In September 1987, early in my research at the Kenya National Archives, I came across a collection of photographs taken by a British missionary during the 1920s and early 1930s. The collection contained nearly 250 photos of the terrain and people of Kenya's Taita Hills, where I would soon be going for my fieldwork. I pored over the photo collection for a long time, and had reproductions made of twenty-five shots. The names of those pictured had been recorded in the photo album's captions. Many of the names were new to me, though a few WaTaita of the day who had figured prominently in the archival records were also captured on film. When I moved on to Taita in early 1988,1 took the photographs with me. Since I would be interviewing men and women old enough either to remember or be contemporaries of the people in the pictures, I planned to show the photos during the interviews. At first I was simply curious about who some of the people pictured were, but my curiosity quickly evolved into a more ambitious plan. I decided to try using the photographs as visual prompts to get people to speak more expansively than they otherwise might about their lives and their experiences.In the event, I learned that using the photographs in interviews involved many more complexities than I had envisaged in my initial enthusiasm. I found that I had to alter the expectations and techniques I took to Taita, and feel out some of the limitations of working with the photographic medium. I had to recognize the power relations embedded in my presence as a researcher in Taita, in my position as bearer of images from peoples' pasts, and in the photos themselves. I found, too, that I needed to come to grips with a number of issues about the politics of image production, and the historical product of those politics: the bounded, selected images that are photographs. Finally, I had to address some of my own cultural assumptions about photography and how people respond to pictures, assumptions that my informants did not necessarily share.

O presente artigo é resultado de experimentação fotográfica realizada com alunos da disciplina de psicologia jurídica de um curso de Direito, dentro do contexto de pesquisa sobre imagem. Em sala de aula foi feito o pedido de que os alunos produzissem imagens sobre a “interface Direito/Psicologia” para posterior projeção e debate sobre as mesmas e seu processo de produção. A experimentação fotográfica visibilizou os diferentes olhares, colocando foco na tensão existente entre as práticas disciplinares e interdisciplinares, na prática interdisciplinar como ferramenta importante na solução de problemas sociais complexos, problematizando, ainda, as práticas contemporâneas em Direito. Entende-se, através das noções de Mikail Bakhtin, que a experimentação fotográfica se colocou como criação estética, enquanto um processo complexo de posicionamentos axiológicos que implicam tomadas de posições em um contexto cultural constituído pela multiplicidade de vozes sociais, onde compreender é uma atividade dialógica. This article is the result of photographic experimentation carried out by students of a forensic psychology course at the Faculty of Law Dom Bosco Porto Alegre ( FDB ), within the context of research on image. This discipline tensions the assumptions of positivist Legal Psychology of the subject as an autonomous, free individual, and voice of reason. In class students were asked to produce images on "Law / Psychology interface" for projection in classroom, discussion about these images and their production process. The photographic experimentation showed different looks, tensions, and refractions that could be seen in the image production process, focusing on the tension between the disciplinary and interdisciplinary practices, and also on interdisciplinary practice as an important tool in solving complex social problems, such as violence against children and youth, social inequalities, divorce, discrimination, homoaffective relations, homeless people, prison system, psychological distress and work of waste pickers. The photos also problematize contemporary practices in law as restorative justice, special testimony and mediation. It is understood, through the concepts of Mikhail Bakhtin, that photographic experimentation stood as aesthetic creation in a complex process involving axiological positions resulting in positions taking in a cultural context constituted by the multiplicity of social voices, where understanding is not a simple passive psychological experience on other people’s action, but a dialogical activity, that in the presence of a text or an image generates many other texts and images.

RESUMO Este trabalho pretende, através do exemplo do muralismo libertário latino-americano, problematizar as relações entre educação e emancipação. É nossa compreensão que as práticas de ação direta pertinentes ao muralismo libertário, são processos constituintes de uma comunicação igualitária em franca antítese e resistência a um modo de comunicação autoritário característico da sociedade capitalista e de sua indústria cultural.  Analisaremos algumas obras dos coletivos muralistas anarquistas contemporâneos nas cidades latino-americanas, demonstrando sua orientação temática, suas estratégias de produção e representação imagética, e sua concepção explícita de uma formação cultural ampliada. Consideramos que o muralismo libertário, ao se apropriar do espaço urbano como meio de comunicação, ao ressignificar nos muros os demarcadores das desigualdades sociais, procura constituir uma cultura da resistência, materializando os fundamentos de um modo de comunicação igualitário.   Palavras-chave: Muralismo Latino-americano. Muralismo Libertário. Educação e Emancipação.   ABSTRACT The following paper aims to problematize the relationship between education and emancipation through the example of Latin American libertarian muralism. It is the authors’ understanding that the practices concerning the libertarian muralism belong to an egalitarian communication, which is openly against an authoritarian communication peculiar to the capitalist society and its culture industry. The authors will analyze some studies of the contemporary anarchist collective muralists in Latin American cities, demonstrating their thematic orientation, their strategies of image production and representation, and their explicit conception of a broad cultural formation. In addition, the authors consider that libertarian muralism, by using urban space as a means of communication, and re-defining the main aspects of social inequalities, seeks to establish a culture of resistance, materializing the foundations of an egalitarian way of communication.   Keywords: Latin American Muralism. Libertarian Muralism. Education and Emancipation.

 This research explores the shifts and continuities of representing Kathmandu City in Western cinematic and musical creations since 1970s. My research concerns with the representations of Kathmandu in the popular culture intends to explore the imagination of Kathmandu as a touristic place and how they represent the city and produce images in the popular culture which expands far beyond the visual apprehension and enjoyment of a landscape. While doing so my research first explores the representations, practices and processes of identity formation and cultural negotiations that are brought about in the city by tourism and secondly, it analyses the content and the visual representations of the movies and songs relying primarily on the theoretical tools of Popular Culture and secondarily the image production of the landscape in terms of Tourist gaze.


Content-Based Image Retrieval (CBIR) is extensively used technique for image retrieval from large image databases. However, users are not satisfied with the conventional image retrieval techniques. In addition, the advent of web development and transmission networks, the number of images available to users continues to increase. Therefore, a permanent and considerable digital image production in many areas takes place. Quick access to the similar images of a given query image from this extensive collection of images pose great challenges and require proficient techniques. From query by image to retrieval of relevant images, CBIR has key phases such as feature extraction, similarity measurement, and retrieval of relevant images. However, extracting the features of the images is one of the important steps. Recently Convolutional Neural Network (CNN) shows good results in the field of computer vision due to the ability of feature extraction from the images. Alex Net is a classical Deep CNN for image feature extraction. We have modified the Alex Net Architecture with a few changes and proposed a novel framework to improve its ability for feature extraction and for similarity measurement. The proposal approach optimizes Alex Net in the aspect of pooling layer. In particular, average pooling is replaced by max-avg pooling and the non-linear activation function Maxout is used after every Convolution layer for better feature extraction. This paper introduces CNN for features extraction from images in CBIR system and also presents Euclidean distance along with the Comprehensive Values for better results. The proposed framework goes beyond image retrieval, including the large-scale database. The performance of the proposed work is evaluated using precision. The proposed work show better results than existing works.

In modern moving image production pipelines, it is unavoidable to move the footage through different color spaces. Unfortunately, these color spaces exhibit color gamuts of various sizes. The most common problem is converting the cameras’ widegamut color spaces to the smaller gamuts of the display devices (cinema projector, broadcast monitor, computer display). So it is necessary to scale down the scene-referred footage to the gamut of the display using tone mapping functions [34].In a cinema production pipeline, ACES is widely used as the predominant color system. The all-color compassing ACES AP0 primaries are defined inside the system in a general way. However, when implementing visual effects and performing a color grade, the more usable ACES AP1 primaries are in use. When recording highly saturated bright colors, color values are often outside the target color space. This results in negative color values, which are hard to address inside a color pipeline. "Users of ACES are experiencing problems with clipping of colors and the resulting artifacts (loss of texture, intensification of color fringes). This clipping occurs at two stages in the pipeline: <list list-type="simple"> <list-item>- Conversion from camera raw RGB or from the manufacturer’s encoding space into ACES AP0</list-item> <list-item>- Conversion from ACES AP0 into the working color space ACES AP1" [1]</list-item> </list>The ACES community established a Gamut Mapping Virtual Working Group (VWG) to address these problems. The group’s scope is to propose a suitable gamut mapping/compression algorithm. This algorithm should perform well with wide-gamut, high dynamic range, scene-referred content. Furthermore, it should also be robust and invertible. This paper tests the behavior of the published GamutCompressor when applied to in- and out-ofgamut imagery and provides suggestions for application implementation. The tests are executed in The Foundry’s Nuke [2].
