How a Digital Camera works
How a film camera works

Its amazing how digital Photography has expanded into everyday use. Cost, environmental considerations (no chemicals) and portability of images to the Internet and beyond have made this media a winner. 

With this in mind digital and film cameras have a lot in common and not much that you may have learned from experience with film photography cannot be applied to digital. But the opportunities for professional growth are infinite with digital

Digital Camera anatomy

Camera means "a room" (latin) and the first cameras where in fact small rooms with a small pinhole that allowed light to shine on a screen.
An artist would sit in and draw the image of the view outside the camera obscura as it was cast onto the screen upside down (inverted)

Later it was found that lenses could resolve the image with greater resolution and clarity.
Next it was found that certain light sensitive chemicals could used to coat films and the hand drawn images became a thing of the past as glass lenses focused crisp images onto film .

Pressures to adapt to new media in the 90's such as the Internet and digital printing lead to the development of the digital light sensor that replaced film and the rest is history.

The short focal length required in digital cameras allows for really compact cameras and the constant miniaturization of electronics has paved the way for incredible image storage abilities (often over a thousand images on storage media make for great costs and portability).
