(p.129) An image's ________ reflects the lighting conditions under which it was captured.

(p.138) The Joint Photographic ________ Group (JPEG) image format is commonly used to display photographs and other continuous-tone RGB images on the web.
(p.138) The JPEG image format retains all color information in an image but compresses file size by selectively ________ data.
(p.138) The greater the compression in a JPEG file, the ________ the image quality.
greater
lower
(p.138) The ________ format is the Photoshop native file format.
(p.139) ________ is the ratio between dark and bright regions of an image.

(p.144 & 145) You use the ________ tool to lighten areas of an image.
(p.145) Use the Sponge tool to increase ________.
(p.147) Save your master photos in PSD, TIFF, or DNG format, not in JPEG. Each time a JPEG is re-edited and saved, compression is reapplied and the image quality ________.
(p.148) Apply the ________ filter to give an image a smooth appearance.
(p.149) The Shadow/Highlight command is suitable for correcting photos whose subjects are silhouetted against strong ________ or are washed out from being too close to the camera flash.
(p.149) The Shadow/Highlight command is also useful for pulling details from the ________ in an image that is otherwise well-lit.
(p.151) Red eye occurs when the retinas of a subject's eyes are reflected by the camera ________.
(p.151) Red eye commonly occurs in photographs of a subject in a ________ place, because the subject's irises are wide open.
(p.151) Image ________ is random, extraneous pixels that aren't part of the image detail.
(p.151) One type of image noise, ________ noise, is grayscale data that makes an image look grainy or patchy.
(p.151) The other type of image noise, ________ noise, is usually visible as colored artifacts in the image.
(p.153) The Lens Correction filter fixes ________ distortion, a lens defect that causes straight lines to bow out toward the edges of the image.
(p.153) The lens flaw known as ________ aberration appears as a color fringe along the edges of image objects.
(p.153) A camera lens flaw called ________ occurs when the edges of an image, especially the corners, are darker than the center.
(p.156) If you want an entire image to be in focus, take two photos—one with the background in focus and one with the foreground in focus— and then merge the two in Photoshop. This is called adding ________.
