(Flat fielding)
. Camera output file — visible-reflected image
- ICC profile for conversion from RAW (contained within the image file)
- Image of uniform reflective board under experimental conditions for flat fielding
» Image of Macbeth chart for spectral density and colour calibration (included as part of the
image to be calibrated or another image taken with the same camera and lighting conditions)
- Image of Spectralon diffuse reflectance grey scale or any number of Spectralon diffuse
reflectance standards as available (included as part of the image to be calibrated or another
image taken with the same camera and lighting conditions)
All must be taken under identical illumination conditions and geometry
