Photography has come a long way since the invention of the daguerreotype and Calotypes. Photographic Prints are also important for photography as the camera. You can have the camera technology, but if you can take a photo paper, you can not see how the picture came out. Although, with the advent of digital cameras, the use of photographic prints have been taken to the verge of becoming obsolete. The Daguerreotype involved the use of silver leaf and a positive image was fixed on top of the sheet metal. William Henry Fox Talbot was the man responsible for making a step forward by using a negative by which multiple prints could be made. Around 1856, Hamilton Smith, has patented a process called Tintypes. The process uses a thin sheet of iron as a basis for creating a positive image. In 1889 he was made easier by George Eastman, who made the real market potential of photography. He released a film that had a flexible base material easy. The emulsion coated film base of cellulose nitrate made the process easier to take pictures. Now photographers could carry cameras in their box without worrying about big plates and bulky. First camera Eastman was launched in 1888 and came preloaded with film. Once the photos were taken, the camera with films must be sent to the Kodak factory where these films have been translated into photo prints. Though the camera was on track to popularity, the rolls of film were available only in black and white. Thus the photography of this period was devoid of color. Movies were black and white cellulose nitrate is a chemical compound that is similar to cotton dust. A film with a nitrate will deteriorate over time and in the process would release acid gases and oxidizers. The film nitrate was also very flammable. Nitrate films actually laid the groundwork for the first roll film flexible. He also created the basis for the development of 35-mm roll film in the mid-1920s. At the end of 1920, the film support roller came into existence. The film roll was 6cms wide and was covered with a sheet of paper to make it easy for anyone to wear well in daylight. Nine years later, the LRT or twin reflex camera has been developed. Early in the momentum of the 1940s, the market for roll film had won and color films were born. While in 1935, Kodak had already developed their color film called Kodachrome. The new color films used the dye coupled color technology. This technology uses a chemical process, which connected the 3 coats of stain to create a color image. This system is still in use. The next discovery and development is that of a film that was triacetate retardant and flexible. Most photographic films until 1970 were using this technology. The films used came with T-grain emulsions. These silver halides are mainly sensitive to light as a T to pay a fine grain pattern. In an age of digital cameras, it is difficult to imagine what really is the next release of the Pandora’s Box.
