Interesting book by Joe Mac, old but relevant, the technology has changed, but the technique is still the same.
If you don’t like Joe Mac then it’s not for you, but for the rest of us, Nikon guys it’s good.
Combines technical content with humour and forthright opinions!
Joe McNally has a deft style of writing that combines technical knowledge with wit, inventive analogies and his often iconoclastic opinions. It's the best (and most readable) account of off-camera flash work that I have seen.
