The ability to show visual aids to photographers, whether of various materials such as stone, ceramic and metal, or living materials such as bone and plants , is important in the field of anthropology and archeology. For researchers, educators, students and the general public, the ability to see the past, not just by reading about it, provides valuable insights in making the cultures and the people who made and used them.

Photography is the most common method used for visual presentation, but despite its speed and quality, it often does not accurately reflect the person being trained. In recent years, 3D viewing has emerged as an alternative source of high -end models, but the cost of equipment and the time it takes to create a model is often fixed.

Now, a paper is printed on PLOS SOMEONE Two new ways to create high -resolution images of small photographs, each available with software and hardware. Using knowledge from schools related to archaeological science, computer graphics and the development of video games, ways have been developed that allow one to create images and features. high with low effort and cost.

The first approach, small -scale digital image processing, or SOAP, deals with the image application of new digital technologies. The protocol guides users through small -scale and graphic images from the initial setup of the equipment to the most efficient ways to use the hardware and software. using post -editing software.

The second method, digital image processing, or HRP, is used for image processing, digital reproduction and comparison of small objects. This approach is intended to provide a comprehensive guide to the development of high -quality 3D models, integrating popular technologies used in art and computer science schools, allowing anyone to work independently in high -quality and quantifiable features.

“These new protocols combine precise, concise, and user -friendly features that cover image processing and transmission, and then provide replicability and reproducibility of high -quality features,” he said. and Jacopo Niccolò Cerasoni, the paper’s original author. “By clearly defining each step of the process, thoughtfully and thoughtfully, these features will allow users to create high -quality, two- or three -way prints. -dimensional of their independent archaeological artifacts. “

The SOAP and HRP protocols were developed using Adobe Camera Raw, Adobe Photoshop, RawDigger, DxO Photolab, and RealityCapture and utilized real -time processes and tools to make image capture easier and faster. While most of these programs can be found in educational environments, SOAP and HRP can be used in other non -established programs with similar features. This allows researchers to use free or open source software, even with minor changes to some of the levels reported.

The SOAP protocol and the HRP protocol are widely published in

“Because it is important to have an eyewitness account of understanding the nature of the past, technology and culture, the ability to accurately present images is critical to the field of archeology. , “says historian Felipe do Nascimento Rodrigues, from the University of Exeter.

While new technologies are changing the field of archeology, there is no comprehensive study of archaeological images and three-dimensional innovations. The authors of the new paper hope to fill in this gap, providing researchers, educators and enthusiasts with advice at every step of the way for creating high -quality images of images. .
