His most recent project "Thicker Than Water: My Family in Photographs (1968–2012)" (as yet unpublished), collects decades of personal family photography. Covering as much of the variety of family experience as he can in a range of settings that includes (among others) the kitchen, the bathroom, and the backyard, Blau looks at both the ordinary and the extraordinary aspects of family life. This book provides Blau's perspective on the material narrated by Gallop in "Living With His Camera". He writes, "These pictures are spontaneous transcriptions of my experience, an ethnography of family life, a phenomenology of domestic emotion...By selecting a moment, then stilling and framing it, I try to retain some feeling of the event itself. At the same time, I use the abstract nature of the picture-making process to clear a space for reflection. These photographs are my part of a discourse. Notes to the people I live with and love".
