Apple’s iPhone 18 Pro and Pro Max debut a genuine variable aperture and new manual controls, marking a significant camera overhaul focused on photo authenticity and enhanced video features.

A Reference Image system is introduced to verify photo integrity, with plans to add SynthID watermarking to flag AI-related edits and protect against manipulation.

Industry durability concerns are raised about mechanical variable aperture hardware, noting past instances where rivals dropped such features due to durability and production challenges.

The phone features a 48MP main camera with a physically adjustable aperture using six laser-cut blades that switch across four settings to improve low-light performance and background clarity in group shots.

A new Pro controls panel in the Camera app offers manual aperture, shutter speed, and white balance, plus a histogram to help users gauge exposure.

Apple Reference Image cryptographically signs sensor data and processes it via Private Cloud Compute to create an unalterable reference image stored with the original for reliable edit verification.
