The instructions below describe the workflow for the capture of Infrared-reflected images. Workflow for the capture of UV-reflected (UVR) images Equipment requirements: e Camera e UV radiation sources e UV bandpass filter (e.g. DUG 11X) e UV safety glasses e Macbeth colour chart (not required but remains in the shot from previous image for continuity) e Spectralon diffuse reflectance grey scale or any number of Spectralon diffuse reflectance standards as available. Set-up 1) Position the UV radiation sources and the camera as shown in Figure 2-28 and according to the recommendations in section b. | Object av v 5 Visible-blocking UV 31 & 3 UV filter (DUG 11X) Blue stray x jani 5 tj ¢ light v7 2 || Be £ SS DUG11X 917 ki 3 = — UV Lights 2\| & rs (Wood lights) 2 UV bandpass filter (e.g. DUG 11X) 2) Place the UV bandpass filter (e.g. DUG 11X) in front of the camera. 3) If working in the studio, position the object following the recommendations referred to in section b.
