Sinopsis
Si quiere aprender a realizar sus propias fotografías digitales infrarrojas sin grandes esfuerzos y con resultados favorables, ha llegado al libro indicado. Tiene a su alcance el primer manual de fotografía infrarroja en castellano, en el que encontrará consejos, sugerencias y orientaciones de mano de un experto en el tema. Con él, aprenderá paso a paso el apasionante e invisible mundo de la fotografía infrarroja y conseguirá dominarla totalmente. Descubra todo lo que necesita saber para realizar sus fotografías digitales infrarrojas con éxito. Ginés Guirao es un apasionado de la fotografía, autodidacta durante muchos años. Completó sus estudios de fotografía profesional en el Centro de Enseñanzas de la Imagen (CEI) en Barcelona. Ha participado en diversos reportajes sociales en FORESA (Fotógrafos Reunidos, S.A.) y en concursos creativos, todo ello dentro del contexto de la fotografía química y analógica. Con la llegada de la fotografía digital, se adentró en el mundo del Alto Rango Dinámico (HDR) y durante cinco años perfeccionó su técnica, plasmada en el libro Todos los secretos de la fotografía en HDR. Desde 2017 ha indagado en la fotografía infrarroja, en sus diferentes longitudes de onda, y ha presentado en este libro, de forma simultánea, las técnicas que domina con resultados sorprendentes.
