Reading Photographs – Richard Salkeld
A useful book looking at the theory and meaning of images, it includes a number of case studies and various genre. A good starting point in understanding theory.
Behind the Image – Anna Fox and Natasha Caruana
Another book in the creative photography series, this one focuses on research in photography. I found this really useful in starting out and trying to piece my multitude of thoughts together in a coherent way. It looks at planning and developing your research as well as practise and reflection and explores the ways to present this.
