Effective use of Flash Photography
Did you ever put your flash unit in manual mode? Did you ever manually turn on the flash when taking a day time outdoor photo? For many the answer to both questions is “no”. For most amateur photographers flash is just a solution for taking photos when there is not enough natural light. Although a legitimate use of flash photography there is much more ways to efficiently use flash. In this article we will cover the various types of flash units available, the different scenarios under which they can be used, the advantages of using flash to achieve better photos and the common mistakes people do when using flash photography.
As with any other technology knowing how it works behind the scenes and what your options are can help in better utilizing it for your advantage. Flash photography has been around for more than a hundred years. It started with a dangerous and manually controlled technology that used a powder that was lit by either fire or electrical current. These flash solutions were both dangerous and hard to use since the flash was not automatically synchronized to the camera’s shutter. Modern flash units use an electronic flash tube that is synchronized with the camera’s shutter. When turning the flash on the photographer does not need to worry about flash timing - the camera takes care of it automatically.
There are two types of flash units: Internal and External. The internal flash unit is built-in to your camera. It can be controlled through the camera’s menus. Some low end cameras only allow the use of their built-in units. Some low end cameras and all high end cameras also allow the attachment of an external flash unit. External flash units are either attached to the camera’s body through a dedicated slide-in slot or are connected to the camera using a cable. They vary in strength – how much light can they generate for how long - and in mechanical characteristics – can they be tilted or skewed or are they fixed in relation to the camera’s body. Regardless of the connection type external flash units are electronically connected to the camera and are synchronized with the shutter.
