The result is that many lighting companies’ marketing photos show brightly lit spaces and the actual luminaire is a bright ‘sunburst of light’ and impossible to see. The photographer has attempted to make it look well lit and demonstrate how the lighting has improved the scene being photographed, but as a lighting manufacturer or designer you will want to show a number of additional features in addition to a well illuminated room. You will want to show the aesthetics of the luminaire, perhaps that there is little or no glare and how well colours are reproduced under the artificial light.
Similarly when there are several different light sources with different colour temperatures, the eye is very good at detecting these differences and noticing the subtle changes in colour. For a camera it is more difficult. The accurate representation of colours is largely determined by the white balance setting. Cameras are calibrated to a standard mid-grey and they assume that most photographs have an average scene colour that is grey. Consequently a scene containing a lot of white or alternatively a lot of black will result in the camera sensor reproducing the colours inaccurately.
