David duChemin is a professional photographer, communicator, author, philosopher, teacher and traveler. He is also a prolific author who has a rather confusing series of websites and blogs.
He qualifies for my AoM mention for these two [of many] books because of their useful and non-technical jargon-free and inspirational content that will benefit anyone contemplating or running a creative business.
The man himself has a series of free podcasts on Youtube.
I was going to send him an email and yet he says he can be contacted only by Twit, Bookface and the usual other antisocial media sites ... which is a pity for those of us who abhor and ignore them. His books are available from Amazon and eBay.
