Resolution Requirements
Minimum: 1500 × 2100 pixels (300 DPI at print size). Most modern smartphones exceed this.
Lighting Tips
Natural light is best. Shoot outdoors in open shade. Golden hour gives warm, flattering light. Position subject's face towards the light source.
Action vs. Posed Shots
Action: Use burst mode, 1/500s shutter minimum. Posed: Slight angle to camera, hold equipment naturally.
Background Tips
Simple, uncluttered backgrounds work best. CardStar's AI can remove busy backgrounds automatically.
Common Mistakes
Avoid: blurry photos, harsh shadows, cropping too tight, low resolution from screenshots.
