A new update to Lux Optics’[anti\-algorithm Halide camera app](https://www.theverge.com/tech/875919/halide-mark-iii-process-zero-hands-on)for the[iPhone and iPad](https://apps.apple.com/us/app/halide-mark-iii-pro-camera/id885697368)adds two new photography looks and support for the variable aperture on the new[iPhone 18 Pro’s main camera](https://www.theverge.com/tech/995945/iphone-18-pro-max-review-camera-aperture)\. Halide isn’t the first alternative to the native iOS camera app to add support for the new feature, but it offers more finite control over aperture settings than other third\-party apps\. The iOS camera app limits aperture adjustments to just four presets, but both the[BlackMagic Camera and Moment Pro Camera II apps](https://www.theverge.com/tech/1000729/moment-pro-blackmagic-camera-ii-ios-app-iphone-18-pro-max-aperature-camera)expand that to 10 presets in 1/3 stop increments, similar to what most digital cameras offer\. Halide Mark III goes even further by letting you select any f\-stop setting from f/1\.48 down to f/4\.0\. Although it’s hard to imagine you’ll see any noticeable difference between f/4\.0 and f/3\.99, the option is available\. The Halide developers are also considering adding f\-stop presets in future updates based on user feedback\.

Today’s update adds a new Dawn look to the collection that applies “filmic warmth in the mid\-tones and highlights with gentle, rich shadows” and Quicksilver, which “pairs high contrast with muted color, inspired by silver\-retention processes\.” **Follow topics and authors**from this story to see more like this in your personalized homepage feed and to receive email updates\. - Andrew Liszewski
