Junita Arneld's 2013 photographic series for Alam & Budaya Indonesia (Gedung Arsip Nasional, Jakarta) presents a visceral documentation of West Sumatra's Pacu Jawi bull races through high-speed photography. Her technical approach combines extreme proximity with fast shutter speeds (1/1000s+) to freeze the chaotic energy of these traditional races while preserving the intimate human-animal dynamic. Arneld's shallow depth of field isolates subjects from the muddy terrain, transforming splashing water and flying soil into dynamic visual elements. The images transcend mere action photography by capturing the cultural essence of the ritual - the synchronized movement of man and beast, the tension of competition, and the deep connection to rural traditions. This series demonstrates how technical precision can amplify cultural storytelling, creating images that convey both the physical intensity and spiritual significance of Indonesia's living heritage.

Focusing on domestic photographic albums and the faded metadata embedded within them, this essay argues for the critical importance of visual materiality and presentational form in understanding photographs. It proposes that accurate digitisation must account for not just the content image but also the tactile, contextual, and paratextual traces of the physical photograph. Metadata becomes the mechanism through which this translation from material to digital might occur.

In this article, information about the properties, working principles and recent developments of CCD and CMOS sensors used in astronomy are given. Until the development of camera technology, sky observations were made using photographic plates in telescopes. With the development of CCD sensors in the 1960s, photographic plates were replaced by powerful cameras with CCD and CMOS sensors. Even today, all observations made in the optical field are made with the data taken by placing these cameras in the ocular part of the telescope. It is of great importance to understand the sensor technology in order to understand the observation techniques. This article has been prepared to fill this gap.

2025, Virtuelle Investigationen. Revisionen des Indizienparadigmas in Literatur und Kunst

Inwiefern schlieBen Open Source Investigations eine Revision des Indizienparadigmas ein? Der Aufsatz beantwortet diese Frage, indem er anhand von Fallbeispielen von Rechercheagenturen (bellingcat und Forensic Architecture) und investigativen Fotografen (Trevor Paglen und Edmund Clark) eine Verschiebung im Spurbegriff herausarbeitet: Im Rahmen digitaler Recherchen sind Spuren durch Datenverarbeitung hervorgebrachte mediale Artefakte, sie werden also nicht am Tatort vorgefunden, sondem rechnerisch produziert. In den Falldarstellungen und Methodenreflexionen der
Akteur:innen können dabei verschiedene Modi der virtuellen Spur unterschieden werden.

2025, Die Materialität des Digitalen

Schon häufiger wurde der Begriff der Spur für eine Ideologie-und Metaphysikkritik dienstbar gemacht. Laut Ginzburg suchen Spurenleser*innen nach einem tieferen Zusammenhang, »der die Phänomene der Oberfläche erklärt« und damit den »ideologischen Nebel« lichtet (Ginzburg 1979(Ginzburg /1995: 36f.): 36f.). Dabei ist nach Krämer von der Materialität der Spur auszugehen: »Spuren gehören der Welt der Dinge an. Nur kraft eines Kontinuums in der Materialität, Körperlichkeit und Sinnlichkeit der Welt ist das Spurenhinterlassen und Spurenlesen also möglich« (Krämer 2007a: 15). So hat auch Derrida in einem ideologie-und metaphysikkritischen Sinn den Begriff der Spur in den Vordergrund gestellt, um die unvorgreifliche Materialität der Schrift zu betonen und sie von der Dominanz der Stimme zu befreien (Derrida 1967: 293-340). Die Materialität von Spur und Schrift schien allerdings mit der Umstellung auf digitale Textverarbeitung an einen Wendepunkt gekommen, wenn man mit Mark Poster glaubt, dass »the computer dematerializes the written trace« (Poster 1990: 111). Doch hat sich der Glaube an die Immaterialität digitaler Daten, wie er sich in Licht-, Blitz-und Geschwindigkeitsmetaphern niederschlägt, seinerseits als »medial ideology« und »screen essentialism« herausgestellt . Denn die Einschreibeverfahren digitaler Daten sind nicht weniger materiell konfiguriert als

We evaluated the applicability of the Visible and Near Infrared bands (15 m spatial resolution) of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) imagery in mapping land use ⁄ cover in the drylands of northern Ethiopia. Ground Control Points were collected from the field using Geographic Positioning System in which half of them were used for classification and the remaining for accuracy assessment. The image was classified into four dominant land use ⁄ cover types that represent the major habitats of the study site. Image classification was done using pixel-based supervised classification with the Maximum Likelihood Classification algorithm. The accuracy of classification was evaluated using error matrix and Kappa statistics. Finally, we found an overall classification accuracy of 80% and this implies that ASTER imagery can be used as a good source of data in mapping biodiversity at habitat scale in data scarce drylands of northern Ethiopia.

With the rise of digital photography and social networking, people are sharing personal photos online at an unprecedented rate. In addition to their main subject matter, photographs often capture various incidental information that could harm people's privacy. While blurring and other image filters may help obscure private content, they also often affect the utility and aesthetics of the photos, which is important since images shared in social media are mainly for human consumption. Existing studies of privacy-enhancing image filters either primarily focus on obscuring faces, or do not systematically study how filters affect image utility. To understand the trade-offs when obscuring various sensitive aspects of images, we study eleven filters applied to obfuscate twenty different objects and attributes, and evaluate how effectively they protect privacy and preserve image quality for human viewers.

Esta monografia é focada não só em fotografia, mas, especificamente, no fazer fotográfico em sua definição mais verdadeira: o reproduzir de uma realidade criada. No capítulo um, discuto meu processo de criação, sublinhando as razões subjetivas que me levaram à produção de fotogramas, bem como a descrição objetiva das etapas que transpus até o resultado que aqui apresento. Para situar historicamente meu objeto de estudo, trago uma rápida biografia da técnica do fotograma, referenciando meu trabalho em dois dos principais nomes desta: Man Ray e Moholy-Nagy. Concluindo, me permito surpreender em como o discurso teórico aqui elaborado, potencializa meu processo criativo, se tornando o principal catalisador para que essa produção plástica do imaginário não se encerre nesses primeiros passos aqui expostos.

The article explores advanced image processing techniques for pigment discrimination in rock art paintings, emphasizing color separation using RGB (red, green, blue) and LHC Uv (Luminance, Hue, Chroma) imagery. It highlights the use of dimensionality reduction methods such as Principal Components Analisys PCA and Independent Component Analysis (ICA), with a focus on Gaussian Mixture Models (GMM) for probabilistic classification of image elements. This approach, applied to the Chomache archaeological site on the northernmost coast of the Atacama Desert in Chile, reveals previously undetected motifs and details, offering a nuanced perspective in rock art documentation and analysis. This proposal reinforces the value of rock art panel not only as a finished product but as a process.

Understanding pediatric occupant postures can help researchers indentify injury risk factors, and provide information for prospective injury prediction. This study sought to observe lateral head positions and shoulder belt fit among older child automobile occupants during a scenario likely to result in sleeping - extended travel during the night. An observational, volunteer, in-transit study was performed with 30 pediatric rear-seat passengers, ages 7 to 14. Each was restrained by a three-point seatbelt and was driven for seventy-five minutes at night. Ten subjects used a high-back booster seat, ten used a low-back booster seat, and ten used none (based on the subject height and weight). The subjects were recorded with a low-light video camera, and one frame was analyzed per each minute of video. The high-back booster group exhibited a statistically significant (p<0.05) decrease in the mean frequency of poor shoulder belt fit compared to the no-booster and low-back booster groups...

Has the sublime gone? If so, where? Can the sublime go anywhere, or is it our relationship to it... our perception of it that has changed? After the demise of Romanticism in the 19th Century and the advent of Modernism, new paradigms emerged that diminished the notions of beauty and the sublime. The increasing emphasis on a positivist notion of culture as that which is moving ever forward and upward, seems to have been fulfilled by new technologies, unknowable and thus terrifying as manifestations of a new sublime. Gilbert-Rolfe observes that "technology has subsumed the idea of the sublime because it, whether to a greater extent or an equal extent than nature, is terrifying in the limitless unknowability of its potential..." 2 In contrast to the technological sublime, the notion of silence, a pause, but also a kind of resistance has simultaneously emerged that provides an introspective aspect suggesting an alternative sublime. Roger Connah observes: "...the possibility of silence offers not only retreat, not only refuge, but respite from the world's excess." 3 These conditions provide a juxtaposition, and therefore a co-existence of qualities informing and affecting our own perceptions. But how do they co-exist? What are their conditions and their meanings in a contemporary society? In this paper I wish to address these issues and elucidate new interpretations of the contemporary sublime. Nature 4 (and its forces) has historically elicited emotions ranging from the beautiful and tranquil to the awesome and terrifying.

Reconstruction of 3D, especially on height extraction using digital aerial photos taken from a non-metric camera and Unmanned Aerial Vehicle (UAV) is a challenging study. The purposes of this study are: (1) to determine the precision of an object's height reveal from a 3D model, and (2) to establish procedures to deliver the optimal result. Two or more overlapping aerial photos can be constructed into a 3D model by applying principles of collinearity and epipolar geometry using 3D reconstruction algorithm. Since there is an instability on a non-metric digital camera, the camera must be calibrated before 3D reconstruction is process, in that way the quality of spatial extraction, then can be measured. The study is conducted using 24 megapixels resolution Sony NEX7 digital camera and Hexacopter UAV. Camera Calibration Toolbox was utilized to calculate intrinsic parameters of the camera and a specific program is developed using MATLAB in order to build the 3D model and to obtain the object's height. The result validation is done by comparing the height from 3D model with that one measured using Electronic Total Station. The accuracy of the object's height up to 1 mm was successfully achieved, with largest height prediction error reaches of 15.2 cm at 70 m flying height above ground level.

continuo avance de la técnica, los sistemas incrementan sus prestaciones y capacidad, lo que se refleja en la aparición de nuevos formatos gráficos. Un ejemplo de lo afirmado es la "reciente" aparición del formato JPEG, basado en esquemas de compresión disipadora o con pérdida de datos. Sin embargo, a estas alturas del desarrollo, sí existen algunos tipos de archivo que destacan por encima del resto gracias a su capacidad, versatilidad y difusión. Primeramente es necesario hacer una distinción entre los formatos raster o de barrido y el EPSF, formato PostScript desarrollado para ilustraciones e infográficos. Cada uno tiene una finalidad distinta y la manera de trabajar con ellos también es diferente. Los primeros (de barrido) están basados en mapas de bits, es decir, en la descripción de los píxels mediante coordenadas, mientras que el segundo está orientado a objeto (se describen los objetos que forman una imagen -líneas, polígonos, curvas, etc.) y su ubicación. Existen múltiples formatos basados en mapa de bits, pero sólo analizaremos tres: aquellos que pueden ser de verdad operativos en un archivo informatizado que ha de servir imágenes de gran calidad a múltiples finalidades, tanto en color como en blanco y negro (hoy predominante en el mundo de la prensa diaria). En primer lugar el TIFF (Tagged Image File Format), es el formato quizá más conocido. Soporta imágenes desde 1 a 24 bits por píxel (desde formato por líneas o line art hasta calidad fotográfica) y puede comprimirse. Otro formato de amplia y creciente difusión es el JPEG, con unas prestaciones en cuanto a reducción del tamaño de los archivos realmente asombrosas. La clave radica en la antes mencionada pérdida de información, pero en cantidades prácticamente tan insignificantes que no suponen un grave inconveniente pasa su uso. El último de los formatos estudiados será el PHOTO CD, un desarrollo específico de Kodak que no puede ser definido como "formato" a secas, ya que conlleva mucho más: toda una filosofía de la imagen digital. Su reciente aparición en el mercado todavía no ha permitido su asentamiento como estándar, pero su innovador solución a la fotografía doméstica digital y el aval de tener como respaldo a la primera empresa mundial en fotografía -Kodak-facilitará mucho el proceso en un breve plazo.

This article examines spatial dynamics in Land Use/Land Cover (LU/LC) change in Kipengere ranges in the southern highlands of Tanzania. Though humans have been modifying land to obtain food and other essentials for thousands of years, the current trends, extents, and intensities of land-use change are far greater than ever in history. The trends seem to be unique. The Geographical Information System (GIS) was employed to track land use/land cover from 1984 to 2014. Household surveys, in-depth interviews, field observations, and Focus Group Discussions (FGDs) supplemented the information generated by the geographical information system. The data were collected from 104 respondents. Through the geographical information system, six land use classes namely: agriculture with scattered settlements, bushlands, woodlands, grasslands, plantation forests, and native trees were identified. All land use/ land cover classes changed over time. Changes in land use were caused by out-migration, the decline in soil fertility, the absence of a land use plan, and campaigns for planting invasive tree species mainly pines and eucalyptus. The study, thus, recommends the introduction of a landuse plan in each village to enhance natural resource management and reduce conflicting land uses in a specific area.

Objective: To examine the relationship between baseline and post accelerometer derived physical activity (PA) in 9-10 year old children participating in iCook 4-H, a 16-week, 5-state, randomized control family centered childhood obesity prevention program. Design, Setting and Participants: This family focus intervention was designed to promote PA through lifestyle modifications. Between group differences in minutes-per-day and intensity of PA were determined on 76 (Intervention n¼51; Control n¼25) accelerometer compliant participants. Outcome Measures and Analysis: All subjects wore an accelerometer (Actigraph GT3X+) for 7 days at baseline and post intervention assessment. Mean daily minutes of accelerometer derived sedentary time (ST) and PA including light (LPA), moderate (MPA), vigorous (VPA) and moderate-to-vigorous (MVPA) were evaluated during waking hours. A multivariate test, Wilks' Lambda, was used to determine the between group differences of PA from pre to post. Statistical significance was set at p # 0.05. Results: There were no significant differences between groups from baseline to post intervention in any intensity category of PA (mean min/dayAESD; p-value) ST baseline treatment [BT] 546 AE 57, baseline control ([BC] 547AE 62, post treatment [PT] 580 AE63, post control [PC] 563AE66 ; p¼0.28), LPA (BT 244AE48, BC 239AE50, PT 217AE52, PC 228AE50; p¼0.25), MPA (BT 33AE10, BC 36AE12, PT 28AE9, PC 33AE13; p¼0.61), VPA (BT 16AE9, BC 18AE9, PT 14AE7, PC 16AE8; p¼0.74), and MVPA (BT 50AE17, BC 54AE19, PT 42AE14, PC 49AE20; p¼0.58). Conclusions and Implications: Although there was not a significant increase in any category of physical activity due to the lifestyle intervention, iCook 4-H was able to encourage participants to maintain current activity levels.

An easy-to-use and cheap diagnostic tool based on digital photography and 2D-FFT imaging processing is described that can be used to monitor the corrosion process occurring over time on the surface of metallic works of art in indoor and outdoor environments and to assess the stability of the materials employed for restoration. The proposed solution has the advantage of not requiring standard lighting and artifacts manipulation, that are not easily achievable in real applications. The imaging algorithm is capable of highlighting the changes in the surface uniformity due to the corrosion process and can be used to put in evidence the beginning of dangerous localized corrosion phenomena onto the metallic surface. Although this technique does not allow a quantitative measurement of the corrosion rate, it has proved to be an effective approach to assess the stability of protective coatings. The proposed processing has been tested in laboratory to asses the stability of SiO 2 -like protective coatings deposited by PECVD on a set of silver reference alloys submitted to a tarnishing test in the presence of H 2 S vapors.

Commencing in the autumn of 2017, the Theban Tomb 110 Epigraphy and Research Field School (ERFS) Project initiated a photographic survey component to shed new light on ancient inscriptions and broaden the application of photographic surveys in educational contexts. Over three field seasons, this extensive program has yielded a structured and pragmatic surveying methodology that exemplifies the seamless integration of advanced surveying techniques in archaeological work, effectively merging conventional epigraphy with contemporary technology. Beyond its research contributions, the TT110 project provided invaluable training opportunities for Egyptian archaeologists. It served as a tangible example of harmoniously merging classical epigraphy with emerging technologies, highlighting the vast potential for documenting, conserving, and safeguarding Egypt's historical heritage. This collaborative initiative underscores the paramount significance of interdisciplinary knowledge exchange within the realm of Egyptology.

To assess the effects of (1) mydriasis and (2) single versus three field photography on screening for diabetic eye disease using digital photography Method: Slit lamp examination findings were compared to digital fundal photographs for the detection of any retinopathy and for referable retinopathy in 398 patients (794 eyes). A Topcon TRC-NW6S digital non-mydriatic fundus camera was used. Three photographic strategies were used: undilated single field, dilated single field, and dilated multiple fields. The photographs were presented in random order to one of two retinal screeners. For the single field photographs the screeners were masked to the use of mydriatics. In 13% of fundal photographs, grading was performed by both, rather than just one grader. Results: Mydriasis reduced the proportion of ungradable photographs from 26% to 5% (p,0.001). Neither mydriasis nor three field photography improved the sensitivity or specificity for the detection of any retinopathy or of referable retinopathy when compared with undilated single field photography. The sensitivity and specificity for detecting referable retinopathy using undilated single field photography was 77% (95% CI 71 to 84) and 95 % (95% CI 93 to 97) respectively. Using dilated single field photography the figures were 81% (95% CI 76 to 87) and 92% (95% CI 90 to 94) respectively. Using dilated three field photography the figures were 83% (95% CI 78 to 88) and 93% (95% CI 91 to 96) respectively. Intergrader reliability for the detection of referable retinopathy in gradable photographs was excellent (Kappa values 0.86-1.00). Conclusions: Mydriasis reduces the technical failure rate. Mydriasis and the three field photography as used in this study do not increase the sensitivity or specificity of detecting diabetic retinopathy.

Like many successful photographers, Rossman (or Ross), discovered his passion for photography at an early age. His journey began at 13 years when his cousin first introduced him to the art form. Each day, during his young school days, on his way to and from classes, Ross would pass a small shop in Zabbar, owned by Joseph Cassar. Primarily a bazaar for sweets and basic school supplies, the shop also showcased Cassar's passion for photography, offering monochrome printing services. Intrigued, Ross often observed as Cassar demonstrated the photographic process, generously sharing chemicals and paper to further fuel the boy's experimentation. These early experiences became the foundation of Ross' photographic journey, paving the way for the remarkable achievements that lay ahead. Ross was born in Zabbar on 29

On Instagram, where visibility is paramount, mothers in Turkey navigate the traditional belief in the evil eye (nazar) by redefining a new consensus for sharing infant images. These mothers create a unique visual habit of sharing that both shields and showcases, reshaping what is deemed 'Instagrammable.' Drawing on a digital ethnography of 65 Instagram profiles and an online survey, this study examines the visual and linguistic maneuvers mothers employ to protect infants from the malevolent gaze while negotiating the visibility of the mother and child. The research highlights how mothers' sharing, editing, and framing choices, mapped under “Protective Partiality” and “Eliciting Safeguard,” reflect the ongoing politics of visibility, balancing cultural traditions with contemporary digital practices. This study contributes to the understanding of contemporary motherhood's performance and negotiation on Instagram, offering insights into the complexities of visual culture.

We describe the application of ethnography and experimentation to the specification and evaluation of a browser to support collaborative sharing of photographs in family contexts. In an extension of this mixed-method approach, we adopted an ethnographic stance to the posthoc analysis of couples' interactions recorded during the experimental studies. The experiments and post-experiment analyses yielded usability enhancements and unexpected interaction patterns among couples in categorising and retrieving photographs that led to browser redesign.

We report on the use of photos in families as an example of a mundane technology. We firstly consider issues regarding mundaneness. We then review some previous work on domestic media and on photos in the home. In the main part of the paper we report on some findings from fieldwork in the UK and China, focusing on the display of family photos in the home. We show that family photos are placed and configured, express relationships and obligations, serve as reminders, and are aesthetically objects in themselves. We then proffer some insights into 'mundane technologies' and note the strengths and weaknesses of regarding technology in this way.

Resumo | o artigo partiu da questão: porque o conceito de fotografia experimental apenas recentemente vem sendo problematizado, se as práticas experimentais na fotografia são tão antigas quanto o meio fotográfico? Para tal, realizou-se uma breve reflexão acerca da história desse conceito, que só apareceu com mais clareza e persistência apenas nos anos 2000, no momento em que as teorias ontológicas da fotografia perdem força diante do hibridismo entre linguagens que caracteriza a imagem contemporânea. Aprofundamos o debate sugerindo que o experimental seja estudado como um conceito que por vezes adquire uma conotação política em obras de alguns artistas latino-americanos, que revelam as bases ideológicas da fotografia, operando críticas ao pensamento ocidental moderno, inserido-se nos debates mobilizados pelas teorias decoloniais. Isso foi demonstrado na análise visual dos projetos Atlântico Vermelho, de Rosana Paulino (2017) e Botannica Tirannica, de Gisele Beiguelman (2022).

The composition of surficial salts formed near dry and drying saline lakes are partly the product of processes active in the unsaturated zone between the ground surface and the water table. These processes were investigated by determining the abundance of water-extractable solutes in sediment from the ground surface to the water table (~2.8 m) beneath Franklin Lake playa, California.

The interactions between playa hydrology and playa‐surface sediments are important factors that control the type and amount of dust emitted from playas as a result of wind erosion. The production of evaporite minerals during evaporative loss of near‐surface ground water results in both the creation and maintenance of several centimeters or more of loose sediment on and near the surfaces of wet playas. Observations that characterize the texture, mineralogic composition and hardness of playa – surfaces at Franklin Lake, Soda Lake and West Cronese Lake playas in the Mojave Desert (California), along with imaging of dust emission using automated digital photography, indicate that these kinds of surface sediment are highly susceptible to dust emission. The surfaces of wet playas are dynamic surface texture and sediment availability to wind erosion change rapidly, primarily in response to fluctuations in water‐table depth, rainfall and rates of evaporation. In contrast, dry playas are cha...

Playa type, size, and setting; playa hydrology; and surface-sediment characteristics are important controls on the type and amount of atmospheric dust emitted from playas. Soft, evaporite-rich sediment develops on the surfaces of some Mojave Desert (USA) playas (wet playas), where the water table is shallow (< 4 m). These areas are sources of atmospheric dust because of continuous or episodic replenishment of wind-erodible salts and disruption of the ground surface during salt formation by evaporation of ground water. Dust emission ...

One of the first and iconic imaging targets to be developed for color photography was described by McCamy, Marcus, and Davidson. That was more than thirty years ago and, for better or for worse, the Macbeth ColorChecker™ continues to be a de-facto target standard in imaging circles. The target was designed to simulate the spectral nature of critical or problematic colors for consumer photography so that color calibrations and color reproduction evaluations could be made that were consistent with scene content. However, for digital collections with limited colorgamut, or where detection of small differences in material properties is important, adopting collection-specific color test targets is often advisable. This can reduce metamerism, and sample the device signal space in the most important regions. As an example of such content, the spectral-reflectance characteristics of a collection of early photographic prints were measured. The underlying structure of the data set was investigated in terms of principal components, and a spectral reconstruction based on two principal components was demonstrated.

Stratigraphic archaeological excavations demand high-resolution documentation techniques for 3D recording. Today, this is typically accomplished using total stations or terrestrial laser scanners. This paper demonstrates the potential of another technique that is low-cost and easy to execute. It takes advantage of software using Structure from Motion (SfM) algorithms, which are known for their ability to reconstruct camera pose and threedimensional scene geometry (rendered as a sparse point cloud) from a series of overlapping photographs captured by a camera moving around the scene. When complemented by stereo matching algorithms, detailed 3D surface models can be built from such relatively oriented photo collections in a fully automated way. The absolute orientation of the model can be derived by the manual measurement of control points.

This paper examines color from multiple perspectives. A theory is proposed that the current color spaces are poorly designed for video quality and video coding purposes.

A prototype subjective database is provided that could be used to train such an algorithm. Download the dataset.
