Fox Talbot and camera in 1864 portrait (on the PetaPixel<\/a> website).<\/p><\/div>\n

Toronto<\/strong>. The title is a riff on the old saying, “… build a better mousetrap …<\/a>“. One of the earliest cameras was called a mousetrap by the spouse of its creator. It was basically a very small camera obscura. A light tight wooden box held a piece of salted paper<\/a> at one end and a short focal length lens at the other.<\/p>\n

Next to the lens was a small corked hole. The cork was removed briefly to check the progress of the exposure (a latent image was not used – the salted paper was like the printing out paper of a later age).<\/p>\n

The resulting exposure was inverted – light areas were dark and vice versa<\/a>.We would later recognize this as a negative. By placing a second sheet of salted paper under the ‘negative’ and exposing the sandwich to sunshine, a ‘positive’ print was created.<\/p>\n

All this was part of William Henry Fox Talbot<\/a>‘s experiments shortly before Daguerre’s iconic announcement. Talbot had succeeded in ‘fixing’ the ‘negative’ and ‘positive’ salted \u00a0papers by using a diluted solution of salt.<\/p>\n

We have come a long way since the late 1830s in film based photography: more sensitivity, better resolution, latent images, greater flexibility – and better cameras!<\/p>\n
