The general wisdom is wrong. Using a different TYPE of camera is a challenge which some professional and non-professional photographers may enjoy and find stimulating. The book is not all about 'taking photographs,' but about ways of enjoying one's photography,and developing new ideas.
Lee does not simply write "Take a Break." He gives sound advice on equipment to be taken,and advice on making the most of one's photography when away.
Each page is carefully written, as is all of Lee's published work: the book is crammed full of of detailed advice and information.
A thoroughly good buy whether one is a beginner or experienced professional.
