Roman Pottery Bowl

To change the light direction, click the lightbulb button on the left of the viewer, and click and drag over the viewer with the mouse. Click the question mark button for more guidance on using the viewer.

Reflectance Transformation Imaging is particularly valuable for capturing objects that have surface decoration or texture in low relief. Being able to move the light source makes legends, images, and wear and tear clearly visible, making it possible to investigate details of even heavily-worn objects and inscriptions.

Roman bowl with normals visualisation

Normals visualisation creates a false colour image with each pixel’s ‘surface normal’ direction mapped to a colour palette - indicating which direction each surface is facing.

Roman bowl with specular enhancement

Specular enhancement mathematically increases the image contrast, exaggerating the surface texture depth of the item. In the RTI viewer software, this effect is overlaid over the interactive image, meaning the light source is still moveable.
