camera photography history
I need major help on my history of photography project… i’m totally stuck :’(?
So many websites are telling me different things. so can someone please help me out; im in a right muddle.
Right:
What is the difference between the camera obscura and a pinhole? i know a pinhole is smaller but i have to write about the invention of the pinhole camera and i dont wanna repeat my ‘camera obscura’ section.
I also have to do a section on history of fixing images.
I’ve got the Niepce created the first fixed image (though i dunno how he worked out how to fix it)
then after that i have to write about the first permanent negative image. That was talbot wasn’t it? and whats the difference between that and Niepce?!
Then i have to write about Daguerrotypes and Calotypes.
a) shouldnt daguerrotypes be mentioned with Niepce?
b) Whats the difference between the two!?
I’m almost in tears. will someone please help me?
1) same principle:
http://en.wikipedia.org/wiki/Pinhole_camera
http://en.wikipedia.org/wiki/Camera_obscura
It only seems that the pinhole actually uses film, while the other one was mainly for drawing.
2) http://en.wikipedia.org/wiki/Niepce
“He placed the sheet inside a camera obscura to capture the picture, and eight hours later removed it and washed it with lavender oil to remove the unexposed bitumen.”
3)http://en.wikipedia.org/wiki/Photography
“By 1840, Talbot had invented the calotype process, which creates negative images. John Herschel made many contributions to the new methods. He invented the cyanotype process, now familiar as the “blueprint”. He was the first to use the terms “photography”, “negative” and “positive”. He discovered sodium thiosulphate solution to be a solvent of silver halides in 1819, and informed Talbot and Daguerre of his discovery in 1839 that it could be used to “fix” pictures and make them permanent. He made the first glass negative in late 1839.”
4) a) yes: http://en.wikipedia.org/wiki/Photography
“The first permanent photograph was an image produced in 1825 by the French inventor Nicéphore Niépce. However, because his photographs took so long to expose, he sought to find a new process. Working in conjunction with Louis Daguerre, they experimented with silver compounds based on a Johann Heinrich Schultz discovery in 1724 that a silver and chalk mixture darkens when exposed to light. Niépce died in 1833, but Daguerre continued the work, eventually culminating with the development of the daguerreotype in 1837″
