Award-winning camera app Halide Mark III has been updated to version 3.2, bringing dedicated support for iPhone 18 Pro by broadening user control over the device's new variable aperture camera system. Apple's stock Camera app lets iPhone 18 Pro owners choose from a four-stop variable aperture ranging from ƒ/1.48 to ƒ/4.0, delivering around 50 percent better low-light performance and giving users more optical control over depth of field.
