Portraits & Caricatures Technology & Digital Applications 5

Question 1

What does the term 'rasterization' mean when transitioning from a vector caricature to a final digital image?

Accepted Answer

Converting mathematical vector paths into a pixel-based (raster) image at a specific resolution

Answer

Rasterization converts resolution-independent vector data into a fixed grid of pixels at the chosen output resolution.

Question 2

In digital portraiture, what is the purpose of a 'color profile' such as sRGB or Adobe RGB?

Accepted Answer

To define the range of colors the file can represent and ensure consistent color across devices

Answer

Color profiles standardize how color values are interpreted, so a red painted on screen looks the same red when viewed on another monitor or printed.

Question 3

Which digital tool mimics the physical act of blending two adjacent colors on a canvas by averaging the pixels between them?

Accepted Answer

Smudge / blend tool

Answer

The smudge or blend tool drags and mixes pixel color values, simulating how a finger or tortillon blends traditional media.

Question 4

What advantage does working at a high canvas resolution (e.g., 4000×5000 pixels) offer a digital caricature artist?

Accepted Answer

Ability to print at large sizes or zoom in without visible pixelation

Answer

A high pixel count preserves fine detail when the artwork is enlarged for print, poster, or merchandise use without quality loss.

Question 5

When livestreaming a caricature drawing session, which software feature reduces the file/stream size while maintaining smooth playback for viewers?

Accepted Answer

Video codec compression (e.g., H.264/H.265)

Answer

Modern video codecs like H.264 use temporal and spatial compression to dramatically reduce bitrate while keeping motion smooth and detail visible.
