iPhone 15 Pro Max is built from aircraft-grade titanium that is both strong and lightweight, making it Apple’s lightest Pro model ever. The new design also uses curved edges and adds a customizable operation button for users to customize their iPhone experience. Officials say the camera upgrade brings the ultimate image quality equivalent to 7 Pro-level lenses, including a more advanced 48-megapixel main camera that supports a new 24-megapixel ultra-high default resolution; a new generation of portrait functions brings focus and depth of field Controls; improvements to Night Mode and Smart HDR
