Key visual
The main graphic idea a campaign or brand moment is built around, designed to survive across ads, pages, packaging, and motion.

What it is
A key visual is the hero graphic concept that anchors a brand moment or campaign, then supplies the parts and rules for every adaptation. TBWA\Chiat\Day's 2003 iPod silhouette campaign had a clear one: dark dancing figures, white earbuds and cables, and flat fields of saturated color. Individual ads changed, but the visual proposition stayed intact.
Reach for one before producing a campaign family across billboards, social posts, landing pages, retail, and motion. The master should establish the subject, composition, graphic device, color behavior, and a safe place for copy, then prove that those choices survive more than one aspect ratio.
Gotcha: a beautiful hero image is not automatically a key visual. If the idea depends on one exact crop or leaves no room for headlines, it cannot carry a system. Test the concept in wide, square, and vertical formats before commissioning a full set of assets.

Create a key visual for [CAMPAIGN] built around [SUBJECT] and [ONE GRAPHIC DEVICE]. Assemble the master in Adobe Photoshop with the subject, background, device, and copy zones as separate Smart Objects. Use [BRAND COLORS], reserve a quiet area for a 6-word headline and CTA, and define one crop rule that keeps the subject recognizable. Adapt the same concept to 16:9, 1:1, 4:5, and 9:16 canvases without adding new motifs. Present all four beside the master and list the elements that must never change.
