A little history
An engineer by the name of Steve Sasson was the one to invent the first digital camera in December 1975. Steve Sasson was an engineer that worked at Eastman Kodak. He made a blog post to social media in the year 2007 talking about how he had came to making the digital camera.
"It had a lens that we took from a used parts bin from the Super 8 movie camera production line downstairs from our little lab on the second floor in Bldg 4. On the side of our portable contraption, we shoehorned in a portable digital cassette instrumentation recorder. Add to that 16 nickel cadmium batteries, a highly temperamental new type of CCD imaging area array, an a/d converter implementation stolen from a digital voltmeter application, several dozen digital and analog circuits all wired together on approximately half a dozen circuit boards, and you have our interpretation of what a portable all electronic still camera might look like." -Steve Sasson > Eastman Kodak
What Elements make a Digital Camera
where does Cadmium, Aluminum,Nickel, and Lanthanum come from??
The element Cadmium is produced in multiple countries. China, Japan, and Korea are the world's largest producers, followed by Mexico, the United States, the Netherlands, India, the United Kingdom, Peru and Germany.
The element Aluminum is naturally found in the form of bauxite (a rock that contains aluminum oxides an dioxides), an aluminum ore contains oxide, or alumina. We surface mine bauxite from places in Australia, Brazil, Suriname, Jamaica and other parts of the world.
The element Nickel is mined from multiple nickel ores such as= pentlandite and pyrrhotite (iron Nickel sulfides, the two most important nickel ores), garnierite (hydrous Nickel silicate), millerite (Nickel sulfide), and niccolite (Nickel arsenide).
The element Lanthanum is mostly obtained from lanthanum-rich monazite and bastnasite. Other lanthanum-bearing minerals include allanite and cerite. It is mined in the USA, China, Russia, Australia, and India
