History Of Digital Photography

1

What is the history of film photography?

And how does it relate to digital photography today? What was the first method that people used to take pictures, what were the chemicals used, were any of them harmful? How did that lead to digital photography today? How do digital and film photos differ? I would like to understand photography better and if anyone would be so kind as to explain the history and how it has evolved I would greatly appreciate it. Thank you in advance :)

Here you go - a timeline (in fact a couple)

Not really hard to look up yourself really.
