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

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.

Life is short and progress is slow.

The factor most ignored in discussing interstellar flight is the kinetic energy that must be invested in the ship to make its tons of matter move at a substantial fraction of the speed of light.

When I came to New York and I opened the window of the thirty-fifth-floor apartment, there's light pollution and fog, and I couldn't see my star. So I drew it on my wrist with a pen, but it kept washing away. Then I went to a tattoo parlor on Second Avenue and had it done.

And my real enemy is not to hold the specimen sterile, but it's the lighting. The light is our real enemy. So we have to work with very very poor lighting. But we can increase the light with computers.
