Kept Art Restoration employs several non-invasive methods of examining and documenting cultural heritage artifacts:

High-dynamic-range imaging (HDR)

Reflectance transformation imaging (RTI) 

Ultraviolet (UV) and infrared imaging (IR)

Polarized light imaging (PLI)

Raking light photography (RAK)


RTI imaging uses computationally-intensive math to reveal details that would be impossible to see any other way.

HDR photography allows details to be visible in context where traditional photography would be challenged.

These methods provide information used in the initial condition survey and in determining the best suited treatment plan. More importantly, using one or more of these methods ensures no damage to the artifact throughout the repair process.

These images used in the survey and treatment are available to clients directly, for research, appraisal or simple curiosity.
