Here's the difference the wider aperture of the iPhone 18 Pro makes

Key Points:
- The iPhone 18 Pro's main camera features a wider aperture of f/1.48 compared to the iPhone 17 Pro's f/1.78, enabling a shallower depth of field for portraits through optical background blur rather than computational effects like Portrait mode.
- A controlled test comparing photos taken at f/1.8 and f/1.48 showed that the wider aperture produces a noticeably stronger background blur, especially for closer background elements, enhancing subject separation.
- The difference in background blur becomes less pronounced with more distant background objects, and while subtle, the improvement is more significant than initially expected and can be beneficial in certain portrait situations.
- The test focused on head-and-shoulder portraits to maximize blur effects and controlled variables such as focal length, subject distance, and framing to isolate the aperture's impact.
- Beyond the wider aperture, the new lens's variable aperture offers additional manual control benefits, which will be explored in a subsequent review.
