“ You’ve got to push yourself harder. You’ve got to start looking for pictures nobody else could take. You’ve got to take the tools you have and probe deeper. – William Albert Allard

Basic Photographic Principles1. Focus attention on the main subject
– Rule of thirds (tic tac toe)
– Placement of subject (Empire State Building – center of attention)
– Framing (we are conditioned to looking through a frame)
2. Simplify subject through focus
– Clutter in background
– Focus on the subject (eyes)
– Depth of field (aperture lowest number)

Basic Photographic Principles3. Emphasis on Motion
Blurred, froze or panning More interesting and alive Shutter speed Panning (1/15 – 1/30) Blurring subject or blurring background Freezing an expression (jumping in a pool)
Basic Photographic Principles4. Selective lighting
– Subject should be the most lit portion of the photo
– Can be done in post processing– Vignetting– Filters and lens baby
Basic Photographic Principles5. Color
– Saturated vs unsaturated– Over saturation– Under saturate to emphasize subject
Recap
• Emphasize your subject by placing them off center• Make your subject larger• Think about how your framing your subject• Use of lighting• Making sure the subject is in focus• Use motion pg.15• Use of color
The Window: Imagine1. Aperture is the size of the window. If it’s bigger more light gets through and the room is brighter.
2. Shutter Speed is the amount of time that the shutters of the window are open. The longer you leave them open the more comes in.
3. Now imagine that you’re inside the room and are wearing sunglasses. Your eyes become desensitized to the light that comes in (it’s like a low ISO).
The Big Three

Aperture (f-stops)
Aperture refers to the size of the opening inside the lens that the light must go through to reach the film. Aperture is measured in f/stops as indicated in the series below:
1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45
Depth of Field
• Used to describe the region in front and behind the focus point that appears sharp in the final photograph.
• It is controlled by lens length, subject distance, and aperture setting.
Depth of Field Preview
A 'depth of field preview' button is one that closes down the aperture without engaging
the mirror or shutter.
Using the DOF button, you can see what will be sharp in the final photograph.
Shutter SpeedsThe shutter-speed selector controls the length of time that the shutter remains open.
Understand that each progression represents half as much light as the preceding number. Common shutter settings are as follows:
1 second, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, and 1/2000 second.
Shutter Speed and Sharpness
When hand holding your camera, be sure that your shutter speed is fast enough to produce
a sharp photo.
1/60
Film Speed
Film Speed Rating - ISO All film has a speed rating, whether digital or traditional. The ISO rating describes how quickly the film reacts to light.
– Film speed uses stops, just like shutter and apertureFor example, going from ISO50 to ISO200 buys you 2 stops more light.
Trade Offs in Exposure Settings
• Large and small apertures (small f/ratio numbers) are subject to lens unsharpness.
• Aperture determines the depth of focus. • Long exposure times require a tripod, and will usually
blur the photo if you photograph moving subjects. • Low film sensitivities (low ISO number) require longer
exposures.
Mode DialBasic Zone (Pre-Sets)• Portrait Mode• Landscape Mode• Night Scene (portrait) Mode• Black and White Mode• Macro (close up ) Mode• Sports Mode
Creative Zone• P - Program
• TV - Shutter priority
• AV - Aperture priority
• M - Manual
Mode DialBasic Zone (Pre-Sets)• Portrait Mode Use this mode when you
want a subject in the foreground in sharp focus.
• Landscape Mode Use this mode when you want a wide-angle shot with the background in focus.
• Night Scene (portrait) Mode Use this mode when you're shooting a subject at night. Illuminates the subject with the flash, while keeping the shutter open longer to provide more light for the background. Creates a balance.
• Black and White Mode Use this mode to take pictures in black and white
• Macro (close up ) Mode Use this mode for extreme close-ups. Blurs the background, narrow DPF.
• Sports Mode For shooting scenes with lots of motion, which you want to capture without blurring.
Mode DialCreative Zone
• P - Program - Program mode is much like Automatic mode - the camera will still do most of the setup work for you -- but it allows you to manually override some settings
• TV - Shutter priority - used for manual shutter speed • AV - Aperture priority - used for manual aperture• M - Manual - used for fully manual control
This allows you to manually adjust both shutter speed and aperture for the same shot, as well as focus.
