The Controlled Vocabulary Survey regarding the Preservation of Photo Metadata by Social Media Websites Overview Do the social media websites or other image sharing services you use preserve your embedded photo metadata after upload? The answer to that question isn't clear, so we have been conducting an on-going survey of various services to find out. Digital images, saved in the JPEG format support the embedding of photo metadata, and most social media sites support the uploading of JPEG images. However, many of these social media services do not preserve this information that you have taken the time to embed in your image files. In some instances this information is removed on upload; in other cases, it may preserved in the original uploaded file, but any images derived from the original may no longer retain that same information. Anyone downloading an image of yours for reference may not know where that image came from or who to contact, without at least some basic information remaining stored within the image file. Objective The objective of this survey is two fold. 1). 2). A. B. C.
Ajout des métadonnées à un article Les informations de métadonnées sont stockées à l’aide de la norme XMP (Extensible Metadata Platform) sur laquelle reposent Adobe Bridge, Adobe Illustrator, Adobe InDesign et Adobe Photoshop. XMP repose sur le format XML. Dans la plupart des cas, les métadonnées sont stockées dans le fichier. Lorsqu’il n’est pas possible de stocker les informations dans le fichier, les métadonnées sont conservées dans un fichier distinct appelé fichier annexe. Les métadonnées stockées dans d’autres formats, tels que Exif, IPTC (IIM), GPS ou TIFF, sont synchronisées et décrites à l’aide de la norme XMP pour faciliter leur visualisation et leur gestion. Dans la plupart des cas, les métadonnées sont conservées dans leur fichier, même si le format du fichier change (de PSD à JPG, par exemple).
Stock Artists' Alliance (Copyright Protection Member Org) Restoration of defocused and blurred images. Yuzhikov.com Restoration of distorted images is one of the most interesting and important problems of image processing - from the theoretical, as well as from the practical point of view. There are especial cases: blurring due to incorrect focus and blurring due to movement - and these very defects (which each of you knows very well, and which are very difficult to repair) were selected as the subject of this article. As for other image defects (noise, incorrect exposure, distortion), the humanity has learned how to correct them, any good photo editor has that tools. See the next part of this article here Why is there almost no means for correction of blurring and defocusing (except unsharp mask) - maybe it is impossible to do this at all? In fact, it is possible - development of a respective mathematical theory started approximately 70 years ago, but like other algorithms of image processing, deblurring algorithms became wide-used just recently. Let's start from afar. Then we run the script: Result:
File Formats and Preservation « Digital Preservation for Beginners File formats are the rock stars of digital preservation. After all, one of the goals of digital preservation is to prevent a loss of access to files due to file format obsolescence. If you are using a file format migration strategy for preservation, then you will be refreshing the digital files over time to keep the content stored in formats that are readable by the current technology. If you are practicing a software emulation strategy for preservation, then you are maintaining software that will be able to read the old file formats. When a digital object is deposited into a digital repository, the type of file that it is will be declared by its extension (.jpg, .pdf, etc.). Extinction Photo by Charles Tilford, CC license As you know, when a software program creates a file, the program can re-open the file to view it, edit it, etc. To illustrate this point, let’s look at the old Mac program MacPaint, which was a basic painting program that shipped with Apple computers from 1984-1988.
Découvrez la norme XMP (Extensible Metadata Platform) et apprenez à utiliser des métadonnées dans Adobe Bridge. Les informations de métadonnées sont stockées à l’aide de la norme XMP (Extensible Metadata Platform) sur laquelle reposent Adobe® Bridge, Adobe Illustrator®, Adobe InDesign® et Adobe Photoshop. Les réglages effectués sur les images avec Photoshop® Camera Raw sont stockés sous la forme de métadonnées XMP. XMP repose sur le format XML. Dans la plupart des cas, les métadonnées sont stockées dans le fichier. Lorsqu’il n’est pas possible de stocker les informations dans le fichier, les métadonnées sont conservées dans un fichier distinct appelé fichier annexe. XMP facilite les échanges de métadonnées entre les applications Adobe et les flux d’édition. Les métadonnées stockées dans d’autres formats, tels que Exif, IPTC (IIM), GPS ou TIFF, sont synchronisées et décrites à l’aide de la norme XMP pour faciliter leur visualisation et leur gestion. Dans la plupart des cas, les métadonnées sont conservées dans leur fichier, même si le format du fichier change (de PSD à JPG, par exemple).
Picture Licensing Universal System DigCCurr Conference 2009 Keynote| Papers| Panels| Tools and Demos| Posters Keynote Building the Universal Library: The Promise and Challenges of HathiTrust Wilkin, J.P. HathiTrust is a multi-institutional effort to create the universal library – to bring together as comprehensive a body of works as possible and to do it in a way that ensures access, permanence, content preservation, and an advanced environment for research. In short, HathiTrust is an effort born of libraries, working to bring the lasting contributions of libraries to bear on the growing body of digital materials available to students and researchers. Much has been said and written about the silo effect of digital libraries, the way that our early technological efforts Balkanized content and failed to capitalize on economies of scale.

How to Protect Your Images with Metadata There is little you can do to stop someone who is determined to steal your images. Watermarks are easily removed and website scripts are defeated with a simple screen grab. These attempts only mar your work and make your site difficult to navigate. In this tutorial I’m not talking about protection from image thiefs, I’m talking about protection from lost opportunities. This happens more often than you think; art directors are constantly grabbing images whenever and wherever they see them, but seldom have the time to organize them and make note of where they came from (they should really be using Evernote). Wouldn’t it be great if you could tuck your name, website and keywords and copyright information into every image to avoid this situation? Metadata is data about data—like the Created and Modified dates you see attached to every file on your computer. 1. 2. 3. 4. 5. 1. 2. 3. 4.
