We are meeting Thierry Dreyfus who is french, 45 years old. Thierry, tell us a little bit about yourself, what you do for a living and the way ou do it ?

TD : I have been doing light design for the last 25 years. I am working with the installation of lighting and illumination for fashion and luxury shows. This is what I do for a living ; that is what I live for.

Our magazine is focussed on how other people's lives can be "transformed". In the way you work with light, do you have any interest in beauty and make up ?

TD : Light is day-to-day life, what we call "white light", is used in medecine to cure depression. You can see that in most European cities, the light is yellow and quite depressing. In my next project at the Grand Palais in Paris, in september, I will be working in white light to give people emotion, to make them smile and to avoid being depressed. In the interior design concept, when you travel a lot from one hotel to another, and when you want to read, you become aware that very few architects have thought about the possibility of you reading alone without disturbing the other person or illuminating the whole room. They haven't thought either about a woman applying her make-up in the bathroom in the morning using a yellow light, but then walking out on the street and finding a blue light. The interior light is completely different from the light outside.

So a woman's make up looks diffrerent indoors from outdoors and therefore the way a woman perceives herself is not the same way as other people will see her ?

TD : if a woman would take the same mirror in her bathroom outside, she would definitely look different.
