Gemma Padley's The Women Who Changed Photography: And How to Master Their Techniques delivers brief, punchy profiles and incisive assessments of what is revolutionary about these underappreciated photographers. In short chapters, Padley presents 50 women--some well-known, some all but unknown--from all over the world, born from 1799 through 1992. Profiles and portraits are followed by photographs, with Padley's instruction on how to mimic what is special about the work. This includes technical advice (how to combine and blend portraits; hand-tint a photo; play with angles, color, and flash) and the conceptual (how to use photo stories to raise awareness on an issue). Photographers include Anna Atkins, who "privately published the first book to be illustrated using photography," and Anne Wardrope, the "first woman in America to photograph her own nude body." They work in documentary, portraiture, art, photojournalism, and cover war, fashion, conservation, and more. Wide ranging and diverse, with fascinating storytelling, these contents are visually stunning and technically detailed, and will please readers with a variety of interests. --Julia Kastner, blogger at pagesofjulia
