Executive Summary This Fellowship study explored the use of analogue and digital technologies to create colour surfaces and sound experiences. The research focused on art and design activities that combine traditional analogue techniques (such as drawing or painting) with print and electronic media (from simple LED lighting to large-scale video projections on buildings). The Fellow’s rich and varied self-directed research was centred in Venice, Italy, with visits to France, Sweden, Scotland and the Netherlands to attend large public events such as the Biennale de Venezia and the Edinburgh Festival, and more intimate moments where one-on-one interviews were conducted with renown artists in their studios. -
Depth of Field PDF Only
Depth of Field for Digital Images Robin D. Myers Better Light, Inc. In the days before digital images, before the advent of roll film, photography was accomplished with photosensitive emulsions spread on glass plates. After processing and drying the glass negative, it was contact printed onto photosensitive paper to produce the final print. The size of the final print was the same size as the negative. During this period some of the foundational work into the science of photography was performed. One of the concepts developed was the circle of confusion. Contact prints are usually small enough that they are normally viewed at a distance of approximately 250 millimeters (about 10 inches). At this distance the human eye can resolve a detail that occupies an angle of about 1 arc minute. The eye cannot see a difference between a blurred circle and a sharp edged circle that just fills this small angle at this viewing distance. The diameter of this circle is called the circle of confusion. Converting the diameter of this circle into a size measurement, we get about 0.1 millimeters. If we assume a standard print size of 8 by 10 inches (about 200 mm by 250 mm) and divide this by the circle of confusion then an 8x10 print would represent about 2000x2500 smallest discernible points. If these points are equated to their equivalence in digital pixels, then the resolution of a 8x10 print would be about 2000x2500 pixels or about 250 pixels per inch (100 pixels per centimeter). The circle of confusion used for 4x5 film has traditionally been that of a contact print viewed at the standard 250 mm viewing distance. -
Dof 4.0 – a Depth of Field Calculator
DoF 4.0 – A Depth of Field Calculator Last updated: 8-Mar-2021 Introduction When you focus a camera lens at some distance and take a photograph, the further subjects are from the focus point, the blurrier they look. Depth of field is the range of subject distances that are acceptably sharp. It varies with aperture and focal length, distance at which the lens is focused, and the circle of confusion – a measure of how much blurring is acceptable in a sharp image. The tricky part is defining what acceptable means. Sharpness is not an inherent quality as it depends heavily on the magnification at which an image is viewed. When viewed from the same distance, a smaller version of the same image will look sharper than a larger one. Similarly, an image that looks sharp as a 4x6" print may look decidedly less so at 16x20". All other things being equal, the range of in-focus distances increases with shorter lens focal lengths, smaller apertures, the farther away you focus, and the larger the circle of confusion. Conversely, longer lenses, wider apertures, closer focus, and a smaller circle of confusion make for a narrower depth of field. Sometimes focus blur is undesirable, and sometimes it’s an intentional creative choice. Either way, you need to understand depth of field to achieve predictable results. What is DoF? DoF is an advanced depth of field calculator available for both Windows and Android. What DoF Does Even if your camera has a depth of field preview button, the viewfinder image is just too small to judge critical sharpness. -
Slow Motion Video
Slow Motion Video MediaTek Technology White Paper May 2015 Slow Motion Video Introducing Slow Motion Video MediaTek’s Slow Motion Video technology allows the device user to easily capture, replay, and share a fast moving object any time. Slow Motion Video can record video at a high frame rate such as 120fps, 180fps or higher, playback in slower speed such as 1/2x,1/4x, and 1/16x. And, the user can easily share this slow motion video. High frame rate recording allow users to capture more details and wonderful moments for a fast moving object. Compared with normal camera recording, which only can capture 24fps – 30fps, high frame-rate recording can capture as much as 120,180fps, which allows for more fluent recording. Mediatek provides a whole solution for high frame-rate recording, so that business partners can easily combine their high frame rate camera sensors with Mediatek ICs to provide many new wonderful features. Now VGA@120fps for MT6752, HD@180fps for MT6595 and MT6795 are supported, and higher, such as HD@240fps, will be available on later MediaTek octa-core ICs. Slow Motion Video playback allows user to slow down the playback speed so as to enjoy a fully playback experience. Playing the high frame rate recorded video will bring much more fluent watching experience. But as we all know, the human video processing capability is limited, so humans cannot capture details of a fast moving object if replayed in 1x speed. By using the slow motion playback, the user can not only distinguish each amazing moment but also can enjoy interesting viewing experience. -
Ground-Based Photographic Monitoring

Hall Author Frederick C. Hall is senior plant ecologist, U.S. Department of Agriculture, Forest Service, Pacific Northwest Region, Natural Resources, P.O. Box 3623, Portland, Oregon 97208-3623. Paper prepared in cooperation with the Pacific Northwest Region. Abstract Hall, Frederick C. 2001 Ground-based photographic monitoring. Gen. Tech. Rep. PNW-GTR-503. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 340 p. Land management professionals (foresters, wildlife biologists, range managers, and land managers such as ranchers and forest land owners) often have need to evaluate their management activities. Photographic monitoring is a fast, simple, and effective way to determine if changes made to an area have been successful. Ground-based photo monitoring means using photographs taken at a specific site to monitor conditions or change. It may be divided into two systems: (1) comparison photos, whereby a photograph is used to compare a known condition with field conditions to estimate some parameter of the field condition; and (2) repeat photo- graphs, whereby several pictures are taken of the same tract of ground over time to detect change. Comparison systems deal with fuel loading, herbage utilization, and public reaction to scenery. Repeat photography is discussed in relation to land- scape, remote, and site-specific systems. Critical attributes of repeat photography are (1) maps to find the sampling location and of the photo monitoring layout; (2) documentation of the monitoring system to include purpose, camera and film, w e a t h e r, season, sampling technique, and equipment; and (3) precise replication of photographs. -

Cinematography
CINEMATOGRAPHY ESSENTIAL CONCEPTS • The filmmaker controls the cinematographic qualities of the shot – not only what is filmed but also how it is filmed • Cinematographic qualities involve three factors: 1. the photographic aspects of the shot 2. the framing of the shot 3. the duration of the shot In other words, cinematography is affected by choices in: 1. Photographic aspects of the shot 2. Framing 3. Duration of the shot 1. Photographic image • The study of the photographic image includes: A. Range of tonalities B. Speed of motion C. Perspective 1.A: Tonalities of the photographic image The range of tonalities include: I. Contrast – black & white; color It can be controlled with lighting, filters, film stock, laboratory processing, postproduction II. Exposure – how much light passes through the camera lens Image too dark, underexposed; or too bright, overexposed Exposure can be controlled with filters 1.A. Tonality - cont Tonality can be changed after filming: Tinting – dipping developed film in dye Dark areas remain black & gray; light areas pick up color Toning - dipping during developing of positive print Dark areas colored light area; white/faintly colored 1.A. Tonality - cont • Photochemically – based filmmaking can have the tonality fixed. Done by color timer or grader in the laboratory • Digital grading used today. A scanner converts film to digital files, creating a digital intermediate (DI). DI is adjusted with software and scanned back onto negative 1.B.: Speed of motion • Depends on the relation between the rate at which -

Depth of Field in Photography
Instructor: N. David King Page 1 DEPTH OF FIELD IN PHOTOGRAPHY Handout for Photography Students N. David King, Instructor WWWHAT IS DDDEPTH OF FFFIELD ??? Photographers generally have to deal with one of two main optical issues for any given photograph: Motion (relative to the film plane) and Depth of Field. This handout is about Depth of Field. But what is it? Depth of Field is a major compositional tool used by photographers to direct attention to specific areas of a print or, at the other extreme, to allow the viewer’s eye to travel in focus over the entire print’s surface, as it appears to do in reality. Here are two example images. Depth of Field Examples Shallow Depth of Field Deep Depth of Field using wide aperture using small aperture and close focal distance and greater focal distance Depth of Field in PhotogPhotography:raphy: Student Handout © N. DavDavidid King 2004, Rev 2010 Instructor: N. David King Page 2 SSSURPRISE !!! The first image (the garden flowers on the left) was shot IIITTT’’’S AAALL AN ILLUSION with a wide aperture and is focused on the flower closest to the viewer. The second image (on the right) was shot with a smaller aperture and is focused on a yellow flower near the rear of that group of flowers. Though it looks as if we are really increasing the area that is in focus from the first image to the second, that apparent increase is actually an optical illusion. In the second image there is still only one plane where the lens is critically focused.
