The tape has a magnetic layer and contains organic binders. When the tape ages, or if it is exposed to humanity or moisture, these materials degrade and create an environment in which mould can grow! 📹📼

Once in a digital format, footage can be easily backed up, copied, edited, or restored. It becomes possible to correct colour issues, stabilize shaky video, or repair damaged audio

Even if tapes remain in good condition, the equipment needed to view them is disappearing as VHS players are no longer commonly manufactured and working units grow rarer. By converting to digital files, we free recordings from depending on obsolete technology and prevent their contents being lost

3D modelling allows us to create digital versions of physical objects. These can be made available for people to view and study, when the originals may be too fragile or valuable to be handled, or not available. Measurements and analysis can be carried out that would only be possible digitally

By taking images of a surface or object from different angles, software identifies common points and uses triangulation to reconstruct shape and scale. This results in outputs such as 3D models, point clouds, and detailed maps

Our interns were tasked with bringing in an object they wanted to explore the texture of. They learned how to appropriately position an artefact for the most accurate results, adjust the necessary photography settings & light sequencing, & process their photographs to create a final RTI model

The image can be enhanced to exaggerate the surface relief and provide a better view of key details. The normals visualisation technique creates a false colour view of the normals of reflection, indicating the direction each surface faces, and giving a better idea of the overall shape of the object.

Creating an RTI involves photographing a subject while varying lighting angles in a controlled manner. Spheres are included in the photographs to record the angle & enable the processing software to calculate a matrix of surface normals that indicate the direction of reflected light from the surface

Often referred to as 2 1/2- dimensional imaging, RTI can offer a superior view of surface relief and texture compared to conventional photography. It can produce views of marks, inscriptions, and indentations to assist with readability, and create a visually engaging experience of the object
