Tyler Stalman reviews iPhone 18 Pro variable aperture and texture controls

The iPhone 18 Pro introduces a variable aperture system, which Stalman identifies as the most significant camera upgrade this year. This hardware change allows the wider f/1.48 aperture to let more light reach the sensor. The practical consequence is a lower ISO requirement in low-light conditions, which reduces the need for the software-based Night mode.

Stalman points out that Apple’s implementation of the aperture is mechanically distinct from traditional camera lenses. The aperture blades are positioned above the primary lens element rather than deeper inside the lens assembly. This unusual placement is visually documented in the review with close-up shots of the iris mechanism opening and closing.

Beyond the hardware, the review covers software updates including expanded Photographic Styles with new texture controls like Soft Skin, Glow, and Film. Stalman demonstrates these effects by adjusting their intensity from 0 to 100. He notes that while the Film effect’s grain and halation are impressive, he wishes for more granular control over the grain amount.

The review also addresses the new AI-powered editing tools, specifically Clean Up, Extend, and Reframe. Stalman acknowledges that these tools are technically impressive and convincing. However, he warns that they can make such significant changes to an image that the resulting photo no longer feels authentic to the original capture.

Stalman also offers practical advice for professional photographers regarding the device's physical finish. He notes that the previous year's Cosmic Orange color tended to appear in reflections when shooting through windows. For this reason, he suggests that pro photographers stick to Burgundy or Black to avoid casting unwanted color into their photos or videos.
