Utilizing an External Flash to Freeze an Object
It can be quite frustrating when the lighting conditions are insufficient when shooting, which makes it difficult to shutter speeds fast enough to freeze a photo’s object. When encountered with such a predicament, a flash (whether it be the internal camera’s flash or an external flash unit) can be used to remedy the situation.
A flash has a relatively short flash duration, usually around 1/1000 – 1/20000 seconds. The flash duration is the duration of how long the flash illuminates a subject.
Because of this short lighting duration, it is possible to freeze the object of the photo, even with a relatively slow shutter speed (1/60 second, for example) in a low lighting condition.
In brightly lit environments such as outdoors in the sun, this trick does not apply because a slow shutter speed will capture an object’s movement instead of freezing it. Read the rest of this entry »
