Part 1
The video explains the difference between optical zoom (using a lens’s focal length) and digital zoom (cropping an image). Optical zoom maintains quality and compresses backgrounds to isolate subjects. Digital zoom, common on smartphones, enlarges pixels and significantly degrades image quality. The core advice is to physically move closer instead of relying on digital zoom.
Part 2
This video analyzes smartphone zoom: cropping a 64MP photo loses quality. Digital zoom also deteriorates quickly. A clip-on lens provides optical zoom and better quality, but is often impractical due to handshake and vignetting. For best results, physically get close to your subject first. Limit digital zoom to minimal amounts.
