Camera Obscura

From Wikipedia,

• They say “The camera obscura is an optical device that projects an image of its surroundings on a screen. It is used in drawing and for entertainment, and was one of the inventions that led to photography and the camera.”

Motion Blur

If shutter speed is fast Freeze action

The size of opening.

Roles of Aperture•Larger opening lets more light through

per second than a smaller one.

•The size of opening also affects the depth of field in the photograph.•Large opening

For next class,• Have two rolls of 35mm black and white film exposed with

18 cuts with Av mode, 18 cuts with Tv mode, 18 cuts with Manual mode, and 18 cuts with Dep mode. Choose Kodak tri-x or Ilford HP5plus.

• Also, bring Negative sleeves and photographic paper- 5 across seven down they come in packs of 25 or 100 photographic paper
