La fotografía en la actualidad

La fotografía

La fotografía ha evolucionado con el pasar de los años, pero conservando su concepto; por ejemplo en el antes de una fotografía podemos mencionar: la copia en tonalidades de blanco y negro mostrada en una exposición y en el hoy la reproducción de una fotografía a color en algún texto o la imagen que emerge de un computador, podemos decir que esos son los ejemplos comparativos más significativos del antes y el después.

En la fotografía hecha a color existen tres capas de matices o colores, cada una de esas capas es sensitiva a uno de los colores primarios y la combinación de estas tres capas o colores tienen como resultado la imagen en color.

El escáner y la cámara son dos medios u objetos por donde se pueden obtener imágenes o fotografías, tanto el escáner como la cámara para obtener dichas imágenes o fotografías tienen su origen en un contexto analógico y tienen un solo fin, crear un archivo digital.

Gracias a que existe la digitalización se pueden hacer combinaciones de archivos de diferentes comienzos, todos poseen un tipo de información, unas imágenes y un lenguaje.

La imagen digital está conformada por una central de pixeles, que se observa en el monitor a medida que se pueda agrandar la imagen, se pueden guardar en la memoria del ordenador y hasta se puede enviar por el internet.

Las cámaras analógicas y digitales

Muchos fotógrafos manipulan cámaras analógicas de diferentes modelos y no surge ningún tipo de inconveniente, los problemas surgen cuando el cambio es de una cámara analógica a una cámara digital, porque entre ambas cámaras existen bastantes e importantes diferencias, por lo cual se necesita un tiempo prudencial para adaptarse a las nuevas funciones que posee la misma.

Cámara antigua.

Entre las diferencias importantes que se pueden nombrar entre una cámara analógica y una cámara digital son las siguientes:

– La cámara analógica enfoca los rayos de luz sobre el negativo. La cámara digital es capaz de analizar la luz y lo interpreta en forma numérica o dígitos por medio de un sensor electrónico.

– La cámara analógica reúne los rayos de luz sobre un plano obteniendo así una imagen enfocada que es donde se encuentra la imagen. La cámara digital como tiene una tarjeta de memoria que puede ubicarse en cualquier posición dentro de la cámara, ofrece muchos medios para el diseño.

– En la cámara analógica el negativo de la misma cumple dos funciones que son el de captar la luz y la segunda es guardar la información. En la cámara digital para poder realizar todo el procedimiento que hace la cámara analógica, ella realiza tres pasos: primero analiza la luz; segundo hace la interpretación de dígitos, y tercero y último guarda la información creada en un medio de almacenamiento que normalmente varía en cada cámara.
