  1. We at CHI are thrilled to announce the release of the first two tools (Version 1 Beta) in a new software suite, the Digital Lab Notebook (DLN). DLN is a metadata toolkit designed to simplify the collection of standards-based metadata, essential to scientific imaging. The goal is widespread democratization of tools that worldwide cultural caretakers can deploy to digitally capture, build, archive, and reuse digital representations. We hope you will download and try out these new tools! DLN:CaptureContext With a user-friendly interface, this tool expedites and simplifies user input of metadata -- such as locations, institutions, imaging subjects, image rights -- with a template process. DLN:Inspector This tool automatically ensures that each image set meets the requirements for high-quality computational photography imaging, checking for image-processing errors, such as sharpening, that should not be applied to photogrammetry or RTI image data. Instructional Videos for DLN See our new Vimeo channel -- Simplifying Scientific Imaging -- where we have posted an instructional video series about the DLN, what it does, how to use the software tools, and more.
  2. Cultural Heritage Imaging (CHI) offers some free resources to people adopting the practice of photogrammetry. In addition, our experts are available for paid consulting and/or training. Here are some resources not to be missed. 1. Videos describing key principles of good photogrammetric capture: https://vimeo.com/channels/practicalphotogrammetry See also our Photogrammetry technology overview: http://culturalheritageimaging.org/Technologies/Photogrammetry/ 2. This, our free user forum, where folks in the community help answer questions about RTI and photogrammetry. We aim to complement the resources offered by Agisoft PhotoScan and other software packages, as they have their own communities. However, discussions about equipment, capture tips, and so on are welcome here: http://forums.culturalheritageimaging.org/ 3. We sell calibrated scale bars that help users get precise, real-world measurement into your product. And we offer a "tips and tricks" free guide for working with scale bars on the Photoscan website (find the link on this page): http://culturalheritageimaging.org/What_We_Offer/Gear/Scale_Bars/index.html 4. We offer regular 4-day training classes in photogrammetry in our studio in San Francisco and in other locations. Sometimes a host institution will offer space and will purchase some seats and allow some seats to be sold. You can learn more about our photogrammetry training here: http://culturalheritageimaging.org/What_We_Offer/Training/photogram_training/index.html 5. And finally, we offer custom consulting to help folks adopt and use photogrammetry and RTI. That can take a variety of forms, including video, emails, and projects in Dropbox where we can review work and give feedback. Learn more about our consulting offering here: http://culturalheritageimaging.org/What_We_Offer/Consulting/
  3. We've discovered the links to the videos that were taken at The Met (2-day symposium in March 7-8, 2017) are not working. Please bear with us - we will contact our associate at the museum to find a way to reconnect to these videos.
  4. CHI is delighted to announce that all the recorded talks from our NEH-sponsored symposium at The Met last March -- "Illumination of Material Culture: A Symposium on Computational Photography and Reflectance Transformation Imaging (RTI)" -- are available now from the museum website: https://www.metmuseum.org/about-the-met/conservation-and-scientific-research/projects/rti-symposium/ These talks by worldwide experts share the latest research and use cases in the application of Reflectance Transformation Imaging (RTI) and related topics in computational photography. Enjoy!
  5. CHI Director Carla Schroer will present a short course and a paper at the IS&T Archiving conference in Riga, Latvia in May. In the short course (May 15), she will offer a condensed overview of computational photography and its application to cultural heritage, describing techniques that are being applied to a variety of art objects and other examples of material culture. There are no prerequisites — anyone from novice to expert is welcome. In the talk (May 17), she will present the first module of an advanced set of metadata and knowledge management tools to record a “Digital Lab Notebook” (DLN), the equivalent of the traditional scientist’s lab notebook. Get more details at http://culturalheritageimaging.org/What_We_Do/Events/index.html#ist_2017
  6. CHI has updated its Photogrammetry technology web page with detailed, careful instructions and images that explain about how to capture photos properly for photogrammetry. Also on the page is an added example: an embedded interactive 3D model of an Assyrian genie bas relief, hosted on Sketchfab. The imaging was done as part of a National Endowment for the Humanities (NEH) sponsored training session, hosted by the Los Angeles County Museum of Art (LACMA). See the updated "How to Capture" area of the web page with the Sketchfab example below.
  7. Don't miss CHI's next 4-day photogrammetry class in the fall: Monday, September 25 through Thursday, September 28, 2017 These classes have limited seating and tend to sell out, so please don't hesitate too long to register. You will find the reg form and other information about the class at this link: http://culturalheritageimaging.org/What_We_Offer/Training/photogram_training/index.html We hope you can join us!
  8. The US Bureau of Land Management has updated its link to the well-known Tech Note 248 (a downloadable PDF) by Neffra Matthews and Tom Noble: https://www.blm.gov/nstc/library/pdf/TN428.pdf CHI has updated the link on our Photogrammetry technology page on our website: http://culturalheritageimaging.org/Technologies/Photogrammetry/
  9. Hello everyone, After almost 3 years of selling the RTI starter kits for $350, CHI must raise the price to $370 to cover cost increases for many of the parts. We will sell our current stock on hand at the $350 price (we have just a couple of kits left), after which the price will go up.
  10. Seeing this exchange about archiving RTI data highlights for me what is surely one of the most intriguing and strategic projects at CHI: the Digital Lab Notebook (DLN). The DLN is designed to serve the same function as a written scientist’s lab notebook before the digital age. In its simplest form, the DLN is a record of the means used to digitally capture information about something -- let's say, a cultural object -- including the history of events associated with the object's capture and subsequent processing. Finally the result is a completed digital representation of that object that is accessible, transparent, and empirically verifiable. CHI is now developing its next generation of software tools that will generate digital lab notebooks containing Linked Open Data with advanced knowledge management features. CHI's methodologies, capture, and processing tools are designed to collect all of the information necessary for a scientific lab notebook. I suggest anyone interested in the vision for DLN to take a look at CHI's description of it here: http://culturalherit...k/more_dln.html
  11. CHI is delighted to make this new free forum available, and we're grateful to the Institute of Museum and Library Services (IMLS) for our 21st Century Museum Professionals grant, as we used a little bit of that funding to get the forums going. When you sign up for this free forum, you are joining the growing community of Reflectance Transformation Imaging (RTI) users all over the world. In recent years, new RTI tools, methods, and uses have emerged, and the list is expanding all the time. Let this forum be your learning center: How are museum conservators, computer scientists, natural scientists, photographers, and other related professional groups using RTI? What problems are they solving? What challenges are you encountering in your own RTI projects? You and your colleagues can use this forum to share your questions, insights, and issues to gain a more complete understanding of the technology and its practical applications. This conversation is for you!
