On first picking up a camera, one might think that it is for photographing things. However, in the purest sense, light is the substance captured by a camera. In this stunning gallery of photographs, landscape photographer Fran Halsall explores the elements that make up a great picture. This is a book not so much about technicalities as about ways of seeing, making it an invaluable and accessible guide for anyone who wishes to take landscape photographs or who is interested in the mysterious distinction between a decent image and an amazing one. Halsall's clearly articulated commentaries on her own photographs, divided into three sections - `Light', `Form' and `Time', reveal her sensitivity to nature, attention to detail, boundless patience and intelligent analysis.
