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

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 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.

Photography is a major force in explaining man to man.

The other great development has been in photography, but that too was influenced by Conceptual art.

I had done a lot of rock 'n' roll photography when I was in college. I was one of many photographers who worked for The Doors, Jefferson Airplane, and all of these rock 'n' roll bands.

In 1979, I received a phone call from Ansel Adams asking me if I would be willing to consider coming to work for him. I was teaching photography in Southern California at that point.

So when I became interested in photography and further being inspired by the work that I saw of Ansel and others, it was a natural extension to go back to these places that I knew as a kid and explore them with my camera.

It is my intention to present - through the medium of photography - intuitive observations of the natural world which may have meaning to the spectators.

Actually, I'm not all that interested in the subject of photography. Once the picture is in the box, I'm not all that interested in what happens next. Hunters, after all, aren't cooks.

The clue to book jacket photography is to look friendly and approachable, but not too glamorous.

It takes a lot of imagination to be a good photographer. You need less imagination to be a painter because you can invent things. But in photography everything is so ordinary; it takes a lot of looking before you learn to see the extraordinary.

There is only you and your camera. The limitations in your photography are in yourself, for what we see is what we are.

Those involved in the program are interested in how to use photography, videos, the Internet, film, and anything related to communications and transmission of information in the most up-to-date modern ways.

Music is the doorway that has led me to drawing, photography, and writing.

Videos are more like photography. It's not as much about trying to tell a story as it is creating images.

My interest in architecture has always been sculptural. Most of my photography is of architecture.

As an avid photographer, I also took advantage of the latest technology in photography - digital photography - to post photos on my website on a daily basis.

But slowly I began to use cameras and then think about what it was that was going on. It took me a long time, I mean I actually played with cameras and photography for about 20 years.

Look at lots of exhibitions and books, and don't get hung up on cameras and technical things. Photography is about images.

I love photography. My boyfriend's got a great camera, which I bought for his birthday.

My use of the medium - photography - is in some ways traditional.

Few speeches which have produced an electrical effect on an audience can bear the colourless photography of a printed record.

Now, my knowledge of photography was terribly limited.

Photography suits the temper of this age - of active bodies and minds. It is a perfect medium for one whose mind is teeming with ideas, imagery, for a prolific worker who would be slowed down by painting or sculpting, for one who sees quickly and acts decisively, accurately.

The use of the term art medium is, to say the least, misleading, for it is the artist that creates a work of art not the medium. It is the artist in photography that gives form to content by a distillation of ideas, thought, experience, insight and understanding.

Photography is an immediate reaction, drawing is a meditation.

A lot of people think that when you have grand scenery, such as you have in Yosemite, that photography must be easy.

The problem for me is that I've never actually studied photography, so it's quite a steep learning curve. Cameras these days do so much for you automatically but I still think there's a point where you should actually know the technical side.

I was an artistic dilettante for a while, in photography and collage and the visual arts.

Any time you talk about the look of the film, it's not just the director and the director of photography. You have to include the costume designer and the production designer.

Photography is truth. The cinema is truth twenty-four times per second.

My son does a little photography, but he's not involved the way I was.

In the world of photography, you get to share a captured moment with other people.

I don't think that digital photography is romantic yet. It's not sympathetic the way that film is.

It's the first time that I've ever had an art show based on a film, but it's a photography collage.

Photography to me is catching a moment which is passing, and which is true.

I think landscape photography in general is somewhat undervalued.

I open events for museums and I do charity work and photography.
