Dan's mugshotDaniel H. Bennett was born in London in 1965 and lived in England until moving to the United States in 2000, settling in Northern Colorado.

His interest in vision and observation of the behavior of light has been life-long. On a trip to France as a young man his hosts called him “Monsieur Tête-en-l’air” (Mr. Head-in-the-air) due to his always watching for halos, rainbows, sun-dogs (parhelia), etc. He was particularly influenced by a book written in 1939 (published in English in 1954, Dover) by Professor M. Minnaert, called The Nature of Light and Colour in the Open Air. A Field Guide to Time-Varying Light Sources was conceived as a modern successor to that book, and adopts a similar approach, while revealing the secrets of modern light sources.

Daniel is married with four children, a motorcycle and two accordions.

Here's my blog, where I'll write articles of interest, things I've learned, tutorials, suggestions for lights to go look at, musings, etc.

Today my book went live on! After four years of working on it (not all the time, of course), and a major push over the last three months or so, it's finally a Real Book! With Pages, and a Cover and Everything!

I am sooo excited!

The book is published through CreateSpace, which is a division of Amazon which allows people to self-publish. The cool thing is that the book is printed on demand - i.e. when someone orders a copy, a copy gets printed, bound and shipped. This is wonderful, because there's no need for me to fund a print run, no up-front inventory, or anything!

In a few days' time, it'll appear on Amazon's websites in the US, Canada and Europe.

This book is totally a labor of love - observing time-varying lights has been an interest for me all my life. So it's a wonderful milestone in my life to see it in print. I am one happy guy. :)
