I have recently “discovered” humanitarian travel photographer and educator David duChemin. He’s a pretty busy guy with NGO assignments all over the world, the well received book Within The Frame, two ebooks — TEN and TEN MORE (ways to improve your photography without buying more gear), a video podcast to go with his book, and a blog.
His writing is fresh and insightful, but remains lighthearted. Still, he cuts no slack in focusing his readers more on the why, the vision and the passion of photography as opposed to the with what. “Its not the gear. Its the vision.”
Not many people can talk about the art and vision of photography from a practical, not academic, point of view, but David does just that. I’d recommend trying one of his ebooks, maybe getting his book and certainly following his thoughts on his blog.
P.S. If you get it now, his ebook TEN, is still $5, but goes up to $10 on October 1st.

All of my basic lenses are constant f/2.8 aperture models and are generally accepted as pretty good glass (EF 100mm f/2.8 macro, EF-S 17-55mm f/2.8 IS and the EF 70-200mm f/2.8 IS). Needless to say, they are not small, nor light, and don’t work too well as “all around” or “walk around” lenses.
