There are two sides to this book, one which works very well, and one that seems out of place. The book is at its best providing advice for (aspiring) professionals on good business practice and on the 'must have' shots from any wedding. It's interesting that this last item has changed little from one I read 25 years ago, before I shot my first wedding.
Unfortunately, this valuable information is interspersed with much more basic facts about the craft and technicalities of photography as a whole. The author spends more of the book talking about correct exposure and the reciprocal relationship between aperture and shutter speed than I feel is necessary. My - probably old-fashioned - view is that anyone seriously considering a career taking wedding pictures should have long ago mastered the basics. Given the pressure of capturing the most memorable day of most peoples' lives, knowing how your kit works and that a touch of overexposure will keep a white wedding dress from looking grey, should be second nature and require little or no concious thought.
This basic information is also at odds with the advice to buy pro-standard kit and plenty of it, to ensure you're covered against disasters and prepared for any photo opportunities. We've all seen people with 'all the gear but no idea', and it would take a brave novice to invest the amount of money the author suggests before identifying if they have the necessary talent to pursue a career as a wedding snapper.
The book is well illustrated, though the quality of the printing doesn't do justice to some of the images, which themselves vary in appeal from stunning and original to pretty good but clichéd. As you'd expect from a wedding photographer-turned-author, Kenny Kim has used his own pictures throughout the book, so the same brides and grooms appear several times, which helps to tell the story of their wedding days.
In fact, one addition I'd suggest for future editions would be the inclusion - perhaps as an appendix - of a single set of wedding pictures, displayed in chronological order, as they would be presented to the bride and groom. I'd also appreciate a greater understanding of the business side: how to price your services, more marketing tips and the nature of the contracts with second shooters that Kenny mentions only in passing.
The layout of the book is clear, with information set out into well-defined chapters, but there's too much requirement for the reader to flip pages to find the pictures to which the text refers. And, while the exposure details of each shot are given in the caption, there is no indication of lens type or focal length used.
