iPhone 18 Pro Gets 10-Step Aperture Control in Third-Party Apps

Moment Pro Camera II and Blackmagic Camera for iOS support the iPhone 18 Pro's variable aperture with 10 presets from f/1.48 to f/4.0 in 1/3-stop steps, which adjust light in small increments. Apple's developer kit enables this finer control, including options between the built-in iOS settings.
