Abstract
A method is provided of determining a device spectral response for an image recording device. The method comprises obtaining a filtered light response from a number of filters of a filter set, wherein each filter has a pass band with at least one boundary defined by a transition region. In the wavelength region of interest adjacent transition regions of the same sense are substantially non-overlapping. The obtained filtered light response for each filter is stored as response data. The device spectral response is determined using the stored response data and separately determined data describing the spectral response of the number of filters.
