Airbrush Illustration vs Metalheart
エアブラシ・イラストレーション / メタルハート
Airbrush Illustration comes from Illustration Styles and Metalheart from UI Expression. One is technique and the other style. They are reached for with some of the same intent, which is where they get confused.
Airbrush Illustration
Compressed air lays down gradients with no visible join, and commercial illustration's golden age was built on them, rendering chrome reflections, wet gloss and idealized skin. Before digital, this was what a perfect surface meant.
Metalheart

Early 3D software gave this fin-de-millénaire style its chrome, liquid metal, aggressive bevels and lens flare. Dressed in techno and science-fiction imagery, it ruled rave flyers and games magazines around Y2K.
| Airbrush Illustration | Metalheart | |
|---|---|---|
| Era | 1970s–1980s | 1995–2004 |
| Family | Illustration Styles | UI Expression |
| Kind | Technique | Style |
| Cues | Seamless gradients / Chrome and reflections / Starburst highlights / Idealized smoothness | Liquid-metal chrome / Aggressive bevels / Lens flares / Techno and sci-fi typography |
| Best used for | Product advertising idealizing metal or liquid beyond what a photograph shows · Near-future machines and figures rendered as one seamless surface | Club and rave announcements rebuilt with the texture of that era's 3D · Showing off technology through excess instead of refinement |
| Type | Type kept off the image, a thin sans gathered along the bottom | Extrude the letters, bevel them deep, and bake in mirror reflections |
| Composition | A single subject on a dark plain ground so the reflections carry | One large object at center, the ground filled with grids and beams |
| Material | Layered masking with graded spray and small white highlight points | Chrome, liquid metal, lens flare, reflections carrying surrounding color |
| Caution | Spraying every area with the same even gradient erases the information of form and leaves a soft blur with no edges. | Polishing it clean in current software removes the rawness that came from the crude renderers of the time, and it becomes something else. |
