Purpose of Non-Destructive Testing and Instrumental Analysis
- To safely identify the chemical nature of the photographic matrix prior to storage, treatment, travel, or for scholarly research expanding the professional knowledge of culturally significant and historic photographic materials.
- Minimize changes in the image, binder, and support from a better understanding of physical and chemical make-up of the photographic matrix.
Factors to Consider Before Examining and Testing
- Sampling on originals should be avoided or strongly limited to the strictly necessary (exception).
- Carefully consider the need for examination and testing. Avoid unnecessary testing.
- Obtain permission from the owner, curator, or authorized agent prior to examining or testing.
- Select the most appropriate examination or testing technique(s) that cover the needs.
- Analyzing equipment often will be ‘static’ and the object has to be brought to the equipment. Consider a good packing and transport of the object will be required.
- The object size can be restrictive by the selection of the examination or testing technique(s).
- The examination location(s) should be representative for the given photographic object or different areas should be selected.
- This areas should be free of extraneous materials or previous treatments. Areas showing deterioration or injury may respond differently.
- Nearly all photographic materials can be considered as modern materials and often are composed out of many different kinds and types of materials. Testing of all the components of the photographic material can be required.
- It is always useful to have a reference, control and/or blank sample simultaneously tested to judge the effect or the response of the test.
- Judgement of the obtained results often requires experience and the use of controls.
- The examination or test conditions should be documented well to make repeated or similar testing possible.
Effects of Examining and Testing on Photographic Materials
- The examination and testing techniques should be safe and are considered being non-destructive. If during examination or testing alterations should become visible, testing should be stopped immediately.
- Limit the duration an object or a certain area of it will be exposed to the testing conditions or environment, to the strict minimum. Examination or testing equipment should be set-up and calibrated in advance.
- Local testing can create local staining or (temporary) local planar deformation of the support or binding medium.
- Some non-destructive testing methods can create temporary local physical changes of the substrate and or binding medium.
Techniques for Non-Destructive Analysis
- Micro-fade Testing
- Reflectance Transformation Imaging (RTI)
- X-Ray Fluorescence (XRF)
- XRF spectroscopy is used to identify inorganic components in photographs. This is valuable for determining image forming metals, toners, additives, paper components and additional layers.
- This technique cannot identify organic components of the photograph including binder layers, carbon-based pigments and paper fiber content.
- X-Ray Diffraction (XRD)
XRF Spectra of a Gelatin Silver Print
XRF Spectra of a Selenium-toned Gelatin Silver Print
Infrared (IR) Imaging
Micro fade testing (slightly destructive)
- Optical Microscope
- Scanning Electron Microscope (SEM)
UVA/Visible Fluorescence of a Hand-colored Photograph
- UV induced visible fluorescence
- UVA: Examination and imaging of UVA/visible fluorescence can provide information that is difficult to see in normal light examination. Some examples:
- Optical brightening agents
- Previous treatment
- Mold growth
- Hand applied pigments
- Pigments used in the photographic process (dye transfer prints, etc.)
