I participated in a recent 4-day RTI workshop with CHI at their SF lab on behalf of my museum. We will be using RTI to support research on a global collection across a wide range of objects, from ancient coins to contemporary prints. The small size of the workshop group of 5 was great; we got tons of hands-on practice shooting small and large objects with vertical and horizontal setups. Mornings were given over to training and lecture in one of four areas (capture, processing, viewing + dissemination, and current research on/with RTI), and afternoons were for practice. In a typical afternoon, we would be able to setup and capture 1-2 objects in small teams, and then process and view the RTIs. Because CHI had multiple camera setups and loads of equipment for us to play with, we got to work in pairs and experiment with different equipment, different objects and materials (coins, boxes, masks, prints), and different setups each day. I came away from the training understanding not only the process but the underlying concepts of RTI and completely prepared to come back to my institution, begin using the technique right away, and train others in it as well. I would (and will) recommend CHI to my colleagues, and will hope to be able to come back for photogrammetry training.
CHI's 4-day RTI training was exemplary in every way. The combination of lecture and hands-on experience was ideal for learning a new skill that is both conceptual and practical. Carla, Mark, and Merlin are all incredibly knowledgable and generous with their time and insights. Given the small class size (5 total), instruction was tailored to fit my individual interests, maximizing opportunities to practice capturing, processing, and viewing images like those I intend to generate as part of my doctoral research. As an art history student, computational photography training is hard to come by, and these four days have already proven to be absolutely essential for my current project and professional ambitions.
I was not familiar with CHI until recently, when I attended a week-long workshop on photogrammetry. As a beginner in this technical area of cultural heritage, I could have felt overwhelmed but the CHI experts guided us all through the information at the level that suited each of our skill levels. I'm looking forwarding to putting the training into practice! I must also say that it is always great to learn from the experts who are not only up-to-date on the current practice but are pushing the envelope forwarding and innovating the field.
Cultural Heritage Imaging (CHI) has been an incredible help to me in my career as a digital humanist. I first encountered them when I used their documentation, program, and supply kit to carry out Reflectance Transformation Imaging while on a Fulbright fellowship in Athens, Greece. Their materials and instructions were comprehensive and clear, and enabled me to create digital records of stone inscriptions of a quality previously only rivaled by paper negatives (i.e. squeezes) or charcoal rubbings, both of which processes can harm the stone.
I subsequently undertook a week-long intensive training class in photogrammetry with CHI at their headquarters in San Francisco. Carla, Mark, and Marlin were all wonderful teachers, and I not only had a wonderful time and made some lasting and important contacts in my field, I also walked away able to implement the technique by myself and even teach it to colleagues. Indeed, I returned to Athens to carry out photogrammetry at the Museum of the Ancient Agora, and later presented the results of my RTI and photogrammetry work on inscriptions at a conference held at the Institute for Advanced Study in Princeton, NJ.
In March of 2017, I attended a symposium organized by CHI at the Metropolitan Museum of Art in New York City. There, in addition to renewing my previous contacts and making even more, I also saw a presentation about how to build a dome to carry out RTI. With a colleague from Rutgers University, I built a dome to image some of the coins from the Badian Coin Collection in the Rutgers Libraries, and for our project we were recognized with an award from the New York City Digital Humanities group.
Everyone at CHI has always been exceptionally helpful and friendly, and I really could not think of a group more important in my movement from traditional classical philologist to digital humanist. I cannot recommend enough their products and services!
Last fall I attended a four-day workshop on scientific photogrammetry for cultural heritage put on by the staff of Cultural Heritage Imaging and I cannot stress enough how impressed I was with them and with the whole experience. I came into the workshop with high appreciation of but pretty minimal personal familiarity with photogrammetric techniques and left having been taught an incredible amount information, giving me the best possible basis for growing my own expertise. They were organized, thoughtful, thorough, and careful in their instruction, whether discussing broad backgrounds and philosophies of photogrammetry or the nuances of specific techniques. CHI is passionate about making these important and accessible to cultural heritage and educational institutions and are committed to ensuring that practitioners do it *right* so that results have scientific value and serve the mission of our organizations. Their deep familiarity with technologies, techniques, and cultural heritage practices meant that they were ready to answer any question we sent their way. A wonderful and helpful group of true professionals. I could not recommend them more highly.
I recently took a workshop in photogrammetry through CHI. It was something totally new me, to use in my Conservation photography.The instructors had much enthusiasm and knowledge in their field ,each with their own expertise to share with us ! We all got to work in groups to photograph art objects and then produce 3D images in the computer - Photoscan program with CHI's help ,a printed booklet and talks that were given.
I've attended the course on Photogrammetry for scientific imaging by CHI last September. I was very impressed by their professional and scientific approach to imaging, with a strong focus on attaining repeatable and true to life photogrammetry data, as opposed to generating mere pretty models of the artefacts.
The level of competence demonstrated by the staff throughout the four days was amazing. The lectures, hands-on sessions, and the manual all complemented each other to allow the trainees to quickly develop the basic skills needed and to carry on improving on a self-taught basis.
I have been working in Cultural Heritage for many years and the kind of training provided by CHI covers (and exceeds) all the basic criteria I would expect from a course of this kind. Highly recommended.
I recently had the opportunity to attend a CHI training course on photogrammetry. I learned more in the four days with them than I had trying to learn the process by myself over the last two years. I fully support their mission to bring novel technological/preservation skills to heritage professionals and the public through their outreach and education. They are focused, passionate, engaging folks who are making a marked impact on the capabilities of those who are able to attend their workshops. I feel I cannot overstate that last sentiment enough: CHI is doing their part to help usher in the future of cultural heritage preservation and public engagement for our shared, irreplaceable cultural resources. While many in the class I attended came from a museum or a curations background, I was there to find new ways to apply photogrammetry to archaeological research. The instructors often took time to address my specific questions about field applications and throughout the workshop would think of ways I could utilize the methods being taught in the types of environment I am likely to encounter.
I highly recommend the CHI team and their work. I look forward to learning more with them in the future.
CHI provides an invaluable course in photogrammetry for anyone involved in Cultural Heritage. I would recommend their course to any photographer as an absolute must if your institution is looking to get into photogrammetry. The hands on training, the peer learning, and the materials you will have once completing the course should be in everyones desk.
CHI's training courses exceed expectations. They value the importance of hands on experience which is critical for retention of these complex imaging modalities. They teach methods that promote scientific integrity which is imperative when adopting to a proper cultural heritage institution workflow. I learned much more than expected and have no doubt in my ability to successfully integrate these processes into my own professional workflow.
CHI offers in depth yet accessible training in computational imaging. Their staff clearly holds true passion towards advancing the field and teaching others. I highly recommend taking one of their training courses to anyone associated with the cultural heritage field.
CHI is an amazing organization that functions in the truest sense of a non-profit. Their focus is on sharing their knowledge, educating the cultural heritage community, and developing open source tools to help that community thrive!
Cultural Heritage Imaging (CHI) has made an enormous knowledge contribution to the museum community. Scientifically accurate 3-D imaging is rapidly becoming a core methodology serving conservators, scholars, preservationists, and casual learners. The current rapid expansion of 3-D photogrammetry for documentation of cultural heritage collections is largely due to the trainings conducted by CHI, both at their own facility and remotely at institutions worldwide. In addition to formal training the CHI team freely share their sophisticated refinement of the photogrammetry process through participation in conferences, workshops and museum community listserves. In my opinion those responsible for imaging of many of the world's most significant cultural heritage collections would not be capturing quality 3D image data without the research, dedication, and spirit of openness that CHI provides.
CHI has for years and years engaged with both the cultural heritage professionals they serve and the academic communities that invent the new technologies they use. Their training programs are often backed by grants that they received jointly with universities. Why does this matter? They are constantly challenged by expert researchers on the technical side as well as the arts and humanities side. In my work with them I have found them to be extremely competent at what they do.
One of the best and most dedicated non-profits in the cultural heritage field I have ever encountered. They go above and beyond with every project they tackle and their philosophy about sharing their knowledge and data with the public is amazing. Truly a heart-warming experience working with them-could not recommend them more!
Our department has collaborated with CHI on Reflectance Transformation Imaging (RTI) for the past six years. Carla, Mark, and Marlin are leaders in the field and have been instrumental in making RTI and related technologies accessible within the cultural heritage sphere. Their training sessions impart practical knowledge and their countless lectures at conferences around the world propel the intellectual discussion forward. Additionally, the resources they have made freely available through their website have helped us to maintain best practices long after our training had concluded. Their work truly enriches the field.
Cultural Heritage Imaging are leaders in their field. Or to be more precise, CHI are the only ones in their field, and they're bringing all of us forward with them.
CHI are helping museums, archaeologists, and cultural heritage organizations move forward with digitizing and sharing cultural heritage objects from around the world. They're offering trainings in both Reflectance Transformation Imaging (RTI) and photogrammetry, and they're teaching the capture technologies to photographers and non-photographers alike.
I've taken both the photogrammetry and the RTI trainings from CHI, and both have exceeded my expectations. Now I can share my knowledge with my museum and with colleagues at other museums, and we have more ways to document and share the objects in our collections.
CHI has been, and continues to be a great source of Technical instruction, know-how and support for evolving and far reaching imaging. Other reviews have said it well; take a look at the institutions and experts they have worked with. That is a testament to their work. What I can add is how the team at Chi put their passion into keeping these imaging technologies moving forward in an open source environment is a significant asset to the Cultural Heritage Imaging Community worldwide.
I have had the great privilege of collaborating, learning and building a professional relationship with the Cultural Heritage Imaging group (CHI) for close to ten years. Their founders Carla, Mark and Marlin are as committed as ever to the development and dissemination of imaging techniques that empower cultural heritage documentarians and caretakers all over the word, with low cost equipment and techniques. As the Senior Conservation Photographer at the largest encyclopedic collection on the West Cost, under LACMA's Conservation Center, I can attest to the importance of CHI's work. Abiding by a strict scientific approach and a philosophy of open-source sharing, CHI is always looking forward. They have come a long way with the development and dissemination of Reflectance Transformation Imaging (RTI) and now, Photogrammetry, but they never lose sight of the future. Their teachings are grounded in very strong fundamentals that allow for the generation of documentation (data-sets) with longevity. These best practices allow institutions, collections and archives, to rework currently acquired information to a higher degree of processing as soon as the technology and algorithms become available. Proof of the important work that CHI performs are the numerous grants that they have been awarded throughout the years, institutions of great weight like the IMLS and NEH have contributed to their efforts with consistency attesting to the influence that they have in the Cultural Heritage field. I know that supporting CHI in anyway is supporting the development of accurate and reliable techniques and procedures to document cultural heritage artifacts and sites anywhere. Lately with the current political climate in many regions of the world this resonates with great importance and a sense of urgency to safeguard, at least in a digital format, cultural landmarks that are under constant threat. We need organizations like CHI to succeed if we want to preserve our human collective memory and history.
I work with CHI as a technical writer, which gives me a chance to see how the technology has been developing and expanding. It is fascinating to see how it can be applied in such widely disparate fields.
I also love getting to work directly with this great team. They really know their stuff, and know how to get it across to people. It is satisfying to see our work getting into the hands of the people that need it and appreciate it.
