Photography involves using light or radiation to record images on a light-sensitive medium. This process has been used since 1826 with the camera obscura, a darkened chamber that projects an image. A digital single-lens reflex (DSLR) camera allows the photographer to view through the lens to see exactly what will be captured using a mirror and prism system. DSLR cameras today come in various sensor formats like full frame, APS, and medium format. Large format cameras include view and field cameras with very large sensor sizes. DSLRs have advantages over point-and-shoot and rangefinder cameras like better image quality and more manual control options, though they can be larger and heavier. Proper camera care includes

1. Intro To The Digital SLR

2. Photography
 “Photography” is derived from the
Greek words photos (“light”) and
graphein (“to draw”)
 It is a method of recording images by
the action of light, or related radiation,
on a light sensitive medium
 This process has been with us since
1826

3. Camera Obscura
Latin; camera for “valued chamber/room”,

4. 35mm SLR & DSLR Camera:
Basic Components

5. Digital SLR Cameras Today
 Most Importantly, they are a sealed/or vaulted chamber just like a camera
obscura...why?
Why DSLR?
 A digital (D) single-lens reflex (SLR) camera is a camera that uses a mirror
and prism system that permits the photographer to view through the lens
and hence see exactly what will be captured
Digital Sensor Formats
