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. -

‘An evaluation of Flickr’s distributed classification system, from the perspective of its members, and as an image retrieval tool in comparison with a controlled vocabulary’ A dissertation submitted for an MA in: Information Services Management London Metropolitan University September 2008 By Samuel Piker Abstract The profusion of digital images made available online presents a new challenge for image indexing. Images have always been problematic to describe and catalogue due to lack of inherent textual data and ambiguity of meaning. Because professionally- applied metadata is not practical for most open, web-based collections a solution has been sought in the form of tags, simple keywords that can be attached to an image by any web user. Together tags form a flat structure known as distributed classification, or more popularly as a folksonomy. This research follows the debate surrounding folksonomies and aims to fill the gaps in understanding of why people tag and how effective they find them for searching, using the photo-sharing website Flickr as the focus. Open-ended questionnaires were sent out to members of the site who use tags, with the opportunity to post comments to an online discussion space. The other key gap identified in the literature is a systematic comparison between a tag-based system and a more traditional controlled vocabulary, to test out the claims made regarding tagging’s suitability for searching and browsing. For this purpose Flickr has been compared with Getty Images using a series of test themes. The small number of people who replied to the questionnaire gave detailed answers that confirmed several of the assertions made about tags: they are accepted despite their flaws (sloppiness and potential for inaccuracy) because they serve their purpose to a satisfactory level. -

Workshop Lesson Plan
Workshop Lesson Plan The emphasis is on practical hands-on learning, designed to advance the students’ knowledge and comprehension - the approach will be intensive but fun. This course is designed as a step by step training programme for students to master not only the language of light and its behavior, but to learn to see it, move it and most importantly control it. In addition, we look at creating our own ‘visual grammar’ and style from one’s own perspective. Key attributes and themes - Creativity - Leadership - Team Working - Life Enrichment - Educational resource - Personal Development - Self-expression Lesson Plans Workshop 1: Storyboarding and Fine Art ‘Lifestyle’ Photography Practical introduction of photography in a ‘fine art’ context, delving into the areas of: · The thought process for interior photography · The options for hand held shooting · How to setup the camera when shooting hand held · Why shooting on a tripod offers lots of benefits · Why shooting manually can give more consistent results · Seeing and coping with high contrast lighting Workshop 2: The World around us – Landscapes and Panoramas Painting with light and long exposures. Choosing lenses and filters Exploring more two distinctive areas of landscape photography: Impressionistic - employs photographic techniques that result in images that have vague or elusive qualities. They are less tangible and more unreal, while still retaining their values that make them landscape pictures. The viewer is given the impression of a landscape rather than the clear reality of one. Abstract - referred to as the ‘graphic style’, since the components of scenery are treated by the photographer as graphic elements, arranged for their compositional values. -

Although the ,roIes of intuition and hpreyisualization" are debated:the mechanical nature of mass media and the commbn link of realism probably make previsualizationmore important for the designer and photojournalist. The complex relationship betweenform and content that results when photographsare printed in the mass media depend%upon cropping as well,as upon Jines and shapes. Framing is nothiv more than the lines that-mark the borderbetween artifact and environmental space or image and border. Linesare also the primary tool of previspalization, andnecessary in the creation of three dimensional effects. As physiscal events, linesrepresent a balancing of compositional forces, and theycan also be perceived temporally. Although photojournai'Lsts discover lines while designers create them, students in both disciplines can benefit by. -

LS Landscape/Seascape/Cityscape SL Still Life PO Portrait FL Floral
Photography Show - Category Code Definitions LS Landscape/Seascape/Cityscape Landscape photography shows spaces within the world, sometimes vast and unending, but other times microscopic. Landscape photographs typically capture the presence of nature but can also focus on man-made features or disturbances of landscapes. A seascape is a photograph that depicts the sea, or an example of marine art. The word has also come to mean a view of the sea itself, and when applied in geographical context, refers to locations possessing a good view of the sea. A cityscape is a city viewed as a scene; an artistic representation of a city; an urban environment. A cityscape (urban landscape) is a photograph of the physical aspects of a city or urban area. It is the urban equivalent of a landscape. Townscape is roughly synonymous with cityscape, and it implies the same difference in size and density implicit in the difference between the words city and town. SL Still Life Still life photography is the depiction of inanimate subject matter, most typically a small grouping of objects. Still life photography, more so than other types of photography, such as landscape or portraiture, gives the photographer more leeway in the arrangement of design elements within a composition. Still life photography is a demanding art, one in which the photographers are expected to be able to form their work with a refined sense of lighting, coupled with compositional skills. The still life photographer makes pictures rather than takes them. PO Portrait Portrait photography or portraiture in photography is a photograph of a person or group of people that captures the personality of the subject by using effective lighting, backdrops, and poses.
