Q 1. Pick three events in the timeline from this week’s lesson History of Photography: An Introduction, and find photographs of the event on the Internet or in the library and write a paragraph explaining the event in more detail. Include your photographs in the description.
This type of photography was patented by Hamilton Smith in 1856. Thin sheets of dark lacquered iron was used to make a positive image, meaning normal colors and light. It did not need any drying, some the photographer could have the image ready for the costumer in a few minutes. Because this was a non expensive and fast way to make pictures this became a popular method. Often used by photographers in booths, at carnivals or fairs.
Wet plate negatives
The english sculptor Fredrick Scoff Archer invented the wet plate negatives in 1854.
Negatives is reversed, and dark colors appear light and light colors appear dark. By making them on glass plates the image became more trustworthy by keeping more of the details in the image. The glass plate also made it possible to make more than one example of the different images.
He used a collodion emulsion, and with light-sensitive silver salts he coated the glass plate.
There was a disadvantage with this method though. The plate dried fast, so the entire process had to be done quick. This meant that the photographer had to cary around a portable darkroom.
Commercial colour films were brought to the market in the early 1940s. (Except for Kodachrome, which was intruced in 1935). These films used the modern technology of dye-coupled colours – a chemical process connects the three dye layers together to create a full colour image. Despite of the shortcomings, the color photographs improved throughout the 1940s. So a lot of the World war 2 photos were in color.
