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.

Life is short and progress is slow.

When California was wild, it was the floweriest part of the continent.

I have said repeatedly that the way to sustainable growth is to bring down inflation to much more reasonable levels.

Wall Street has become a veritable casino.

I believe wealth should be in the hands of those who know how to create more wealth.

I had hoped that he has mouth smell or something other repelling, but nothing! It was even charming.

We are different people - you get a different take on the band whoever you speak to. Somehow, at the end of it, it goes through the filtering process and out comes the Radiohead thing.

There's no time like the present

It's impossible to explain to people who you are in a five-minute interview on TV.

Every faculty and virtue I possess can be used as an instrument with which to worry myself.

Morning is an important time of day because how you spend your morning can often tell you what kind of day you are going to have.

Both my parents loved words. That was the big deal in our house.

Harvard, Yale, Princeton, and the rest of the Ivy League are worthy institutions, to be sure, but they're not known for educating large numbers of poor young people.

An enchanted love, an awakened love, between two people is a blessing on the entire world.

You're only dealing with whatever you know, which is a very small part of it and later on it'll look like it has something to do with the period. Obviously, the artists have something to do with one another. They tend to set up certain common qualities among themselves.

I've always wanted to explore different types of roles and prove to others that Divyanka is not all about being a timid dulhan.

Robert Zemeckis is a genius filmmaker who is an amazing individual. I feel really blessed that I've gotten to work with him on many different occasions.

We must believe what is good and true about the prophets, that they were sages, that they did understand what proceeded from their mouths, and that they bore prudence on their lips.

If most of us remain ignorant of ourselves, it is because self-knowledge is painful and we prefer the pleasures of illusion.

Almost anything is possible with time.

I'm a studio rat. I like going in there as producer.

The question of free will is insoluble on strictly psychological grounds.

I'm very shy really. I spend a lot of time in my room alone reading or writing or watching television.

Change begins with understanding and understanding begins by identifying oneself with another person: in a word, empathy. The arts enable us to put ourselves in the minds, eyes, ears and hearts of other human beings.
