The reason I love this book is that it's packed with so much info, that I pick up something new every time I read it.
There are many sections in this book, which I believe differentiates it from other wedding publications. For example, I particularly found useful the illustrated complete shooting list, time requirements, cultural variations, group building & the post-production.
I have read a number of wedding photography books recently and this one was far and away the best value for money, the most helpful and inspiring.
I would recommend anyone who wants to become a wedding photographer either professionally or as a keen amateur to buy this book.
