Visual feeling and Illumination
Hi everybody,
I am working on a project which tries to control illumination by controling the electrical power consumed by an electrical lamp (a form of dimmer). In a part of this project I need to discuss the relation between the change in the illumination with what the visual system senses. I know that there is a logarithmic relation in sound where dB is used to express the way our auditory system operate and feel but does a similar relation applies to visual system or is there any relation or curve relating the change in the illumination to the effect it has on the visual feeling. Can anybody introduce a web source or book on this? Many thanks for your help. Khashayar |
