Film Age

(All depends on which you prefere chemistry or physics)

The hundred years old story of using film in cameras has become to the last act but the show goes on. Next play will tell the story of digital photography and digital processing of a picture. I am neither a futurologist nor Nostradamus but I can see and I am able to turn my eyes........ One hundred years of R&D and all the great inventions in vein? Huge amount of capital and enormous capacity of human brains used for nothing?

Definitely not. During these passed decades photography has become a part of human life. I has achieved an essential role in media, in art, science and even in trivia. Only the sheets and ribbons coated with light sensitive materials, which are beamed down to history. Achievements of this era are despite the fact unchangeable.

Somebody could say that you see what you want to see and manipulating pictures is today easy as children's play. Too true, but making changes has at least two sides. Genetic engineering is manipulating and the aim could be good or bad. Things have never been unchangeable and today photography is in the state of change.

A little study of history attests that people that has been against changes has mainly been in the wrong. At the very least they have not succeeded to stop the caravan.

B/W film is made from light sensitive silver bromide crystals suspended in a gelatine emulsion and coated onto a plastic backing. Tell me what are the essential differences between silver bromide crystals and the digital CCD (Charged Coupled Device) or CMOS ( Complementary Metal Oxide Semiconductor) image sensors?

I admit that there is a long way to that over 80 million pixels (in theory) of Fuji Velvia 50 but the gap is decreasing day by day. The sharpness is certainly a basis for a good picture. . But at an important point, pictures don't improve with pixels. "The photographer takes the picture and camera is only a tool for that".

Color film has for years held as the standard for photography. It produces an incredible color detail that consumers have become accustomed to. Film has achieved this by using three layers of emulsion to capture full color at every point in the image. To day, the tones and detail of color film that the people came to expect is suffered over the convenience of digital.

Many photographers who swear on the film accept digital processing of the photographs. Why not record them digitally straight from the beginning? I know that some are strictly against any kind of manipulation but digital photography never means manipulation and manipulation is not a phenomenon born besides the digital cameras. I remember toners, various photo papers, shadowing and all other gimmicks to get pictures look different. Isn't that manipulation?

In 1972 Texas Instruments patented a film-less electronic camera and in August 1981, Sony released the Sony Mavica electronic still camera. To reach the quality of a film, digital cameras have still over seventy years time to advance. And they do, Foveon X3 direct image sensor is a good example towards the features of the photographic film. It has partially the same idea “doing” the picture like a modern color film. Perhaps it is not the solution, but we shall see and don't worry about megapixels just be patient. The rapid advances in digital technology, a future where digital photo quality rivals that of film is probably not too far away.  A minor conceding if it is a case of really big images feel free and use sheet films another ten years.

The major procedures of film processing are developing and fixing. Developing is to convert the latent image into an image. Exact reproduction of all colors might be not possible, although some films do rather better than others. Colors are represented using yellow, magenta and cyan. CCD image sensor records red, green and blue light and the rest of the spectrum forms in our eyes. Thus we can say that the picture develops inside the electronic circuits and then it will be fixed and stored in memory sticks.

Accurate colour is not always preferred, and so manufacturers have tended to give photographers some choice in how their pictures should look by providing alternative color materials. Digital cameras have revolutionized the world of photography. Now anyone with a digital camera, PC and printer has the equivalent of a darkroom and photo lab in their own home. Many effects that in the past were made with various filters are to day possible to do afterwards with picture processing software. We don't anymore use pigeons to send a letter nor a tinderbox to light a fire because better means are invented.

It comes to my mind an invention before the round wheel: Carriages were extremely inconvenient those days with they quadrangular cartwheels, bump after a bump after a bump. One zealous inventor proposed his revolutionary idea. Let's make them triangular, that means one bump less on every rotation.
