FLASHES
Flashes are devices used in photography to produce an instantaneous artificial light on a subject. It is used to lighten up the subject at a low-light shooting and capture quickly moving objects. A flash on a camera usually has a small battery, a gas discharge tube and a circuit.
There are different types of flashes and some are flash bulbs and flashcubes. Flash cubes are much smaller and modern and flash bulbs are much heavier.
Also there are two techniques for flashes and one is direct flash. Direct flash is an amateur way of lighting, used to supplement ambient light in order to lighten a subject close to the camera. The subject usually appears very pale and white due to the directness.
Another technique is bounce flash. Bounce flash is a technique in which flash is directed onto a white reflective surface to reflect the light onto the subject. The bounce in light creates softer, less artificial-looking illumination than direct flash. It creates more of a expanding and softer lighting.
Light Meter
A light meter is a device used to measure the amount of light or a proper exposure for a photograph, in photography. It usually contains a screen that shows which shutter speed and aperture should be used.
HOW TO WORK A LIGHT METER:First, you set the film speed on the meter, then activate it.
After activating, you hold the button in to make continuous measurements, moving around the subject. For more professional information, click here.
There are two types of light meters which are reflected-light meter and incident-light meter. Reflected-light meter measures the light reflected by the scene to be photographed. This is more widely and frequently used. Incident-light meter measure the amount of light falling on the subject using an integrating sphere. This one is less used and has a high chance of making mistakes.
