Concepts in Photography

Flash

Light is one of the most important components in photography. It is not easy, however, to have an enough amount of light anytime and anywhere. Making use of a flash allows you to optimize light settings and create a variety of effects.

Flash, also known as strobe or speed light, helps to create adequate exposure in low-light conditions. It is also useful in light-abundant situations. For example, flash can be used in compensating the exposure of a subject’s shadow or capturing clearly both the subject and the background in backlit conditions.

Flash guide number

The model number of a flash refers to the flash’s power, and the maximum amount of light created is represented by a value known as a “guide number.”The bigger the guide number, the more light is emitted from the flash. The guide number is achieved by multiplying the distance from the flash to the subject and the aperture value when the ISO sensitivity is set to 100.

Guide number = Flash to Subject Distance X Aperture value

Aperture value = Guide number / Flash to Subject Distance

Flash to Subject Distance = Guide number / Aperture value

Therefore, if you know the guide number of a flash, you can estimate an

optimum flash to subject distance when setting the flash

manually. For

example, if a flash has a guide number of GN 20 and is 4

meters away from

the subject, the optimal aperture value is F5.0.
