In May, Lux Optics launched the all-new Halide Mark III pro camera app for iPhone. Today, Halide is back with its first update for iPhone 18 Pro, plus new features for all iPhone photographers.
Halide Mark III is all about enabling iPhone users to take better photos. It includes a redesigned camera, a new photo editor, and Halide Looks, which give your shots specific styles.
Halide 3.1 arrived in July, building on the original release with an additional Halide Look and more. Now Halide 3.2 is here, and it’s ready for the upgraded iPhone 18 Pro camera system.
Aperture Priority Mode
Halide 3.2 introduces Aperture Priority mode for iPhone 18 Pro, building on the app’s existing ability to select any f-number between ƒ/1.48 and ƒ/4.0. For reference, the built-in Camera app supports automatic variable aperture mode, or manually selecting ƒ/1.48, ƒ/1.8, ƒ/2.8, or ƒ/4.0.

With Aperture Priority mode, you set a target f-number and Halide automatically adjusts the shutter speed and ISO to suit the shot. Fully manual mode also enables direct ISO control.
New Halide Looks: Dawn and Quicksilver
Halide 3.2 adds two new Looks available for all iPhones: Dawn and Quicksilver. Dawn “offers filmic warmth in the mid-tones and highlights with gentle, rich shadows,” while Quicksilver “pairs high contrast with muted color, inspired by silver-retention processes.”
The update also introduces a 16:9 aspect ratio shooting mode.
Halide Mark III can be purchased outright for $69.99, or subscribers can access the app for $19.99/year.
