Where Digital Images Come From
iPhoto can work with digital images from a variety of sources.
Digital Camera
Digital cameras are more capable than ever. One key factor that differentiates cameras is resolution: how many pixels of information they store in each image. Even inexpensive digital cameras now provide resolutions of 12 megapixels and up—more than enough to make large prints.
Most digital cameras connect to the Mac’s USB port. Images are usually stored on removable-media cards; you can also transfer images into iPhoto by connecting a media reader to the Mac and inserting the memory card into the reader (page 16).
Scanner
With a scanner, you can create digital images from photographs and other hard-copy originals.
Scanners also connect via USB, although some high-end models connect via FireWire. Film scanners are a bit pricier, but can scan negatives and slides and deliver great image quality (page 138). Save your scanned images in JPEG format, and then add them to iPhoto by dragging their icons into the iPhoto window (page 14).
