Review answers

1A camera raw file contains unprocessed picture data from a digital camera’s image sensor. Camera raw files give photographers control over interpreting the image data, rather than letting the camera make the adjustments and conversions. When you make adjustments to a camera raw image, Photoshop and Bridge preserve the original camera raw file data. This way, you can edit the image as you desire, export it, and keep the original intact for future use or other adjustments.
2The Adobe Digital Negative (DNG) file format contains the raw image data from a digital camera as well as metadata that defines what the image data means. DNG is an industry-wide standard for camera raw image data that helps photographers manage proprietary camera raw file formats and provides a compatible archival format.
3Red eye occurs when the retinas of a subject’s eyes are reflected by the camera flash. To correct red eye in Adobe Photoshop, zoom in to the subject’s eyes, select the Red Eye tool, and then click the red eyes. The red reflection disappears.
