Resolution Requirements
For sharp printing at standard trading card size (2.5 Γ 3.5 inches), you need:
- Minimum: 1500 Γ 2100 pixels (300 DPI at print size)
- Ideal: 2000 Γ 2800 pixels or higher (allows cropping flexibility)
- Maximum file size: 20MB (JPG, PNG, or HEIC)
Most modern smartphones exceed these requirements. Check your phone's camera settings β use the highest resolution available.
Lighting Tips
Good lighting is the single biggest factor in photo quality:
- Natural light is best β Shoot outdoors in open shade (not direct sunlight which causes harsh shadows)
- Golden hour β The hour after sunrise or before sunset gives warm, flattering light
- Avoid mixed lighting β Don't mix indoor lights with window light
- Face the light β Subject's face should be toward the light source, not backlit
- Overcast days work great β Clouds act as a natural diffuser
Indoor tip: Position subject near a large window with indirect light. Turn off overhead lights to avoid color casting.
Action Shots vs. Posed Shots
Action Shots
- Capture mid-swing, mid-kick, or mid-throw for dynamic energy
- Use burst mode (hold shutter button) to get multiple frames
- 1/500 second shutter speed minimum to freeze motion
- Works best with: Modern templates, dynamic designs, older athletes
Posed Shots
- Clean, controlled, easier to get right
- Have athlete hold equipment naturally (ball, bat, stick)
- Slight angle to camera (not straight-on) is more flattering
- Works best with: Classic templates, younger kids, team photos
Background Considerations
The ideal background for trading cards:
- Simple and uncluttered β Green grass, blue sky, solid wall
- High contrast with subject β If jersey is dark, use light background
- Relevant context β Stadium, field, court adds atmosphere
Don't worry about busy backgrounds β CardStar's AI background removal tool can isolate the subject automatically.
Common Mistakes to Avoid
- Blurry photos β Use burst mode for action, tap to focus for posed
- Harsh shadows β Avoid direct midday sun; seek open shade
- Distracting backgrounds β Watch for poles "growing" out of heads
- Cropping too tight β Capture full upper body; you can crop later
- Low resolution β Never screenshot or download from social media (compressed)
- Dark photos β Face the light; expose for the subject, not background
