Environmental Portraiture
Author: Jim Cornfield
Publisher: Routledge
ISBN: 1317386477
Category : Photography
Languages : en
Pages : 325
Book Description
This unique book is a photographer’s guide to the powerful medium of the environmental portrait. It explores in lucid detail the many "moving parts" of this imaging style, including the techniques and creative processes that drive some of this genre’s finest contemporary practitioners. In Environmental Portraiture, author Jim Cornfield puts his readers behind the viewfinder to help them successfully master what he calls "the portrait photographer’s most high-powered tool." In a series of detailed tutorial chapters and study models, Cornfield unpacks every practical aspect of the environmental portrait scenario, including research, location scouting, lighting interior and exterior environments, props and wardrobe, lens selection, composition, color, and after-capture. Along with this wealth of comprehensive nuts-and-bolts information, the book probes the deep structure of environmental portraiture—the blend of a sitter’s backstory with the meaningful visual clues in their surroundings. He introduces such concepts as "portraitcraft," "cognitive weight," and "the ideas and emotions quotient," among the many dimensions of an environmental portrait that create eye-opening revelations about the person in front of your lens. A separate section of the book is devoted to a prestigious roster of contemporary environmental portraitists, specifically recruited for this book to explore in-depth selected samples from their diverse portfolios. They bring with them a score of insights, tips and fascinating anecdotes that demonstrate their individualized approaches to this versatile branch of the photographer’s craft. Written for professionals, amateurs and serious students of photography, this book is both a guide and inspiration to creating powerful, communicative environmental portraiture.
