For beginners lighting electronics 3D models, start with a key light to define shape, add a fill light to soften shadows, use a backlight to separate from the background, adjust intensity/color temperature to match the device’s purpose, and add accent lights for details like ports or buttons.
Key light (e.g., Area light above) is your primary source—like a desk lamp on a phone. Fill light (diffused, lower intensity) reduces harsh shadows so features (e.g., keyboard) are visible. Backlight adds depth with a rim. Color temperature: cool (5000K+) for modern tech (gaming consoles), warm (3000K-4000K) for user-friendly gadgets (smart speakers). Accent lights highlight small details without overwhelming the scene.
Practice with Blender’s default Area/Point lights. Start with 3 basics, reference real product photos, and tweak with quick previews instead of overloading lights.
