Basics Photography 01: Composition by David Präkel
Aimed at beginners (me, really), this book provides a very basic overview of how to approach composition in photography. Chapters include formal elements, space, time etc. and present info in a bite-size format, two pages each for topics such as perspective, scale, form, structure, patterns, color, and motifs. Most of the treatment of these subjects could undoubtedly go a lot deeper (some felt quite banal), but I did learn a few things and will hang on to this book for future reference. Glossy pages throughout with many inspiring images by renowned artists illustrating the concepts at hand well.
Even for people starting out with photography who want to look into the rules and science that make the craft tick, I would say search for something more substantial.
