Calotype or talbotype is an early photographic process introduced in 1841 by William Henry Fox Talbot, using paper coated with silver iodide. The term calotype comes from the Greek καλός (kalos), "beautiful", and τύπος (tupos), "impression".
Talbot made his first successful camera photographs in 1835 using paper sensitised with silver chloride, which darkened in proportion to its exposure to light. This early "photogenic drawing" process was a printing-out process, i.e., the paper had to be exposed in the camera until the image was fully visible. A very long exposure—typically an hour or more—was required to produce an acceptable negative.
In late 1840, Talbot worked out a very different developing-out process (a concept pioneered by the daguerreotype process introduced in 1839), in which only an extremely faint or completely invisible latent image had to be produced in the camera, which could be done in a minute or two if the subject was in bright sunlight. The paper, shielded from further exposure to daylight, was then removed from the camera and the latent image was chemically developed into a fully visible image. This major improvement was introduced to the public as the calotype or talbotype process in 1841.
We are the talk of the town
No need for negligence
We move so slow as the surface surfaces into focus
We're reflecting onto your face
Into your face into focus
We're reflecting into your face
Onto my lense into focus
You come out pale you say you want it that way
Don't close your eyes or we have to take it again
We've been waiting for this moment for so long
You smile so beautiful
We wait for the red light to go off
We've been waiting for this moment for so very long
We wait for the red light to go off
We know that this is it
You walk in white
I stand in black
Wait for me to set the setting the
Flash will surely blind you must close your eyes
The shutter closes for a second
cutting off the ties that could have stopped us
Another clicking sound you want to see how you came out
We've been waiting for this moment for so very long
We wait for the red light to go off
We know that this is it
You walk in white
