After searching for information on photography books, I decided to buy this book. I bought it from opentrolley online book store for S$ 38.
The book described what is exposure, photographic triangle (aperture, shutter speed, and sensitivity) and the effects on exposure. It mentioned about the differences between correct exposure and creative exposure, and why people still want to read the book while the camera has already provided them with "correct" exposure in P mode. The book also described about frontlight, backlight and sidelight. A lot of techniques that are useful for photographers are also mentioned here, such as 18% reflectance and grey card, blue sky brothers and mr green jeans, panning, and few filters that are commonly used by photographers. Overall it was enjoyable book to read.
