Cómo utilizar el flash incorporado

Distancia y apertura cuando se utiliza el flash incor- porado

■Es necesario establecer un criterio entre el número de guía, la apertura y la distancia cuando se dispara con el flash. Calcule y ajuste las condiciones de disparo si el flash no es suficiente.

Cómo calcular el valor de la apertura a partir de la distancia de disparo

La siguiente ecuación le permite calcular el valor de la apertura para las distancias de disparo.

Valor de apertura utilizado F = Número de guía ÷ distancia de disparo

Ejemplo)

Cuando la sensibilidad es [ISO 200] y la distancia de disparo es 6.1 m, el valor de la apertura es:

F = 18,4 ÷ 6,1 = 3

Si el resultado de la ecuación (3, en el ejemplo anterior) no está disponible como apertura del objetivo, suele utilizarse el número más pequeño (2,8; en el ejemplo anterior) que más se le aproxime.

Cómo calcular la distancia de disparo a partir del valor de apertura

■Las siguientes ecuaciones le permiten calcular la distancia del flash para los valores de apertura.

Distancia del flash máxima L1 = Número de guía ÷ Apertura seleccionada Distancia del flash mínima L2 = Distancia del flash máxima L1 ÷ 5*

*El valor 5 usado en la fórmula que hay a continuación es un valor fijo que se aplica solamente cuando utiliza solamente el flash incorporado.

Ejemplo)

Cuando la sensibilidad es [ISO 200] y el valor de apertura es F4

L1 = 18,4 ÷ 4 = aprox. 4,6 (m)

L2 = 4,6 ÷ 5 = aprox. 0,9 (m)

Por lo tanto, el flash se puede utilizar en una gama de unos 0,9 m a 4,6 m. El flash no se puede utilizar cuando la distancia es menos de 0,8 m. Cuando el flash se utiliza en una distancia de menos de 0,8 m, causa el viñeteado en las esquinas de la fotografía, la luz se distribuye de modo irregular y la fotografía puede estar sobreexpuesta.
