Answer explanation

SARR is way to member it

Circle the image that is using Omni-directional lighting

Answer explanation

Its the one on the right!

I need you to know that I do not believe in you

Select the methods to avoid surface glare and luminous reflections...

• Polarization Filters

• Use different colored light

• Changing the angle of your camera/lighting. 3-D Reflection Geometry

• Alt+f4 the sun

Near IR light can penetrate materials more easily because of the longer wavelength.

• True

• False

Answer explanation

<-------- YOU

Infrared (IR) light interacts with simple material properties, often cancelling color differences

• True

• False

Answer explanation

There is always a way out

Label which camera orientation is for light and dark field lighting geometries.

Answer explanation

A: You are an intelligent being

B: You are smarter than an ape

Consider the following statement:

¬A ∧ ¬B

Key Concept 2: The "_" defines the boundary between light and dark fields

Answer explanation

Slide said key concept so you should prolly learn this

Key Concept 1: Name the two different lighting geometries that alter whether flat surfaces appear light or dark

• High/Low Fields

• Bright/Dark Fields

• Light/Dark Fields

• Contrast/Flat Fields

• Signal/Noise Fields
