Not sure who this book is for, a list of do's and don't. No real explaination of principles. Contradictory information, which is not incorrect but is not a helpful learning experience. Disorganised approach. Perhaps if you are an expert graphic designer you could flick through an confirm you already knew it!
Bought to protect lens and enhance outdoor photos. Perfect fit, looks like quality product, no issue with camera operation - super macro to zoom - Lens cap fits fine adds about 2mm to lens. Very highly recommend at price.
