This book was written in 1995, 1997 copyright, when most photographers still used film. There are not only no photographs but no illustrations of any kind. It is a conversation between two photographers. I read it in one sitting.
As others have pointed out, this book doesn't tell you what camera to buy, what settings to use, it tells you to learn to use your tools and get out there and shoot. Use what it takes to get the picture you want to take. The authors feel the basis of photography is knowledge and enthusiasm for your subject and finding the correct place to shoot from and the correct time to push the shutter. And did I mention getting out there and shooting? Mr Hurn contends that when good photographers talk about equipment, they mention shoes.
There are other things covered. Travel clothing is mentioned. Keeping notes on photos taken. Having photos well organized so that you can find what you are looking for. If someone asks you for your photo of a tall, white bird with knee socks, you don't have to search every hard drive on your desk.
But the main thing, it talks about the mindset of a photographer. How everything comes through that lens of being a photographer. You see a commercial on TV and think, look how they used light on that coffee.
David Hurn talks about photographing Graham Greene writing every morning and throwing it all away in the afternoon. It was practice writing for when he had an assignment. Mr Greene said he never wrote seriously until his publisher gave him a title. Bill Jay talks about a photographer shooting around his cabin. He asked the photographer what he was shooting as there was nothing there of the photographer's usual subjects. The photographer replied that he shot three cassettes, of 36 frames each, every day to stay in practice.
This is an interesting book I think for every serious photographer who is willing to work hard.
