Las fotos y fondo desenfocado

Las fotos con fondo desenfocado, fue una creación de la Sony, ya que la Sony fue la empresa pionera o fundadora como lo quieran llamar en el medio fotográfico, que iniciara con una nueva forma que la llamaron espejo traslúcido.

El espejo traslúcido, es lo que le permite al usuario que manipula la cámara, apreciar y percibir todo tipo de efectos. El más encantador, atractivo y popular es el poder de enfocar un objeto central y dejar el fondo del objeto borroso.

El nombre técnico que recibe el fondo desenfocado es el de enfoque selectivo. El enfoque selectivo, es aquel que sencillamente radica en disminuir la profundidad de la imagen, provocando que el foco se enfoque en un objeto central y el resto de la imagen se refleje en forma desenfocada.

Para obtener este tipo de efecto en las cámaras más sencillas, se pudiera trabajar con una función que trae que se llama Macro, que te ofrece un efecto un poco semejante al resultado que se obtiene de una cámara réflex.

Las cámaras que son más complejas, sarcásticamente, son menos mecánicas pudiendo permitir hacer más cambios, abriéndole la posibilidad al fotógrafo de elegir como se pudiera tomar una foto y jugar con las tonalidades.

Con una cámara réflex, el fondo desenfocado se logra conseguir reduciendo la distancia focal y agrandando la apertura del objetivo; solo es tener muy en cuenta, que el objeto que va a ser el objeto central, debe estar a poca distancia de la cámara.

Las fotos

A continuación les daré unos buenos consejos para lograr tal efecto en las fotografías:

1. Se debe tener una mayor apertura del diafragma, lográndose con esto, que al entrar mucha luz pero en muy poco tiempo, se logra una exposición correcta y se logra producir una profundidad de campo pequeña, obteniendo un el enfoque con menos elementos.

2. Un programa que puede ayudar a que determines la distancia para que hagas un buen enfoque, es el programa llamado Depth of Field Table, este programa ayuda a calcular en una forma determinada la profundidad del campo en relación con el objeto central.

El programa Depth of Fiel Table, pondrá a tu disposición una tabla que te ayudará a obtener una buena fotografía con una buena profundidad de campo, en esta tabla, te piden el tipo de cámara y el tipo de unidad de medición.

3. Otra aplicación que es para teléfonos, que también es muy buena y cómoda de trabajar, es un programa que se llama DOFMaster, ésta posee una tabla muy parecida a la que tiene la aplicación anteriormente nombrada, se debe colocar el nombre de la cámara que estamos utilizando, de todas maneras si no comprendes mucho la tabla que esta aplicación te muestra, la misma te ofrece también una opción gráfica donde podrás comprender con más claridad cómo funciona el programa.

Ahora no hay excusa para que puedas utilizar y experimentar con la nueva técnica del enfoque selectivo, solo debes tomar un poco de tiempo para comprender los conceptos y luego ponerlos en práctica, para luego saber dónde ubicarse para poder obtener una buena foto.
