Method for Testing Photographic Quality of Aeriql Negatives
- ---------------------------- METHOD FOR TESTING PHOTOGRAPHIC QUALITY OF AERIAL NEGATIVES James Marvin Cultice Agricultural Adjustment Administration HE inspection of aerial photographic materials as executed by the Agri T cultural Adjustment Administration may be divided into two rather sharply divided classes of work, namely, the cartographic or engineering inspection in volving crab, tilt, overlap, etc., as determined from contact prints, and the photographic inspection of the negatives to determine their acceptability for each particular contrast based on the Standard Government Specifications for Aerial Photography and the Invitation to Bidders. Photographic inspection is a function of the centralized Aerial Photographic Laboratories. These are two in number, serving the eastern portion of the country from Washington, and the western portion from Salt Lake City. A pre liminary part of the inspection may include generally all physical defects such as stains, abrasions, dirt and blemishes of any kind. To elaborate, the Washington Laboratory procedure for film inspection requires the notation of "chemical stains, blemishes, uneven spots, air bells, light or chemical fog, streaks, tears, holes, finger marks, dirt on the back or on the emulsion side of the film, emulsion peels, kinks, unexposed spots, heat buckles, exposure overlaps and unspliced sections." Of course there are many others, but these are mentioned as typical. Such deficiencies can easily be noted and application of a high degree of tech nical judgment is not so necessary. However, in regard to the contrast range, tone value, and definition the inspector is faced with difficult problems. It is obvious that true contrast range or gamma value is directly related to the photographed terrain when all other elements are considered as controlled. -
Grafika Rastrowa I Wektorowa
GRAFIKA RASTROWA I WEKTOROWA Grafikę komputerową, w dużym uproszczeniu, można podzielić na dwa rodzaje: 1) grafikę rastrową, zwaną też bitmapową, pikselową, punktową 2) grafikę wektorową zwaną obiektową. Grafika rastrowa – obraz budowany jest z prostokątnej siatki punktów (pikseli). Skalowanie rysunków bitmapowych powoduje najczęściej utratę jakości. Grafika ta ma największe zastosowanie w fotografice cyfrowej. Popularne formaty to: BMP, JPG, TIFF, PNG GIF, PCX, PNG, RAW Znane edytory graficzne: Paint, Photoshop, Gimp. Grafika wektorowa – stosuje obiekty graficzne zwane prymitywami takie jak: punkty, linie, krzywe opisane parametrami matematycznymi. Podstawową zaletą tej grafiki jest bezstratna zmian rozmiarów obrazów bez zniekształceń. Popularne formaty to: SVG, CDR, EPS, WMF - cilparty Znane edytory graficzne: Corel Draw, Sodipodi, Inscape, Adobe Ilustrator, 3DS LISTA PROGRAMÓW DO GRAFIKI BITMAPOWEJ Darmowe: CinePaint , DigiKam , GIMP , GimPhoto , GIMPshop , GNU Paint , GrafX2 , GraphicsMagick , ImageJ , ImageMagick , KolourPaint , Krita , LiveQuartz , MyPaint , Pencil , Pinta , Pixen , Rawstudio , RawTherapee , Seashore , Shotwell , Tile Studio , Tux Paint , UFRaw , XPaint , ArtRage Starter Edition , Artweaver , Brush Strokes Image Editor , Chasys Draw IES , FastStone Image Viewer , Fatpaint , Fotografix , IrfanView , Paint.NET , Picasa , Picnik , Pixia , Project Dogwaffle , TwistedBrush Open Studio , Xnview Płatne: Ability Photopaint, ACD Canvas, Adobe Fireworks, Adobe Photoshop, Adobe Photoshop Lightroom, Adobe Photoshop Elements, -
Openraw.Org Releases Initial Results of 2006 RAW Survey: Over
4/25/2006 For Immediate Release: OpenRAW.org Releases Initial Results of 2006 RAW Survey: Over 19,000 Photographers and Imaging Professionals Provide Data on their Experiences, Preferences, and Concerns regarding RAW Imaging Technology Will the digital camera you buy tomorrow fairly serve the future of photography? Are today’s camera manufacturers making decisions that may adversely affect the preservation of photographic works for future generations? More than 19,000 digital photographers and preservationists from around the world have now weighed in with opinions on RAW imaging technology, a concept that many compare to a “digital negative.” The OpenRAW initiative (http://www.OpenRAW.org/) is a one-year-old international organization representing the interests of photographers and digital imaging practitioners. From January 31 to March 15, 2006, OpenRAW conducted an international online survey (http://www.OpenRAW.org/survey/) designed to give photographers and other interested parties a voice in the further development of RAW imaging technology. The response was outstanding. During the six-week 2006 RAW Survey, over 19,000 individuals – professional photographers, dedicated amateurs, and other imaging specialists – answered all 25 of the survey’s targeted questions. The average respondent had 19.5 years’ experience in photography. Although RAW imaging technology is routinely discussed in photography forums, until now no systematic information had been gathered about the experiences, requirements, preferences, and concerns of users of digital images regarding RAW technology and its future. At the same time, many photographers and archivists believe that camera manufacturers are making important decisions about RAW image technology with little or no input from the people who buy and use their equipment, or who are involved in the preservation of photographic works. -
Black-And-White Tone Targeting ||
C HAPTER Black-and-White Tone Targeting || OBJECTIVES After completing this chapter you will be able to: ■ define and explain the purposes of tone targeting and tone correction. ■ describe and utilize the systems used to measure tones and tonal range in photographs. ■ convert a measurement taken in one tone-measuring system to another system’s measurement units. ■ use Photoshop’s tools to measure the tones and tonal range in a photograph. ■ explain the variables in printing processes that impact tone targeting. ■ use Photoshop’s tools to perform tone targeting. ■ use Photoshop’s tools to compensate for dot gain. ■ automate the tone targeting process using the Actions palette. ■ improve poor originals through the use of tone targeting. ■ perform tone targeting and correction on an image to be reproduced by a specified printing process. | 73 74 | C HAPTER TWO || ■ tone correction Although Photoshop has tremendous power to improve color ■ tone targeting photographs, the vast majority of printed photographs are still reproduced in black-and-white. Photoshop has several features that will allow you to vastly improve the appearance of printed black-and-white photographs. For example, using Photoshop you can make photographs appear lighter or darker and compensate for the changes that are caused by inherent attributes of varying printing processes. Tone refers to the darkness or lightness of areas within a black-and-white photograph. The process of making photographs appear more pleasing by lightening or darkening particular tones is called tone correction; the process of compensating for changes that are caused by inherent attributes of varying printing processes is called tone targeting.
