Landschaftsfotografie – Der Meisterkurs
von Michael Hennemann

Michael Hennemann, ausgebildeter fototechnischer Assistent und begeisterter Traveller, spezialisierte sich als Fotograf und Autor auf Reise- und Outdoorthemen und berichtet in zahlreichen Büchern und Zeitschriftenartikeln über seine Touren.


In seinem jetzt vorgelegten Meisterkurs der Landschaftsfotografie zeigt er eine große Bandbreite eindrucksvoll fotografierter Landschaften. Das Inhaltsverzeichnis mit 7 Kapiteln wirkt nicht nur beim Überfliegen übersichtlich und gut strukturiert. Angefangen mit einer Aufschlüssselung der Landschaftsmotive und kreative Bildgestaltung, über Fototechnik, digitale Dunkelkammer bis hin zum digitalen Fotoarchiv und einer Anleitung zur Gestaltung eines professionellen Bildbands (mit der Gastaltungssoftware von CEWE-Fotobuch) und repräsentativen Wandkalenders.

Das dreihundert Seiten starke Buch ist angereichert mit vielen wertvollen Tipps und Tricks für Foto-Einsteiger rund um das Thema Landschaftsfotografie. Ob analog oder digital, Standard- oder Weitwinkelobjektiv, SW-Fotos oder IR-Fotografie, das Buch begleitet jedes Thema und jedes Motiv mit professionellen Informationen, sowie Angaben der Foto- und Aufnahmetechnik zu den jeweiligen Fotos. Hennemann zeigt in vielen Schritt-für-Schritt-Anleitungen seine Arbeitsweise und gibt nützliche Anregungen “als Einstiegspunkte für eigene kreative Experimente” so Hennemann.

Der Meisterkurs zum Landschaftsfotograf von Michael Hennemann ist ein gelungener Band der zeigen möchte, wie man bei allen Licht- und Wetterlagen, bei Tag und in der Nacht, an Küsten, in Wüsten und in der Bergwelt und mit anspruchsvoller Bildgestaltung optimale Fotos erzielen kann. Inklusive Archivierung (Metadaten und Stichwörter, Geotagging) mit Adobe Bridge CS4 und professionelle Nachbearbeitung mit Adobe Photoshop CS4.
