Frequently Asked Questions
What is the golden ratio?
The golden ratio (φ ≈ 1.618) is a mathematical proportion found throughout nature and used in art for centuries. It creates harmonious, aesthetically pleasing compositions.
Should I always use golden ratio in my photos?
Not necessarily! The golden ratio is a guide, not a rule. Use it as a tool to improve composition, but don't let it limit your creativity. Many great photos break these "rules."
What's the difference between golden ratio and rule of thirds?
Rule of thirds divides the image into equal thirds (1:1:1), while golden ratio uses 1:1.618 divisions. Golden ratio is mathematically more precise but rule of thirds is easier to apply quickly.
Can I use this for video analysis?
Yes! Upload a screenshot or video frame to analyze composition. The principles apply to both photography and videography.
Is my image uploaded to your servers?
No! All processing happens in your browser. Your images never leave your device, ensuring complete privacy.
