Colour is the most important feature for ornamentals, but unfortunately camera's can differ significantly in their colour reproduction ability. There is no garantuee that the colour of images of a new camera can be compared with existing images.
Therefore, we have used a more physical approach to colour. We have recorded spectroscopic reflectance images of the rose flowers, using a so-called imaging spectrograph.
From the spectroscopic reflectance image, we can reconstruct a colour image under any defined light source, for true colour measurements.
