Halide saves both RAW data and a JPG or HEIC image that can be easily shared with anyone. One downside is that third-party apps can only take RAW images at 12 megapixels on the iPhone, so there&rsquo;s no way to capture 24 or 48 megapixel Process Zero images.<\/p>\n<p>[&#8230;]<\/p>\n<p>Naturally, since Process Zero images don&rsquo;t take advantage of Night Mode, the pictures will look noisier. Halide suggests that users take pictures with manual controls to reduce the ISO for better results. Also, since Process Zero images don&rsquo;t have HDR, you need to make sure which object in the scene you want to adjust the exposure accordingly.<\/p>\n<\/blockquote>\n<p>See also: <a href=\"https:\/\/www.lux.camera\/process-zero-manual\/\">Lux<\/a>.<\/p>\n\n<p><a href=\"https:\/\/mastodon.social\/@cdevroe\/113124041196742747\">Colin Devroe<\/a>:<\/p>\n<blockquote cite=\"https:\/\/mastodon.social\/@cdevroe\/113124041196742747\">\n<p>I want to use Halide&rsquo;s Process Zero a lot more - perhaps all the time? But it only shoots raw and I&rsquo;d prefer JPG for most things mostly due to size.<\/p>\n<\/blockquote>\n\n<p>After trying out Process Zero for a while, I don&rsquo;t think it&rsquo;s really for me, though I will continue to use it for select shots where it&rsquo;s really important to have lots of editing options. The two main issues:<\/p>\n\n<ul>\n<li><p>Most of the time, I have no preference or prefer the non&#x2013;Process Zero photo. For my purposes, it&rsquo;s not worth the storage and trouble of creating multiple versions of each photo (one of them RAW) to see which I prefer. With older iPhones and iOS versions, I liked using <strong>Keep Normal Photo<\/strong> so I could easily have both HDR and non-HDR versions of each image, as often one was much better than the other, and the storage penalty wasn&rsquo;t huge. But Apple has removed that option&mdash;and no longer even lets me turn off HDR. Halide does have an option for using <strong>Apple Processed<\/strong> without <strong>Smartest Image Processing<\/strong>, but this needs to be chosen in the settings; it doesn&rsquo;t automatically save multiple versions of each photo.<\/p><\/li>\n\n<li><p>Using Halide alongside the regular Camera app doesn&rsquo;t seem to play well with iOS multitasking. As soon as I started doing this on hikes, my Gaia GPS tracks started getting holes in them where it would stop recording for a while.<\/p><\/li>\n<\/ul>\n\n<p id=\"halide-2-15-process-zero-update-2024-09-25\">Update (2024-09-25): <a href=\"https:\/\/x.com\/nubero\/status\/1839004222177563119\">Niko Kitsakis<\/a>:<\/p>\n<blockquote cite=\"https:\/\/x.com\/nubero\/status\/1839004222177563119\">\n<p>First picture is the mush that is Apple Pro RAW (what a joke).
