Fixing the shadows

Camera Obscura

The Camera Obscura was originally created around 200 years ago. However, it’s not the world’s first camera as before them was pinhole cameras neither need a power source. They project in real time the landscape Infront of the camera onto the back walls of the room or box. This was how art first started becoming more detailed after the medieval period as painters would use the camera obscura method and paint it onto the walls and on canvases. In 1826 Joseph Niepce was the first known person to create the first photograph of a scene in Italy by using chemicals which change colours in the light to capture the scene projected.

Calotypes –  Henry Fox Talbot

Invented in 1841 next was “The Art Of Photogenic Drawing” where William Henry Fox used salt and silver nitrate to create what we now know as a Calotype. He used pressed plants on a sheet of chemicals and covered them in a glass sheet to print out the shape in the sun.

My Cyanotype

I made this piece in class by using leaves from outside collected on the school grounds. I then positioned them on the paper this way so it was clear what each one was and they weren’t over-lapping. I then left them outside in the sun with a glass sheet on-top till the paper had turned a noticeably different colour and left shadows of the plants I had placed there.

Louis Daguerre – Daguerreotype

The process of the Daguerreotype created in 1837 made it possible to turn the image inside of the Camera Obscura and preserve it. The Daguerreotype is made with a sheet of copper with a thin piece of silver which is polished until mirror like, then it’s a sensitised in a lighttight box with iodine and bromine vapours until it turns a yellow colour. This produces silver iodide. The sheet is then inserted into the camera without any light touching it. After that its fixed in a sodium and then intensified with gold chloride and washed in water. The images mirror the reality of the pose due to the Daguerreotype process.

Richard Maddox

In 1851 Frederrick Scott Archer invented the Collodion process. This was revolutionary in the evolution of photography as it took only 2-3 seconds of light to create an image compared to the 1 to 5 minutes it took previously. However, Richard Maddox realised his health had been affected due to the ether vapours from this process and began his search for a replacement. He produced the idea in 1871 of coating cadmium bromide and silver nitrate in gelatine on a glass plate. This made it possible for cameras to be small enough to be hand-held.

George Eastman

Eastman tried for 3 years to create a formula and by 1880 invented the correct formula. He also invented a machine capable of creating these plates at a fast rate which made it possible for him to manufacture and sell to other photographers which is when he started his company in London due to the high rates of businesses in the area henry Strong was very impressed, so he invested some money into it. In 1892 the company as renamed the Eastman Kodak company as photography developed further.

After Eastman realised that the plates were making the photographers hands “go bad” he started the trade with the idea of film in rolls the venture was immediately successful but the paper grain was prone to showing up through the picture. This sparked Eastmans new idea to coat the paper in soluble gelatine and the insoluble light sensitive gelatine. With the Kodak camera in 1888 photography was ready available to pretty much everyone

In 1957 the first digital image was created in the USA using the first operational stored program known as the SEAC.

The 1960s space race also drove photographers to think of a new way to take photos as film would be impractical  to take to space. NASA used a magnetic tape recorder to send the tv camera into electrical impulses to send back to earth and they had the first photo of mars. Later Sasson took one of the later models of a movie camera and connected it to the most recent CCD electronic sensor and created a prototype. The company Sony then created a version small enough to hold and sell in a shop the Sony Mavica the first known digital camera.
