I admire Ross Lowell's inventions enormously. His lights, while not as robust as others and so not so well suited to rental houses, are a great tool for the beginning owner-operator. I began with his Lowel Lights and moved up to his D-heads. I remember them all fondly, even though I no longer use them.After many years as a director of photography, I've begun to teach lighting and have been looking at book options for my students. So far the best book I've found on this topic is Blain Brown's "Motion Picture and Video Lighting". While the layout of Lowell's book is stunning, as are many of the images, Lowell approaches each section with long lists which to my mind do nothing to inspire the thinking eye. With great respect for Lowell, I regretfully report that for me his book is for the encyclopediast, not for the emerging eye.
