<span>I doubt if anyone knows the exact exposure time for any particular daguerreotype image. That being said, the typical exposure time was a variable between 15 to 40 seconds. This is because the plate was sanitized by iodine fumes. The time of the fuming was a variable. Depending of the quality of the camera lens and the brightness of the day let make a guess – the exposure was likely at about 30 seconds. 

The first permanent photograph was taken in 1827. The process was the invention of Nicephore Niepce and is titled A View From The Window at Le Gras. This picture was taken in France and it is now at the University of Texas at Austin. The exposure was 8 hours long. Leuis Jacques Mande Daguerre using an improved process took two pictures of the street titled Two Views of the Boulevard du Temple, Paris. Now at the Bayerisches National Museum, Munich.</span>
