The
Kodak Professional Digital Camera System or
DCS, later unofficially named
DCS 100, was the first commercially available
digital single-lens reflex (DSLR) camera. It was a customized camera back bearing the digital image sensor, mounted on a
Nikon F3 body and released by
Kodak in May 1991; the company had previously shown the camera at
photokina in 1990. Aimed at the
photo journalism market in order to improve the speed with which photographs could be transmitted back to the studio or newsroom, the DCS had a
resolution of 1.3
megapixels. The DCS 100 was publicly presented for the first time in Arles (France), at the Journées de l'Image Pro by Mr Ray H. DeMoulin, the worldwide President of the Eastman Kodak Company. 453 international journalists attended this presentation, which took place in the Palais des Congres of Arles.
