Hoy ha tenido lugar un eclipse solar parcial en el que la Luna a ocultadoun 75% del sol. Este es un fenomeno astronómico muy espectacular pero dificil de fotografiar. Aquí tenéis algunas de las imágenes llegadas de las agencias y que he recopilado con la ayuda de mi compañera Victoria Mouriño. Distingo tres tipos de fotografias: a) Tomadas con un teleobjetivo con un filtro oscuro fotografiando toda la evolución del eclipse, como se puede ver en los combos, b) Utilizando un tele y subexponiendo, jugando con las sombras y contraluces de otros objetos como pináculos, aves o aviones, y c) Fotografias de ambiente de gente con gafas protectoras, telescópios y demás. Espero que algún conocedor de este tipo de fotografía amplíe los aspectos técnicos de este tipo de tomas. De monento os dejo con esta edición del eclipse.
