Chapter 5. Creating a Color-Managed Work... > Importing RAW Digital Images

Importing RAW Digital Images

When a digital camera saves a JPEG or TIFF file, it performs a variety of processing tasks, such as tonal and color adjustments, sharpening, and compression, and converts the file from raw sensor data to a bitmap file. These modifications cannot be undone, and they can remove details from the image. As an alternative, many digital cameras support a file format known as RAW that contains unmodified data captured by the camera's sensor, which can then be converted to a bitmap format on the PC. This enables the photographer to decide how the file is converted and what modifications are made during the conversion process.

Each camera manufacturer has its own RAW file format and application to convert the files to more bitmap formats for use in design and imaging applications. The conversion is performed on the computer, where the photographer can adjust the image an unlimited number of times without the risk of permanently losing data. In addition to camera manufacturer's RAW converters, there are several third-party solutions, including the Adobe Camera RAW feature in Photoshop.
