These two volumes use completely different methods for inspiring photographers of the natural world. The unique format of Developing Vision and Style contains a dialog among three admired British landscape photographers (Charlie Waite, David Ward, and Joe Cornish) moderated by editor Eddie Ephraums. The answers to his thought-provoking questions are illustrated with each photographer's work. The same questions are then presented to several amateur and professional photographers for their insights, again accompanied by examples of their work. The result is a stunning landscape photography tutorial full of a broad range of insights. Highly recommended for all collections.

Lucock's splendid volume covers the new technical possibilities of digital nature and landscape photography. The coverage encompasses advice on the digital workflow from hardware to software, understanding the rich, creative potential of the medium, the use of digital cameras in the field, and basic and advanced image-editing techniques. As a biologist, professional photographer, and experienced author, Lucock is uniquely qualified to have produced this highly recommended book.
