain sync strobe goes off This type of synchronization, when performed at a slow shutter speed,
leaves the blur or the streaks behind the subject. The strobe light literally freezes the subject but it does so at the front of the blur, making the movement appear more natural.
A Tool Not a Goal Rear-curtain sync became popular in the 90s. Everyone was trying it and we saw lots of pictures made this way. Over time the technique was put on the back shelf to be employed more sparingly if and when the subject lent itself to this type of lighting. Used appropriately it provides another way to express yourself through
your images. As with any technique it requires practice and, sometimes, the results do not match the expectations of the photographer. Rear-curtain sync only makes sense when selecting slow shutter speeds.
Don’t bother if you are shooting above 1/15th second. Below that speed, it may become the right tool for your image. Rear-curtain sync must involve natural lighting within the exposure. So,
select an ISO and aperture that require a slow shutter speed for natural light exposure. Then, read your manual and learn how to select the rear/2nd curtain sync on the camera. Shooting in manual mode, make sure that the selected aperture and
strobe power level lend proper exposure. A slight over or under exposure by strobe may produce a better image to your liking. As ever, experiment, experiment and experiment some more. You may leave the camera in a fi xed position, even using a tripod, and let
your subject move. A second option is to pan or even follow your subject as it moves. Again, trial and error is part of the process in assessing the best option for the desired result. Try diff erent shutter speeds; generally speaking, you should not need to venture below 1/2 or 1 second, the latter being a rather long exposure.
Too Much of a Good Thing Like many things in life, this technique has its place, but don’t overdo it. A few years ago we watched a presentation by a photographer who was talking about a specifi c destination. All his underwater images were done in rear-curtain sync. At the end of the lecture Danielle felt like she had just eaten a gallon of ice cream. It was way too much! Happy Bubbles!
