Stephen J Sasson, born July 4th 1950 in Brooklyn New York, in as
American engineer and the inventor or digital camera.
His invention began in 1975 working for Eastman Kodak Company
The digital camera was patented in 1978 but received widespread
interest in 2001 when Steve Sasson received the Eastman Innovation
Award from Kodak and a local newspaper wrote about the camera.
It used a solid-state CCD image sensor (as opposed to CMOS censor). It
weighted 8 pounds, recorded black and white images to a cassette tape,
had a resolution of 0.01 megapixels (as opposed to 21 mpix today), and
took 23 seconds to capture its first image in December 1975.
The first commercially available digital camera was in 1990 Dycam
Model 1.
On November 17th, 2009, President Barak Obama awarded Sasson the
National Medal of Technology and Innovation. This is the highest honor
awarded by the US government to scientists, engineers and inventors.
In 2011 he was inducted into the inventors Hall of Fame.

The primary advantage of consumer level digital cameras versus film
cameras is that digital camera eliminates the need to purchase a film
and hence a huge saving as well as to take the same picture over and
over to the photographer’s satisfaction.
Next important advantage is the ability to look at the display at the back
of the camera to see if the exposure is right (including the histogram).
Next important step in image processing is tethering, which is basically
the ability to connect a digital camera to a computer, a specialized video
monitor, a tablet and even a cellphone.
Tethering can be achieved through a wire, using a USB or fire wire cable,
or a wireless device (802.11 specification), Bluetooth and a cellular
network.
This gives tremendous opportunity to photographers to see the picture
taken live on a calibrated monitor, or even to send the picture remotely
to his office for fast processing and release and use.
Finally, an important step forward is the ability to store the images on
hard drives and DVD. Card reader is of a great assistance in the matter.

That was briefly the evolution of photo processing, and thank you very
much for your attention.
