Challenge 3: An Expensive Webcam Looking Worse Than a Cheaper One — Solution Walkthrough

A likely explanation before blaming the camera:

Per this chapter's own material, lighting has a genuinely bigger
practical impact on perceived webcam quality than the camera hardware
itself — a cheap webcam in good lighting often looks noticeably better
than an expensive webcam in poor lighting. Before assuming the
expensive webcam itself is somehow underperforming, checking the
actual lighting conditions in each person's own setup is a more likely
place to find the real explanation.

Why this is a reasonable first suspicion rather than the camera:

If the friend's cheaper webcam is positioned in a well-lit room or
setup, and the creator's expensive webcam is in dim or uneven
lighting, the lighting difference alone could easily produce the
observed quality gap — regardless of which camera is technically more
capable on paper. Camera hardware determines the theoretical resolution
and sensor quality, but poor lighting can make even a technically
superior camera's output look grainy and unclear, since a sensor
receiving little light generally has to compensate in ways that
degrade image quality.

What to check before considering a hardware upgrade:

Improving lighting in the creator's own recording setup, and
comparing results again, before spending money on a different camera
that may not actually solve the real underlying problem.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise applies this chapter's own lighting-vs-hardware point to
a realistic, slightly counterintuitive scenario, correctly suggesting
lighting as the more likely explanation rather than assuming the more
expensive hardware must somehow be the one underperforming.
