Question 1

What kind of light does a table lamp give off?

Accepted Answer

Incandescent

Answer

Traditional table lamps typically use incandescent light bulbs, which produce light by heating a metal filament until it glows. While LED and fluorescent options are now common, 'incandescent' refers to the classic bulb type that generates light through heat, characteristic of many household lamps. Mercury vapor lamps are used for streetlights or industrial settings, and sunlight is natural light.

Question 2

What does a reflector do?

Accepted Answer

Redirecting light

Answer

In photography and lighting, a reflector is a surface used to bounce or redirect existing light onto a subject. It doesn't generate light itself but rather manipulates the direction and intensity of light from another source. This helps to fill shadows, soften harsh light, or create specific lighting effects, making it a crucial tool for light control.

Question 3

The three separate lines in an RCA cable are each marked by a different color. Are they?

Accepted Answer

Yellow = video, White = left channel, Red = right channel

Answer

Standard RCA composite video and stereo audio cables use a specific color coding to ensure correct connections. The yellow connector is designated for composite video signals, while the white connector carries the left audio channel. The red connector is used for the right audio channel, allowing for proper stereo sound reproduction.

Question 4

When you use an external flash to shoot a wedding, you should use ISO?

Accepted Answer

200

Answer

When using an external flash, especially in a controlled environment like a wedding, a lower ISO setting like 200 is generally preferred. This allows for cleaner images with less digital noise, as the flash provides ample light, reducing the need for the camera sensor to be highly sensitive. While ISO 100 offers even lower noise, ISO 200 often provides a good balance between image quality and slight ambient light capture or faster flash recycling times.

Question 5

What is the equivalent of 1000 petabytes?

Accepted Answer

1mb

Answer

In standard data storage units, 1000 petabytes (PB) is equivalent to 1 exabyte (EB), as one exabyte comprises 1000 petabytes. A megabyte (MB) is a significantly smaller unit, representing 1/1,000,000th of a terabyte or 1/1,000,000,000th of an exabyte. Therefore, the provided answer of 1mb is incorrect based on standard computing definitions and unit conversions.
