When I exhibit my best prints to an appreciative audience, I feel akin to the Wizard of Oz. Dorothy and her companions were supposed to see only that majestic head with the spouting flames and smoke and to ignore the little man behind the curtain pulling the levers. If I am successful as a printmaker, my viewers look at my work with joy at its beauty. They don’t note the tricks, manipulations, and outright visual deceptions that go into making a print that inspires awe. I’ve been doing serious photography for 37 of my 51 years. By the time I’d taught myself how to make dye transfer prints from my color negatives, back in 1975, I thought I was a pretty hot printer. Now I know I wasn’t half as good as I thought. Twenty years hence, I’ll look back and again be embarrassed by how much I thought I knew. Fine printmaking is an everlasting learning experience for all of us. When I began my life in the darkroom, prints were still universally made on fiber- based paper, C-22 processing was standard for color negatives, E-3 was still common for some transparency films, and Cibachrome (now Ilfochrome) had yet to take its place in the darkroom community. Many materials available to the typical darkroom worker have improved immensely. We have also seen changes for the worse. Dye transfer printing was killed by Kodak in 1993. Although a few other printers and I still make these finest of prints, our supplies are limited and our prospects for ever getting more are uncertain. Although materials have changed over the years, I’ve found the principles of fine printing haven’t. Master printmaking is a discipline requiring both talent and knowledge and no small amount of legerdemain. The discipline doesn’t come from the specific printing materials one uses or whether one prints black and white (B&W) or color or even whether one works in the darkroom or at a computer. The methods of fine printmaking are rooted in our own perceptions, the ways the human vision system sees the world, the ways that photographic materials see it differently, and immutable laws of optics and nature. This book is not a primer on photographic printing. I’m not going to tell you how to develop a roll of film or process a print, and I assume you have a working knowledge of photography. Its purpose is to teach photographers the refinements of photographic xi printmaking, to take them from making those merely competent prints to making excellent ones. This book brings together disparate fields of knowledge, distilled from my three decades of learning and experience in color and B&W photographic printing. In learning about both a human’s and a film’s perception of the world, you’ll pick up some informational tidbits about color theory, the nature of the human visual system, information and measurement theory, neurophysiology, and other arcane topics. Still, most of this book is about tools, techniques, and darkroom procedures; I intend this to be a practical book, not one of difficult-to-apply theory. Even novice printers can learn from this book. Some of what I say is pretty fundamental, but it is information most photographers don’t know and won’t find in the average photography book. I intend this book to be useful to anyone making color or B&W prints, including people working with a computer instead of an enlarger. One can’t entirely fix an ineptly photographed image on a computer any more than one can fix it in the darkroom. If one doesn’t understand the principles of good printmaking or have a real understanding of what the viewers truly see when they look at a print, one is no more likely to produce a truly fine print with the aid of a computer than with an enlarger. The tools change, but the principles don’t. Results speak for themselves. You can see several dozen of my finest photographs on your computer. I’ve created a Web site called Ctein’s Online Gallery (http:// www.plaidworks.com/ctein/), which contains very high-quality screen images of some of my dye transfer photographs. My site also includes a smattering of articles by me, including a lengthy one on dye transfer printing, and hints and tips for viewing images on your computer with the best possible fidelity. You can also reach me through my e-mail address ([email protected]). I do enjoy hearing from my fans! ACKNOWLEDGMENTS So many people have helped me over the years that there is no way I can thank them all. I feel a special appreciation must go to Frank McLaughlin and Bob Nadler; their support and sage advice helped make me the fine printmaker and photographic writer I am today. I am grateful to Tammy Harvey, whose very hard work made this book possible. I am equally grateful to Jodie McCune, whose equally hard work made it real. For everything, from suggesting the structure of this book to suggesting its title, I owe an enormous debt to Laurie Toby Edison, a fine photographer and my finest friend, now and always.

  • Breaking Down the “Cosine Fourth Power Law”
    Breaking Down The “Cosine Fourth Power Law” By Ronian Siew, inopticalsolutions.com Why are the corners of the field of view in the image captured by a camera lens usually darker than the center? For one thing, camera lenses by design often introduce “vignetting” into the image, which is the deliberate clipping of rays at the corners of the field of view in order to cut away excessive lens aberrations. But, it is also known that corner areas in an image can get dark even without vignetting, due in part to the so-called “cosine fourth power law.” 1 According to this “law,” when a lens projects the image of a uniform source onto a screen, in the absence of vignetting, the illumination flux density (i.e., the optical power per unit area) across the screen from the center to the edge varies according to the fourth power of the cosine of the angle between the optic axis and the oblique ray striking the screen. Actually, optical designers know this “law” does not apply generally to all lens conditions.2 – 10 Fundamental principles of optical radiative flux transfer in lens systems allow one to tune the illumination distribution across the image by varying lens design characteristics. In this article, we take a tour into the fascinating physics governing the illumination of images in lens systems. Relative Illumination In Lens Systems In lens design, one characterizes the illumination distribution across the screen where the image resides in terms of a quantity known as the lens’ relative illumination — the ratio of the irradiance (i.e., the power per unit area) at any off-axis position of the image to the irradiance at the center of the image.

Rich Associate Professor of Art History Thesis Supervisor Sarah K. Rich Associate Professor of Art History Honors Adviser Nancy E. Locke Associate Professor of Art History Faculty Reader * Electronic approvals are on file. i ABSTRACT This thesis looks into the body of art works created by Wolfgang Tillmans from the early 1980s to the present, with a focus on the transforming quality of the photographic medium. The essay first investigates the early clashing of mediums in the artist’s work: the photo printer, digital camera, and film in the photograph surface. Then, the essay delves into a longer history of abstract photography that relates to modernist notions of medium specificity. The third chapter deals with the issue of body in a double fold: the body of the art work, and the body of the artist. The fourth chapter introduces a systematic view on Tillmans’ thirty-years-long oeuvre, connecting the motif of astronomy with a distinct world view hidden behind Tillmans photographs. ii TABLE OF CONTENTS Acknowledgements....................................................................................................................... iii List of Figures..............................................................................................................................

  • Sample Manuscript Showing Specifications and Style
    Information capacity: a measure of potential image quality of a digital camera Frédéric Cao 1, Frédéric Guichard, Hervé Hornung DxO Labs, 3 rue Nationale, 92100 Boulogne Billancourt, FRANCE ABSTRACT The aim of the paper is to define an objective measurement for evaluating the performance of a digital camera. The challenge is to mix different flaws involving geometry (as distortion or lateral chromatic aberrations), light (as luminance and color shading), or statistical phenomena (as noise). We introduce the concept of information capacity that accounts for all the main defects than can be observed in digital images, and that can be due either to the optics or to the sensor. The information capacity describes the potential of the camera to produce good images. In particular, digital processing can correct some flaws (like distortion). Our definition of information takes possible correction into account and the fact that processing can neither retrieve lost information nor create some. This paper extends some of our previous work where the information capacity was only defined for RAW sensors. The concept is extended for cameras with optical defects as distortion, lateral and longitudinal chromatic aberration or lens shading. Keywords: digital photography, image quality evaluation, optical aberration, information capacity, camera performance database 1. INTRODUCTION The evaluation of a digital camera is a key factor for customers, whether they are vendors or final customers. It relies on many different factors as the presence or not of some functionalities, ergonomic, price, or image quality. Each separate criterion is itself quite complex to evaluate, and depends on many different factors. The case of image quality is a good illustration of this topic.

  • Inkjet Photo Prints: Here to Stay
    Inkjet Photo Prints: Here to Stay Dr. Nils Miller, Hewlett-Packard Company June 2004 Executive Summary A recent report from the Photo Marketing Association states, “2003 was a pivotal year for the industry, with digital cameras outselling traditional cameras for the first time ever… This gap will widen in 20041”… As more customers move to digital cameras, more are also choosing inkjet photo printers thanks to significant advances in image quality and convenience. The increasing numbers of customers who are using digital photography would indicate that they are very satisfied with digital cameras and inkjet photo printing and have indeed answered yes to the question: “Do inkjet photo prints have image quality equal to (or better than) traditional silver-halide photo prints?” One question remains, however, for customers who currently use inkjet or are considering inkjet in the future to print their valuable photos: “Will inkjet photo prints last as long as traditional silver-halide photo prints?” Estimates of the life of photo prints are based on whether the prints will be displayed or stored. In all likelihood, only a small portion of photo prints are actually displayed and subjected to regular illumination. Displayed prints are among the most treasured, and customers need to feel confident that they can enjoy these images for a lifetime. This paper will address the display permanence of inkjet photo prints including relevant results of HP internal tests and HP’s current line of photo print media and inks. Inherited Silver-Halide Permanence Standards The science of predicting the display permanence of silver-halide photo prints is quite mature.

  • FILM FORMATS ------8 Mm Film Is a Motion Picture Film Format in Which the Filmstrip Is Eight Millimeters Wide
    FILM FORMATS ------------------------------------------------------------------------------------------------------------ 8 mm film is a motion picture film format in which the filmstrip is eight millimeters wide. It exists in two main versions: regular or standard 8 mm and Super 8. There are also two other varieties of Super 8 which require different cameras but which produce a final film with the same dimensions. ------------------------------------------------------------------------------------------------------------ Standard 8 The standard 8 mm film format was developed by the Eastman Kodak company during the Great Depression and released on the market in 1932 to create a home movie format less expensive than 16 mm. The film spools actually contain a 16 mm film with twice as many perforations along each edge than normal 16 mm film, which is only exposed along half of its width. When the film reaches its end in the takeup spool, the camera is opened and the spools in the camera are flipped and swapped (the design of the spool hole ensures that this happens properly) and the same film is exposed along the side of the film left unexposed on the first loading. During processing, the film is split down the middle, resulting in two lengths of 8 mm film, each with a single row of perforations along one edge, so fitting four times as many frames in the same amount of 16 mm film. Because the spool was reversed after filming on one side to allow filming on the other side the format was sometime called Double 8. The framesize of 8 mm is 4,8 x 3,5 mm and 1 m film contains 264 pictures.
