Abstract:
Biometric portrait as one of the most important means of identifying requirements through strict definition of dimensional relationships, preservation of realistic information about all technical characteristics of the photographic image, so that all biometric values can be digitized and used in recognition. The great variety and accessibility of applications for digital processing of digital record of a photographic image has enabled a visually convincing display of a forged photograph that leaves a different impression on the viewer and transmits a different, that is, a forged message. Due to the need to prove the authenticity of the digital record of the photographic image, methods have been developed for the analysis of the record that can detect deviations from the real record even when there are no visual signs of processing the photographic image. Not all analysis techniques can detect certain methods of photo manipulation, so multiple digital photography detection and analysis techniques need to be applied. In order to prove its authenticity, the scientific paper deals with methods for analysis and detection of forgery of digital photography with respect to the digital record and the structure of JPEG format.

Abstract:
Computers and photography has had a long and complicated relationship throughout the years. As image processing and manipulating capabilities advanced on the computer front, photography re-birthed itself with digital cameras and digital imaging techniques. Development of interconnected social sharing networks like Instagram and Twitter feeds the photographers’/users’ thirst to show off their momentaneous “been there/seen that – capture the moment/share the moment” instincts. One other unlikely front emerged as an image processing power of the consumer electronics improved is “video game worlds” in which telematic travellers may shoot photographs in constructed fantasy worlds as if travelling in real life. While life-like graphics manufactured by the computers raise questions about authenticity and truthfulness of the image, the possible future of the photography as socially efficient visual knowledge is in constant flux. This article aims to reflect on today’s trends in in-game photography and tries to foresee how this emerging genre and its constructed realities will transpose the old with the new photographic data in the post-truth condition fostering for re-evaluation of photography truth-value.

Abstract:
Despite the fact that in recent years the anthropologist's arsenal has significantly expanded due to the intro-duction of digital 3D scanning, computed tomography, microtomography, etc. into the practice of anthropological research, for most researchers photography remains an important part of the scientific process. Moreover, the resulting images are increasingly subject to higher requirements, since they often appear in scientific circulation much faster than before, bypassing editors and professional retouchers of publishers thanks to various kinds of Internet resources, such as presentations, on-line Internet conferences, reports, etc. In this new digital reality, the researcher acts as both an expert, a director, and an operator of a photo session and is solely responsible for the quality of the result and for its compliance with the goals of the shooting. The high intelligence of modern digital cameras creates a false impression in the beginner’s mind that camera can always be given freedom in making decisions regarding the shooting parameters. However, as shown in the article, there are a number of shooting situations when targeted manual management of shooting parameters is necessary to obtain a positive result. The following information will help the photographer do this. The purpose of our article is to help the researcher anthropologist qualitatively solve his problems using a digital camera. We will try to give an idea of those basic concepts, features of technology and techniques that determine the work of a photographer within the digital space. To this end, the article discusses the main technical and methodological techniques of anthropological photography within the digital space. A brief definition of the basic concepts of the “digital world” and the most important technical characteristics of modern digital cameras are given. The main part of the article is devoted to photography of paleoanthropological materials. Particular attention is paid to the shooting of the skull and odon-tological materials. Specific recommendations are given on the management of shooting parameters and on the organization of the shooting process, the use of which will allow the researcher to obtain high-quality digital pho-tographs of the studied anthropological objects that meet both the requirements of modern printing and the re-quirements of representation on Internet resources.

Abstract:
Photography traditionally generates a truth-claim, while at the same time undermining it by holding the potential of being altered or staged. Since the rise of digital techniques, we are facing different (and easier) ways to manipulate pictures, leading to the notion of the digital photograph as generally mutable and therefore not trustworthy. But as there have been more and easier ways to “manipulate” photographs, so has there been an increase in the ways to detect them. Which today puts digital forensics in the position of re-establishing “reality” as a referential point by tracing every step of the process of alteration, turning the dubitative image into one that is doubt-free once its metadata has been analysed. But is this the whole story? By addressing digital forensic practices that have been used within the investigation of the Abu Ghraib torture scandal, I am showing that the hidden narrative of photographic production can be dug up by using forensic methods, but not without creating a new narrative.

Abstract:
Context The field of pathology is driven by microscopic images. Educational activities for trainees and practicing pathologists alike are conducted through exposure to images of a variety of pathologic entities in textbooks, publications, online tutorials, national and international conferences, and interdepartmental conferences. During the past century and a half, photographic technology has progressed from primitive and bulky, glass-lantern projector slides to static and/or whole slide digital-image formats that can now be transferred around the world in a matter of moments via the Internet. Objective To provide a historic and technologic overview of the evolution of microscopic-image photographic tools and techniques. Data Sources Primary historic methods of microscopic image capture were delineated through interviews conducted with senior staff members in the Emory University Department of Pathology. Searches for the historic image-capturing methods were conducted using the Google search engine. Google Scholar and PubMed databases were used to research methods of digital photography, whole slide scanning, and smart phone cameras for microscopic image capture in a pathology practice setting. Conclusions Although film-based cameras dominated for much of the time, the rise of digital cameras outside of pathology generated a shift toward digital-image capturing methods, including mounted digital cameras and whole slide digital-slide scanning. Digital image capture techniques have ushered in new applications for slide sharing and second-opinion consultations of unusual or difficult cases in pathology. With their recent surge in popularity, we suspect that smart phone cameras are poised to become a widespread, cost-effective method for pathology image acquisition.

Abstract:
The author used digital photography to supplement learning of biotechnology by students with a variety of learning styles and educational backgrounds. Because one approach would not be sufficient to reach all the students, digital photography was used to explain the techniques and results to the class instead of having to teach each student individually. To analyze the effectiveness of this teaching technique, the students' responses on various examination questions were analyzed.

Abstract:
Environmental history projects using repeat photography often involve the acquisition of large collections of historical and current images, matching those images for comparative analysis, and then cataloguing and archiving the imagery for long-term storage and later use (Webb et ah, 2010). When used in combination with other techniques, repeat photography is an excellent tool for documenting change (Gruell, 2010) and has been used in a variety of disciplines, including historical ecology, to determine changes in plant populations, soil erosion, climate trends and ecological processes to name a few. Historical photographs often provide greater temporal range to an analysis compared to, for example, satellite imagery and in many cases even aerial photography (Gruell, 2010).

A DISSERTATION PRESENTED TO THE FACULTY OF INFORMATICS AND DESIGN OF THE CAPE PENINSULA UNIVERSITY OF TECHNOLOGY IN FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MAGISTER TECHNOLOGIAE PHOTOGRAPHY CAPE PENINSULA UNIVERSITY OF TECHNOLOGY 2013
This study deals with the pitfalls and standards associated with the digitisation of photographic artefacts in formal collections. The popularity of the digital medium caused a rapid increase in the demand for converting images into digital files. The need for equipment capable of executing the task successfully, the pressure on collection managers to display their collections to the world and the demand for knowledge needed by managers and operators created pressure to perform optimally and often in great haste. As a result of the rush to create digital image files to be displayed and to be preserved, the decisions that are being made may be questionable. The best choice of file formats for longevity, setting and maintaining standards to guarantee quality digital files and consultation with experts in the field of digitisation as well as attention to best practices are important aspects which must be considered. In order to determine the state of affairs in countries with an advanced knowledge and experience in the field of digitisation, a comprehensive literature study was done. It was found that enough information exists to enable collection managers in South Africa to make well informed decisions to ensure a high quality of digital collection. By means of questionnaires, a survey was undertaken amongst selected Western Cape image preservation institutions to determine the level of knowledge of the managers who are required to make informed decisions. The questionnaire was designed to give insight into choices being made regarding the technical quality, workflow and best practice aspects of digitisation. Comparing the outcome of the questionnaires with best practices and recommended standards in countries with an advanced level of experience it was found that not enough of this experience and knowledge is used by local collection managers although readily available. In some cases standards are disregarded completely. The study also investigated by means of questionnaires the perception of the digital preservation of image files by fulltime photographic students and volunteer members of the Photographic Society of South Africa. It was found that uncertainty exist within both groups with regard to file longevity and access to files in five to ten year's time. Digitisation standards are set and maintained by the use of specially designed targets which enable digitising managers to maintain control over the quality of the digital content as well as monitoring of equipment performance. The use of these targets to set standards were investigated and found to be an accurate and easy method of maintaining control over the standard and quality of digital files. Suppliers of digitising equipment very often market their equipment as being of a high quality and being able to fulfil the required digitisation tasks. Testing selected digitising equipment by means of specially designed targets proved however that potential buyers of equipment in the high cost range should be very cautious about suppliers' claims without proof of performance. Using targets to verify performance should be a routine check before any purchase. The study concludes with recommendations of implementing standards and it points to potential future research.

Abstract:
This thesis explores the contemporary genre of popular digital photography, with a specific look at photographs taken in/of Iran. It focuses on the contemporary practice of 'photoblogging' or photography-based weblogging. Photoblogs are the result of the daily posting of digital photographs concerning everyday life in Iran on personal blogs specifically dedicated to photography. The title of the thesis, Camera Iranica, refers to the subject and scope of the study, as well as to its digital-ethnographic field site. I demarcate this as a conceptual and transnational cultural field, encompassing the multitude of places and spaces, on- and offline in which Iranians across the world engage in the practice of producing and viewing popular digital photography. Iranian photoblogs are shown to operate in a manner contingent upon a particular 'visual legacy' of contested cultural identity politics since the Islamic Revolution of 1979, propagated inside Iran and in 'the West'. The thesis traces the social, economic and political implications of developments in photography and digital technologies in Iran in light of this backdrop, and explores how and why Iranians in Iran and abroad are taking up popular digital photography for visual storytelling projects, with 'Iran' as their visual subject. Based on the study's empirical findings, I extrapolate theoretical arguments concerning historical and cultural understandings of digital photographs shown and seen in online environments, and propose innovative methodological strategies for digital-visual anthropologists to continue work in these fields.

Abstract:
In the 19th century, the stillness of movement during a photographic exposure required a staging based on academic traditions. Staging is the »spatialization« of a present absence – comparable to »writing« in the sense of Derrida. With the increasing mobility of camera techniques from the 20th century onwards, the focus is no longer on the reproduction of a moment, but instead on its performative invention.With the digital photography of the 21st century, a transformation from theatrical to functional staging takes place. The history of the writing scene of photography illustrates the interplay between concealment through technology and re-aestheticization, which with increasing oscillation turns into motor dizziness.

Abstract:
AbstractFace morphing is a technique to combine facial images of two (or more) subjects such that the result resembles both subjects. In a morphing attack, this is exploited by, e.g., applying for a passport with the morphed image. Both subjects who contributed to the morphed image can then travel using this passport. Many state-of-the-art face recognition systems are vulnerable to morphing attacks. Morphing attack detection (MAD) methods are developed to mitigate this threat. MAD methods published in literature are often trained on a limited number of or even a single dataset where all morphed faces are created using the same procedure. The resulting MAD methods work well for these specific datasets, with reported detection rates of over 99%, but their performance collapses for face morphs created using other procedures. Often even simple image manipulations, like adding noise or smoothing cause a serious degradation in performance of the MAD methods. In addition, more advanced tools exist to manipulate the face morphs, like manual retouching or morphing artifacts can be concealed by printing and scanning a photograph (as used in the passport application process in many countries). Furthermore, datasets for training and testing MAD methods are often created by morphing images from arbitrary subjects including even male-female morphs and morphs between subjects with different skin color. Although this may result in a large number of morphed faces, the created morphs are often not convincing and certainly don’t represent a best effort attack by a criminal. A far more realistic attack would include careful selection of subjects that look alike and create high quality morphs from images of these subjects using careful (manual) post-processing. In this chapter we therefore argue that for robust evaluation of MAD methods, we require datasets with morphed images created using a large number of different morphing methods, including various ways to conceal the morphing artifacts by, e.g., adding noise, smoothing, printing and scanning, various ways of pre- and post-processing, careful selection of the subjects and multiple facial datasets. We also show the sensitivity of various MAD methods to the mentioned variations and the effect of training MAD methods on multiple datasets.

Abstract:
Automatic detection of planar regions in point clouds is an important step for many graphics, image processing, and computer vision applications. While laser scanners and digital photography have allowed us to capture increasingly larger datasets, previous approaches for planar region detection are computationally expensive, precluding their use in real-time applications. We present an O(n log n) technique for plane detection in unorganized point clouds based on an efficient Hough-transform voting scheme. It works by clustering sets of approximately co-planar points and by casting votes for these clusters on a spherical accumulator using a trivariate Gaussian kernel. A comparison with competing techniques shows that our approach is considerably faster and scales significantly better than previous ones, being the first practical solution for deterministic plane detection in large unorganized point clouds.

Abstract:
This presentation proposal advances a pedagogical case study that focuses on innovative ways of promoting visual literacy for undergraduate students through lens-based image-making and digital technologies. The curriculum was designed to be delivered throughout an academic semester at Auckland University of Technology South Campus, Manukau City, Aotearoa New Zealand. The content is formatted for first-year students of the Diploma in Arts endorsed in Communication Design. The Diploma in Arts is appealing to students who may be seeking a shorter design qualification. In addition, the programme provides for students who have not met or have narrowly missed University Entrance (UE) criteria. The presentation focuses on the structure and contents of the pedagogical experience where lecturers and students are connected in the design studio through agency and literacy rather than just observing pedagogical prescriptions. In this active environment, the hidden curriculum that deals with the participant's cultural background and natural epistemologies is valued and validated. In creating the engagement for visual literacy, the brief requires students to consider aspects of community, taking the role of a storyteller equipped with skills to create visual content that is meaningful and actual. The course is divided into two parallel design studio approaches: one that deals with visual literacy through the photographic image and practice; and the other is concerned with aspects of the nature of the media, augmented reality and image dissemination in digital platforms. The first area focused on visual literacy through photographic practice, using the politics of photographic language and representation, employing portraiture analysis and image creation. This approach encompasses the conceptual aspects associated with photographic images and the technical aspects of lens-based image-making. The second area focused on understanding digital media, the application of tools and how to take advantage of the interactive environment to promote awareness and reflect change in the community. This part of the brief intended to create an understanding of the issues associated with online environments, providing students with skills to operate creatively and fluidly in response to the fast-paced nature of online image-sharing platforms. Within this context, techniques of digital image construction and manipulation were investigated in the light of industry applications and best practice workflows. These learning areas were underpinned by an online blog where students actively recorded their design process, tests, and contextual influences that impacted their design practice. The studio environment fostered an inclusive and participatory form of teaching and learning and employed students' smartphones as an accessible tool to produce and understand images. The project contributes to knowledge about the design studio through a framework for Visual literacy and media education, where students learn principles of photography practice and digital technologies. It contributes to reflections about the use of mobile phone technologies as a common entry way apparatus to visual literacy and imagery generator.

Abstract:
Photographic methods of analyzing vehicles and scenes for the purpose of accident reconstruction have been well researched and documented. Photogrammetric analysis has appeared in various forms and levels of complexity over the years. Mathematical relationships have been researched and presented depicting the methods and bases of these techniques. This paper will present some new tools and methodologies in the process of photographic analysis. The PhotoModeler program will be utilized to demonstrate applications of digital photogrammetry in the field of accident reconstruction. Several different methodologies, including single and multiple photograph projects using calibrated and inverse cameras, will be evaluated and demonstrated. Additionally, comparisons to traditional methods of measurements will be presented. It will be demonstrated that the use of digital photogrammetry has advanced the science of accident reconstruction by employing computer and digital technology to achieve greater efficiency and improved accuracy.

Abstract:
This paper describes two pedagogical practices based on Francis Bacon’s graphic Works. One in a curricular context, held at Escola Superior Artística do Porto, and the other in an extracurricular context held at Universidade Lusófona do Porto (both in Portugal), which aimed to stimulate students towards a critical analysis and interpretation of Francis Bacon's work and its recreation using contemporary digital media. This initiative was integrated in the Graphic Works of Francis Bacon exhibition at the World of Wine Museum in Vila Nova de Gaia and was the result of a collaboration between this Museum, the Academy and the Renschdael Art Foundation, a collaboration that aimed to give voice and life to a debate emerging from the exhibition of the work of art and its multimedia translation. Hence, it was intended to complement the exhibition of the artist's works with a multimedia language, through multiple interpretations and digital animations of the Painter's work made by the students and targeted at digital natives as one stream of the exhibition was to target local primary and secondary schools.The participants involved in this project came from various BAs, including Communication Design, Fine Arts and Intermediate, Visual Arts - Photography, Cinema and Audiovisual, Audiovisual Communication and Multimedia, Video Games and Multimedia Applications. This allowed to bring together multidisciplinary groups of students with different profiles and backgrounds, contributing to a myriad of results both in visual terms and technological resources, which included approaches such as: the use of techniques close to rotoscoping in which students created drawings frame by frame over the original images; the exploration of cut-out animation techniques; the recreation of Francis Bacon's work in 3D; explorations of image manipulation, editing, and video effects.In an academic context, these practices resulted in an in-depth knowledge of the work of an artist from a generation different from that of the students; an opportunity for them to work with a real client, applying in a project the knowledge obtained in various curricular units of the BAs they are attending; and the possibility of seeing their work integrated in an international exhibition. As regards to the Graphic Works of Francis Bacon exhibition, this academic project brought a new dynamic to the space combining graphic works by the Painter with multiple interpretations of a generation to whom digital media are omnipresent.In this paper, the pedagogical practices adopted in both Universities are described, projects by students are analyzed as well as the contribution that these projects brought to the exhibition through information gathered from visitors, from articles published on the event and through an interview conducted with the exhibition curator.The exhibition, according to the commissioner, Charlotte Crapts, had an "impressive" turnover bearing in mind that the country was going through Covid restrictions. In the commissioner’s view, the multimedia interventions created a bridge with the educational sector and following this, the exhibition interacted with a great number of youngsters. This was a pioneer exercise in the exhibition space that will be followed in future exhibitions.
