📰 What Happened
The iPhone 18 Pro's main camera has a variable aperture. That means the hole that lets in light can change size. Apple's own camera app only offers four settings in manual mode, from f/1.48 to f/4.
Two other apps now do more. Blackmagic Camera is free, and version 3.5 added ten aperture presets. Moment Pro Camera II costs $12.99 and lets you pick from f/1.48 to f/4.0 in small 1/3-stop steps, like a normal camera.
🔍 The Backstory
The aperture controls how much light reaches the sensor and how blurry the background looks. Phone cameras kept a fixed aperture for years because space inside is so tight. Apple's tools for app makers always allowed finer control than its own app shows.
An early test called the Blackmagic feature 'pretty buggy'. A later update promised better speed and stability.
🎯 Why It Matters
Phone photographers who want more control now have it. With such a small sensor, though, the change in background blur may be hard to see.
