During exposure, interference takes place between the incident rays and those reflected by the mirror, with the formation of interference fringes half a wavelength distant from each other.

The plate at each point only sends back to the eye the simple colour imprinted. The other colours are destroyed by interference. The eye thus perceives at each point the constituent colour of the image.

The problem of direct colour photography has been facing us since the turn of the last century.

The series of photographic operations, developing, washing, final drying, takes about quarter of an hour.

In the case of composite colour, an infinity of systems must be obtained for maxima infinitely slight and with an infinity of interval values separating them - that is to say, the whole thickness of the sensitive layer is occupied in continuous manner by these maxima.

During exposure, interference takes place between the incident rays and those reflected by the mirror, with the formation of interference fringes half a wavelength distant from each other.

The length of exposure (one minute in sunlight) is still too long for the portrait. It was fifteen minutes when I first began my work. Progress may continue.

When the shot is afterwards subjected to white light, colour appears because of selective reflection.

Most of these pictures, taken while travelling, were developed on the mantelpiece of a hotel room, which proves that the method is easy enough to carry out.

I got quite good results from protein plates.

This result is due to a phenomenon of interference which occurs within the sensitive layer.

Doubts are good. Confusion is excellent. Questions are awesome. All these are attempts to expand the wisdom of mind.

It's not a struggle, but sometimes when you're gone for a month or two, you start to miss your friends. I love acting so much that it fills that gap of being sad about not being able to see my friends.

People have always been obsessed by celebrities. There are just more outlets and opportunities to make a living exploiting that obsession nowadays.

There were various turning points, but the main one at the beginning was that I was going off to do another degree in the history of art. I would have ended up as some art historian at Sotheby's or something.
