Photoreal, 3D cartoon, storybook illustration, live-action pastiche. Each is a register, and the choice is strategic rather than decorative: it decides what the audience will forgive and what they will notice.
Registers are also the antidote to volume fatigue. A house style makes the second piece cheap and the fifth invisible. Fixing a list of registers before any frame exists is how a run of seven pieces stays recognisable as one brand without ever looking like the same advert twice.
QUESTIONS PEOPLE ASK
How do you stop social content looking repetitive?
Decide the registers before production, not during it, and give each its own plate set and prompt vocabulary. Let the brand mark carry the continuity instead of the style.
