What you’ll need

Lightroom is designed specifically for photographers working with digital capture images. Lightroom can process JPEG, TIFF, or raw images, but if your camera is capable of capturing raw images, I advise you to shoot in raw mode whenever possible. Lightroom currently supports more than 250 different raw camera formats.

TIP

To see if the raw files from your camera are supported in Lightroom, go to the Adobe Photoshop Web site at http://www.adobe.com/products/photoshop/cameraraw.html.

Those cameras that are capable of capturing raw images using the Digital Negative (DNG) format are also supported by Lightroom. The DNG format offers many benefits: It is a self-contained raw format that can incorporate externally edited XMP metadata (no need for .xmp sidecar files) and, moreover, because DNG is an open standard format, it offers better long term support.

You will need a computer that meets the minimal specifications listed below. Although it is possible to run Lightroom with a minimum of RAM, Lightroom will certainly benefit from having as much RAM as possible, so install at least 2 GB of RAM. Choosing a computer with a fast chip speed will help, of course, and you will also see a further speed improvement if you are able to run Lightroom via a 64-bit operating system. You don’t need much hard disk space to install and run Lightroom, but you will need to give serious consideration as to how you will store all the images in the catalog. Some people can easily shoot 10 GB of images or more in a single day. If you export some of those files as rendered TIFFs or PSDs, your storage requirements can grow considerably in a short amount of time. For more information on computer systems and backup strategies, see Appendix B. Here, though, are the minimum requirements for Mac and PC systems:
