These camera apps give you more control over the iPhone 18 Pro’s aperture

Third-party camera apps now offer finer control over the iPhone 18 Pro's aperture than the native app.

The iPhone 18 Pro's native camera app offers limited manual control over its variable aperture, restricting users to four settings: f/1.48, f/1.8, f/2.8, and f/4. However, third-party developers can access more granular control through Apple's SDK. Blackmagic Design's free Blackmagic Camera app was among the first to enable finer aperture adjustments, offering 10 presets. Following this, Moment released an update for its $12.99 Moment Pro Camera II app, also providing 10 aperture presets adjustable in 1/3 stop increments from f/1.48 to f/4.0. While the practical difference in depth of field on the iPhone's small sensor may be subtle for such fine adjustments, the increased control is now available to users through these alternative applications.

The introduction of more granular aperture control in third-party iPhone apps signals a potential fragmentation in mobile photography capabilities, where advanced features previously exclusive to dedicated cameras are becoming accessible on smartphones. This move empowers users with greater creative flexibility, allowing for more precise adjustments to depth of field and exposure beyond the limitations imposed by native software, which could influence the development of future mobile camera hardware and software features.

This increased accessibility to finer aperture control could also foster a more competitive market for advanced mobile photography apps, pushing developers to innovate further and potentially lowering the barrier for professional-level mobile photography. As more apps adopt these granular controls, users might begin to expect this level of customization as standard, influencing Apple's own native app development and the broader smartphone camera industry's trajectory towards offering more sophisticated, user-adjustable features.
