💡 Pro Tips for Perfect Crops
- Rule of Thirds: Imagine grid dividing image into 9 parts. Place important elements at intersections.
- Leave breathing room: Don't crop too tight around subjects unless required.
- Check edges: Ensure no unwanted objects at crop boundaries.
- Resolution matters: Cropping reduces image size. Start with high resolution.
- For faces: Keep eyes in top third for portraits.
❌ Common Cropping Mistakes
| Mistake | Why It's Wrong | Solution |
|---|---|---|
| Cropping at joints | Looks unnatural (cut at ankles, wrists) | Crop between joints or include full limb |
| Too much headroom | Subject looks small, wasted space | Position eyes in top third |
| No headroom | Subject touching top edge | Leave small space above head |
| Wrong aspect ratio | Image gets stretched when used | Use fixed ratio for specific platforms |
