The Basics . . .

The day before we ran of to do our pinhole cameras we spent some time finding out what Photography and Cameras are all about. We learnt the definition of

-Photography-

*Photography is the process, activity and art of creating still or moving pictures . . . light patterns reflected or emitted from objects activate a sensitive chemical or electronic sensor during a timed exposure*

We also learnt various other things like, genres of photography (which include aerial, black and white, portrait, still life, stock,underwater, commercial and many others) what camera means. . .

* A device that records images, either as a still photograph or as a moving image known as videos or films.*

-Exposure-

*the period of time in which the photographic medium is exposed to the light from the scene, equivalent exposures can be made with a  larger aperture and a faster shutter speed or a corresponding smaller aperture with the shutter speed slowed down*

Aperture was an important part of what we needed to know to make our pinhole cameras.

*Aperture is a hole or opening through which light travels, this is measured in f-stops*

-Lens-

*The lenses of a camera capture the light form the scene and bring it into focus for the photographic medium*

-Shutter speeds-

B – bulb

1 – 1 second

2 – ½ second

4 – 4^th second

8 – 8^th second

15 – 15^th second

30 – 30^th second

60 – 60^th second

125 – 125^th second

250 – 250^th second

500 – 500^th second

1000 – 1000^th second

(smaller the number the bigger the aperture)
