2. What is the difference between optical and digital zoom?
Optical zoom uses physical lens movement for better image quality, while digital zoom crops and enlarges the image, reducing clarity.

3. What is computational photography?
Computational photography uses AI and software techniques like HDR, Night Mode, and multi-frame processing to enhance image quality beyond hardware limitations.

4. What are periscope zoom lenses in smartphones?
Periscope lenses use a prism and multiple lenses to provide high optical zoom (e.g., 5x–10x) without increasing phone thickness.

5. How does AI improve smartphone photography?
AI enhances images by detecting scenes, adjusting exposure, reducing noise, and applying real-time effects like portrait mode and night mode.

6. What is the role of image sensors in smartphone cameras?
Image sensors convert light into digital signals. Larger sensors capture more light, improving low-light performance and image quality.

7. What is pixel binning in smartphone cameras?
Pixel binning combines multiple smaller pixels into one larger pixel to enhance brightness and detail in low-light conditions.

8. What is the future of smartphone camera technology?
Upcoming advancements include quantum dot sensors, AI-driven photography, holographic imaging, and continuous optical zoom for professional-grade photography.
