Strobe/flash is a high-impact accent that must be used sparingly because of photosensitivity risk, never as a default

A strobe-flash — rapid on/off or bright/dark alternation — is the highest-impact visual accent available, which is exactly why it must be reserved and never run as a continuous default. Sustained strobing carries a real photosensitivity (seizure) risk for audiences, so it is a safety constraint, not just a taste one. Treat it like an impact hit in music: deploy it on an accent or a phrase boundary, then return to a calmer state. A set that strobes throughout both desensitizes the accent and endangers viewers.

Examples

Fire a one-frame full-frame flash on the drop, then cut back to steady motion — high impact, used once. Contrast: strobe-flash looping every frame for a whole section, which reads as an assault and risks harm.

Assessment

Explain why strobing should be reserved for accents rather than used as a base texture, naming both the craft reason and the safety reason. Where in a 16-bar phrase would you place a strobe accent?
