(Camera Obscura)
2. Aperture (Depth of field)
3. Shutter
4. ISO
5. Shooting Mode
“Exercise”
• - Shooting proper exposure pictures with Av, Tv, M mode… etc
• - A quiz about Aperture and Shutter speed values
• - Film developing demo
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.”
the light goes straight on
Camera is..
“Photography is a painting with the light”
Proper Exposure
•What is the exposure in photography?
•What is the proper exposure in photography?
Which one is the proper exposure?
ISO- The level of sensitivity of your film to
available light.
•“Lighting gathering” ability
Lower ISO
Higher ISO
Require more light to get a good
exposure
Less light to get the right exposure
BUT, You will get noise
Shutter speed-
The length of time a camera’s shutter is open
when taking a photograph
1/1000 1/250 1/4
Motion Blur
If shutter speed is fast Freeze action
completely If shutter speed is
slow‘motion blur’
ApertureThe lens diagram

lens.
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
shallow depth of field•Small
opening
Deep depth of field
Let’s think about bathtub
Depth of field-Three dimensional field of
your image

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
