Worldwide, over 50 billion digital photos were taken in 2007, and over 11 percent of Americans (including me!) have accumulated more than 10,000 digital photos. The ease of taking digital photos has caused the popularity of photography to skyrocket, but that doesn't mean everything is easier than it was with film cameras. Whether it's picking the right digital camera for your needs, managing your massive photo collection, or getting the most out of iPhoto, we have three just-updated ebooks that can help: "iPhoto '08: Visual QuickStart Guide," "Take Control of Buying a Digital Camera," and "Macworld Digital Photography Superguide." They're available separately, bundled together at significant discounts, and as free or discounted upgrades for existing owners.

• "iPhoto '08: Visual QuickStart Guide" is the sixth edition of my thorough set of step-by-step instructions for every aspect of using iPhoto '08. In 220 pages, the book covers getting started, importing and managing photos, organizing and editing photos, creating slideshows and Web galleries, printing photos in many different ways, sharing photos with other people, and troubleshooting. A pair of appendices explain important photo concepts and provide key tips for taking better photos.

• "Take Control of Buying a Digital Camera" version 3.1 helps you sort out the latest digital camera trends and marketing jargon in order to find a camera that matches your budget, needs, and style, whether you want an inexpensive snapshot camera or a professional digital SLR camera system.
