Eye Features Camera Features
Auto White Balance – doesn’t see shadows as Auto white balance included but not accurate –
blue or fluorescent lights as green confused by direction (where) of light and
mixed lighting sources. Can’t identify primary
light source without help.
Auto Exposure – wide contrast range covering Auto exposure included but confused by high
highlights and shadows with quick adjustment. contrast. Doesn’t know its own limitations.
Makes choices based on brightest areas.
Auto Focus – face recognition built in. Multiple Face recognition easily confused. Camera
focus points built in. (Your choice) operator must direct focus to the correct
subject. Limited focus distance.

5. Success Formula: Learn To Love Manual Control
(Who’s More Capable, You Or Your Camera?)
• When an all-auto camera reacts to changes in light levels, light
sources, wide audio swings, everything it does is obvious and
distracting.

7. Focus Attention – Get Audiences To Pay
Attention To What You Want Them To See
Achieved By:
• Lighting – foreground & background separation – create contrast – makes
image appear sharper.
• Think principal subject – brighter than other pictorial elements.
• Create dimensionality by using light and shadow. Shadow defines depth.

Attention To What You Want Them To See
• Technique: Start with 3-point lighting consisting of key (main), fill (fills in
detail & lightens shadow), back or separation light.

10. Everything You Wanted To Know About Light
Lighting Characteristics
• Color
• Hard or Soft
• Sun is a hard light, a direct light - well defined shadows
• Bounced lights are soft - less shadows and good wrap
• The bigger the light source, the softer the light
• Distance & Light
1. If you move light close to your subject light will fall off very rapidly; further away will fall
off more slowly. When you pull back you can actually light more space.
2. Inverse Square Law - means of calculating fall off

34. Exposure
What Does It Mean To You?
Why is It Important to You?
Answer:
The amount of light required for the camera’s sensor
to capture the widest range of bright highlights and
dark areas without over or under exposing the image.
34
35. Exposure
How Your Camera Interprets A Scene
Why Understand Gray Scale or Zone?
• Your video camera is color blind.
• Exposure is set in relation to Middle Gray
(Zone V) – 18% reflectance.
• Zones are a method of quantifying shades.
• Determining how a color corresponds to a
shade of gray produces more consistent
results.

By The Numbers (Advanced)
• ISO – Chip sensitivity to light frequently called “speed”
• F-stops refer to the size of the lens opening called “aperture”
• Shutter Speed – how fast the shutter letting in the light opens
and closes exposing the chip
• Video cameras do not have a mechanical shutter. When
referring to speed, we mean how fast the video camera
samples information from a chip. If you select 60th of a second
- (standard) shutter speed - this means sampling all the
information in a 60th of a second. Source: www.videojug.com

Ear Features Microphone Features
Wide dynamic range from a whisper to Limited to microphone specifications

Seamless level adjustment. Requires monitoring to avoid distortion
on the high (loud) end and noise on
the low (quiet) end.
Directional sound awareness. Depends on each microphone’s
acceptance pattern. Each microphone’s
coverage area varies.
57
58. Audio Mastery
Microphones – Two Basic Types
Omni Directional: pickup sound from every direction equally
Better at resisting wind noise or mechanical handling
Less susceptible to popping “p,” “b” or “t”
Directional Microphones: Sounds best from the front. Tends to reject sound
that comes from other directions
• Directional Types: cardioid, subcardioid, hypercardioid, bi-directional
58
59. Audio Mastery
Collecting Sound Objectives
• Suppress unwanted noise
• Reduce effects of reverberation
• Increase gain before distortion – crank up the good sound

60. Audio Mastery
Visualizing Microphone Pickup Patterns
Patterns, called polar patterns, should be taken as the floor plan of a microphone’s
response; where the microphone hears the best.

Sound Recording – Best Practices
• Recording level should be as close to zero on your meter as possible without
increasing background noises.
• Get microphone or camera as close to subject as possible.
• Metering: Level should be as close to zero as possible with increased background
noise.
• When setting level have subject speak normally. The subject should not move
backwards or forwards during the test.
• Don’t use AGC (auto gain control).
• Record at least a minute of ambient sound (called room tone) with no one talking.

A Moving Camera
• Use a camera stabilization system – it
separates your gait from the camera.

Additional Benefits: A moving camera creates motion
where there is none. Enables multiple angles and diverse
shot compositions (wide angle to close up) without editing.
Allows crossing the line (the 180 degree rule).

Light Controls and Shaping
• Diffusion in front of lighting instrument: softens light and limits intensity.
Changes character of light. Suggestions: Rosco Opal Tough Spun 3010,
Tough Silk 3011, Tough ½ White Diffusion (also called Lee 216).
• A single lighting instrument with two intensities: Use ½ scrim at one or 2
stop control.
• Lessening light intensity on reflective surfaces: nets with one or two stop
control.
• Removing light from where you don't want it to be: flags or black show
cards in frames.

The Essentials
Microphone Level - audio that comes directly from a microphone.
• Diagnosis: can barely hear it.
Line Level – amplified audio that comes from a mixer, audio system.
• Diagnosis: distorted audio or pinned needle.
Phantom Power –
• Provides power to use the microphone at the camera input or from a mixer.
• Unlike Dynamic, Condenser microphones require a power source. If you don't power
from an external source must boost in line. Will require some kind of battery.
Balanced/Unbalanced Audio Connectors –
• Balanced audio connectors are less prone to RF(Radio Frequency), hum and buzz.
• Unbalanced audio connectors can be ¼ inch or 3.5 mm and are more prone to RF, hum
and buzz.

80. Video Promotion for Small Businesses, Artists,
Consultants
• When showing your product, animate it.
• With a location, walk in and around as if you were a viewer.
• With paintings and photographs, move camera across the painting or photo –
think Ken Burns.
• Use lighting to create dimensionality for sculpture or installations.
• Create a mood using music, sound effects. For example: bells, foot steps, thunder.
• Create a back story and cut back and forth between you talking directly to the
camera and your work.
• What can you say about your product or service? If you can show it with footage
and stills, do it.
• You can talk about process, materials, specialized tools, why you applied the paint
the way you did.
• You can talk about influences, inspiration, why you are passionate about what you
do.
