its useful for people to get into photography... not useful for those who are already into it and know the basic.good meh? Browsed it once in Kino like not very useful leh. Just the typical newbie guide to digital photography. There is 101 this kind of books out there in the National library.
imho, i like how they explain aperture... etc but using lots of pictures that are very easy to understand, unlike some books that are just plain load of text.
