How does the Zone System Apply to Digital Photography? Why is Photographic Technique So Important? If the Zone System is So Important, How were Good Photographs  Taken without it? Isn’t the Zone System Useful Only with View Cameras? Do I need a Spot Meter to Use the Zone System? Camera Manufacturers Give the Impression that Taking Good Pictures can be  Simple and Automatic Is the Zone System Outdated? How does the Zone System Apply to the Use of an Electronic Flash? Can the Zone System be Used with Color Film?

all elements in a digital imaging workflow for the purpose of ensuring that the final print or other output matches the image represented on the computer monitor as closely as possible Colorsync  A color management system introduced by Apple Computer Co Contraction  The decrease in negative contrast brought about by using a development time that is less than Normal Development Contraction is symbolized by N –, followed by the number of zones by which you want to decrease the contrast For example, N – means decrease the development time below Normal Development enough to reduce a Zone IX negative density to a density equivalent to Zone VII Contraction is also known as “compaction.” Contrast  Subject Contrast refers to the relative difference between the amount of light reflected by the “highlights,” or bright areas, of the subject and the “shadows,” or darker areas This difference is measured with a reflected-light meter Negative Contrast refers to the relative difference between the “shadow,” or thinner, areas of the negative and the “highlight,” or more dense, areas Print Contrast (also called “tonal separation”) is the ability of the film and printing paper to render a visual distinction between close tonal values Print contrast increases when a negative is printed on higher grades of paper Density  “Density” is technically a scientific term used to indicate the relative opacity of a negative as measured with a densitometer The term is commonly understood to mean the relative thickness of silver in the negative DPI (dots per inch)  A measurement of the resolution of a digital photo or digital device, including digital cameras and printers The higher the number, the greater the resolution Drivers  Software associated with digital scanners and printers that controls the functioning and coordination of the device with all other elements of the workflow Dynamic Range  The term used to define the total range of tonal values in a digital image Also referred to as “contrast.” Expansion  The increase in negative density brought about by developing the negative longer than Normal Development Expansions are symbolized by N+, followed by the number of zones by which you want to increase the contrast For example, N + means to increase the negative’s development time above Normal Development enough to raise a Zone VI negative density to a Zone VIII density 342  |  Appendix Y  Glossary Fall  The term used to indicate the position of any subject's meter reading on the Zone Scale after another meter reading has been placed on a different zone For example, when the contrast of the subject is Normal, the meter reading for the highlight will fall on Zone VII when the meter reading for the shadow is placed on Zone III Gamut  The total range of colors that a digital device can reproduce Histogram  A graphic representation of the range of tones from dark to light in a digital photograph Important Highlight  The area of the subject that you want to appear in the final print as a fully textured and detailed light gray tone In most cases, this area will be previsualized as Zone VII Light clothing, concrete, and fully textured white objects are typical Important Highlight Area subjects Important Shadow  The area of the scene that you want to appear in the final print as a fully detailed dark value This need not be an actual shadow In most cases, the Important Shadow Area is previsualized as Zone III Dark clothing, brown hair, and green foliage are common Important Shadow Area subjects Incident Light  The light that falls on the subject from the light source; measured with an incidentlight meter Indicating Arrow  The arrow or pointer on a handheld light meter that is matched with the indicated meter reading to calculate the meter's recommended exposure The meter number indicated by this arrow is automatically placed on Zone V Interpolation  A mathematical method of creating missing image data to increase the file size and/ or dimensions of an image Inverse Square Law  A physical law stating that intensity of brightness radiating from a light source is inversely proportional to the square of the distance from the source; so an object (of the same size) twice as far away receives only one-quarter the illumination For photographers working in a lighting studio, this means that if you double the distance between a subject and light source, the illumination on the subject will be decreased by four times (two stops) Inversely, if you halve the distance between a subject and light source, the illumination will be increased by four times (again two stops) JPEG  A standard for compressing image data developed by the Joint Photographic Experts Group LCD (Liquid Crystal Display)  A low-power monitor often used on the top and/or rear of a digital camera to display settings or the photo itself Glossary  |  343 Megabyte (MB)  A measurement of data storage equal to 1,024 kilobytes (KB) Megapixel  Equal to one million pixels Neutral Gray Card  A middle gray (18 percent) card designed for calibrating exposure meters and to serve as a visual reference for color reproduction Also known as a “Zone V card.” Noise  Random patterns of either color or brightness that appear in the shadow areas of digital images with higher ISO settings (400 and above) Normal  a Subject Contrast is said to be Normal when the meter readings of the Important Shadow and the Important Highlight fall on Zone III and Zone VII, respectively b Negative Contrast is considered Normal when the negative prints well on a Normal grade of paper, usually paper grade or variable-contrast filter c Normal Development is the amount of development for a given film and developer that will produce contrast in the negative that is equal to the contrast of the subject Normal Development is symbolized by N Pixel  Pixels or picture elements are the smallest components of digital images Digital camera and monitor pixels are the physical units that capture and display digital image data, respectively Image pixels are the individual “tiles” of color or tone that make up the visible image on a monitor Placement  The act of relating any single meter reading to a zone on the Zone Scale through controlled exposure For example, to place a shadow reading on Zone III, you first meter that area with a reflected-light meter and then stop down two stops from the meter’s recommended exposure Posterization  See “Banding.” Previsualization  (also visualization)—The act of mentally picturing a photographic subject in terms of the finished print Profile  A small data file that describes the color idiosyncrasies of each element of a color-managed digital workflow, including the monitor and printer, for the purpose of providing coordination of color rendition from one end of the process to the other Raster Image Processor (RIP)  A raster image processor or “rip” is a highly integrated color management, page layout, and ink-handling system that provides the highest quality results from inkjet printers Rasterization  See “Bitmapped.” 344  |  Appendix Y  Glossary Raw Formats  The unprocessed black-and-white data from a digital image sensor before it has been converted or Tone Mapped into a color format that can be edited with an application like Adobe’s Camera Raw utility Reflected Light  The light that is reflected from the scene to the camera and meter; measured with a reflected-light meter Resolution  For analog photography, the term is used to describe a film's capability to record fine detail For film, good resolution is a function of sharp focus, fine grain, good contrast, and minimum exposure and development For digital image files, good resolution is achieved through a combination of increasing the number of pixels per inch in your image and assigning an appropriately high bit depth to each pixel Tagging  The process of attaching a profile to a digital image to allow it to be rendered accurately on other color-managed systems Textural Scale  The range of five textured zones from Zone III to Zone VII Tonal Range  The difference between the whitest white and the blackest black in a photographic print Tonal Separation  See “Print Contrast” under “Contrast.” Tone  The shades of gray, black, and white in a photographic print Tone Mapping  The process of converting a digital image from its raw, linear state to a format that more closely resembles a familiar nonlinear distribution of tones Value  The light and dark areas of a photographic subject, negative, or print Vector-Based Images  A graphic image whose visual characteristics are created mathematically by an application like Adobe Illustrator As opposed to a digital image composed of numerous individual picture elements or pixels Visualization  See “Previsualization.” Zone  The basic unit of photographic previsualization and contrast measurement a Any one of 10 symbolic tones arranged in order from black to white This 10-step scale is called the “Zone Scale.” Each zone represents a small range of tones that can be found in both the final print and the original scene b A unit of photographic measurement equivalent to all other photographic controls according to a ratio of to Index A Acufine developer, 282 Adams, Ansel, 2, 111, 121, 130, 193, 300,
