Kept Art Restoration employs several non-invasive methods of examining and documenting cultural heritage artifacts.
Techniques such as HDR, RTI, ultraviolet and infrared imaging, polarized light imaging, raking light photography and more provide the conservator with a wealth of information useful for the initial condition survey, and for determining the appropriate courses of treatment – all without damaging the artifact in any way.
These images are used in the survey and treatment documentation we provide, and the source images can also be provided to clients directly for the benefit of research, appraisal or simple curiosity. Please take a look at an example pre-treatment report.
Infrared imaging and color processing clarifies details
Lighting treatments can exaggerate brushwork detail or damage
UV Fluorescence imaging can reveal hidden damage and prior restoration efforts
HDR photography allows details to be visible in context where traditional photography would be challenged.
RTI imaging uses computationally-intensive math to reveal details that would be impossible to see any other way.
