If photographing children and moms-to-be is your calling, then you need to read Mimika Cooney's book, Boutique Baby Photography: The Digital Photographer's Guide to Success in Maternity and Baby Portraiture. This all-encompassing guide tells you everything you need to know from the business end of running a studio through making successful images. Perhaps the most valuable aspect of this the book, however, is that it teaches you how to keep clients coming back from the first pregnancy throughout childhood and beyond.
