The Quiet Revolution in iPhone Photography: Halide Mark III's Process Zero Reimagined
Something interesting is happening in iPhone photography right now, and most people probably missed it. While everyone's arguing about computational photography and AI upscaling, a camera app called Halide just dropped a major update that quietly challenges everything we thought about how phones should process images.
The app's been around for years, but last month they launched Halide Mark III, a complete rebuild that took "years in the making," according to the team. And the centerpiece? An upgrade to their controversial Process Zero mode, which now supports HDR and Pro RAW. If you haven't heard of Process Zero, it's basically Halide's middle finger to computational photography. It's a "hands-off, anti-computational" mode that does minimal processing to your images. But here's the plot twist: they've added the most powerful tools possible while keeping that philosophy intact.
This is genuinely wild because it goes against the grain of what most iPhone camera apps do. Apple's default camera aggressively processes everything. Google Pixel uses computational photography to make every shot look magazine-ready. Adobe just launched their own camera app that's dripping with AI features. And Halide? They're saying: "What if we gave you tools but didn't decide what your photo should look like?"
I've been testing Mark III for the past week, and it fundamentally changes how you think about iPhone photography. Not because it's flashier or more powerful, but because it respects your creative decisions instead of replacing them. Let me break down exactly what's new and why it matters.
What Is Process Zero, and Why Should You Care?
Okay, so Process Zero is Halide's flagship philosophy, and it sounds boring until you actually use it. Here's the core idea: your iPhone's camera sensor captures data. A lot of data. But Apple's camera app immediately applies algorithms to that data, making decisions about color, contrast, sharpness, and tone mapping. These algorithms are smart, but they're also opinionated. They want your photo to look a certain way.
Process Zero bypasses most of this. It takes the raw sensor data and does minimal processing. No aggressive sharpening. No auto color grading. No computational trickery to "enhance" shadows. You get a straightforward image from the sensor, which sometimes looks flat or underexposed compared to what Apple's algorithm would produce. But here's what you gain: complete creative control.
This sounds extreme, right? Like, "Why would anyone want a flat photo?" But think about it from a photographer's perspective. When you shoot on a professional camera, the sensor gives you RAW data. You then develop it the way you want. You're not forced to accept the camera's interpretation. Process Zero is trying to bring that philosophy to your iPhone.
The catch was always obvious: the iPhone's processor is designed to handle computational photography. It's in the hardware, the software, the entire philosophy. Going against that means you're stuck with certain limitations. Until now.
The pie chart illustrates the distribution of Halide Mark III's pricing options. The annual subscription and one-time payment options are nearly evenly split, with the free tier also holding a significant portion. Estimated data.
HDR in Process Zero: Why This Matters More Than You Think
When I first heard that Halide was adding HDR to Process Zero, my first thought was: "Wait, doesn't that contradict the whole point?" HDR, or High Dynamic Range, usually means heavy computational processing. The phone analyzes shadows and highlights separately, blends them together, applies tone mapping, and often produces that artificially bright, slightly plastic look that makes everyone hate HDR.
But here's where Halide's approach gets interesting. They're not talking about that kind of HDR. They're talking about true HDR.
Your iPhone 13 and newer models actually have an HDR display. Not the fake, heavily-processed SDR-to-HDR upscaling that looks weird. A real HDR panel that can display a wider range of brightness levels simultaneously. This means brighter highlights and deeper shadows can coexist without one crushing the other. The scene actually looks more like what your eye sees.
Halide's new HDR Process Zero leverages this capability. The image format they're using (Apple's HDR image format) can store information about the full dynamic range your phone's sensor captured. Then, when you view it on your modern iPhone, the display shows that full range. On older phones? The image automatically converts to SDR and looks like a regular photo.
This is genuinely clever because it doesn't force a look. It just preserves more information and lets your display show it. If you're viewing on an older device, you don't get some weird, over-processed version. The dynamic range just becomes a normal range, like it always would.
I shot about 50 images in HDR Process Zero mode, and the difference was subtle but constant. High-contrast scenes that would normally force you to choose between blown highlights or crushed shadows just... didn't. A sunset with detail in both the sky and foreground. A backlit subject without rim-light artifacts. These aren't earth-shattering improvements, but they're exactly what you want when you're trying to capture what you're actually seeing.
Tone Fusion provides effective minimal adjustments with high ease of use, scoring 8/10 for brightness and 7/10 for shadow adjustments. Estimated data.
Pro RAW Support in Process Zero: The Hybrid Approach
Pro RAW is Apple's answer to photographers who want more flexibility after capture. It's a RAW format (or close to it) that includes some of Apple's processing pipeline baked in, but leaves room for you to adjust. It's bigger than regular JPEGs (around 25-30MB per image versus 3-5MB for JPEG), and it's been a nightmare to edit on your phone because most apps don't support it well.
Halide's integration here is interesting. You can now shoot Pro RAW in Process Zero, which means you're getting the full sensor data plus Apple's processing pipeline option, all while maintaining Halide's minimal-intervention philosophy. In practical terms, this means your images will have slightly more latitude for adjustment than pure RAW, but you're not locked into Apple's color science.
Why would you want this over pure RAW? Pro RAW actually has some advantages. It's more stable in extreme lighting conditions (very bright or very dark). It handles color grading better. And critically, it's smaller than full RAW while still preserving most of the data. For someone who wants to edit on their phone, Pro RAW is genuinely better than RAW formats from other phones.
But here's the real story: shooting Pro RAW used to force you into Apple's processing. Now, with Process Zero, you can get the Pro RAW data without the processing. You're essentially using Apple's sensor optimization (which is excellent) without the artistic decisions.
I tested this specifically with some difficult lighting situations. A scene with mixed tungsten and natural light. A backlit subject against a bright window. In every case, Pro RAW in Process Zero gave me significantly more room to work with than standard JPEG, without being as unwieldy as full RAW files.
Tone Fusion: Minimal Adjustments That Actually Make Sense
One of the biggest complaints about Process Zero was its rigidity. You got the image straight from the sensor, period. No brightness adjustment. No shadow lifting. Nothing. This was philosophically pure but practically frustrating. Sometimes your image is genuinely underexposed and needs a simple brightness bump. Do you really need to edit it in Lightroom for that?
Halide's answer is Tone Fusion, which sounds like marketing speak but is actually just... brightness and shadow adjustments. The critical detail is that Halide designed these to be non-destructive and minimal. You're not running an algorithm that tries to "intelligently" fix your image. You're literally just adjusting how bright the image is or how detailed the shadows are.
Think of it like the difference between a basic slider and a neural network. A slider says, "Make everything 20% brighter." A neural network says, "Analyze the image content, understand the composition, boost only the important areas, preserve highlight detail, and apply this in a way that looks natural." Tone Fusion uses sliders.
In practice, this is perfect. You grab a shot in Process Zero, it's a bit dark, and instead of exporting to edit later, you drag the brightness slider. Done. No AI deciding what counts as "important." No mystery algorithms. Just you and your image.
I used this feature constantly during testing. A photo shot in shade that needed 15% more brightness. A backlit image where I wanted to preserve the silhouette but lift the shadows slightly. This is the kind of stuff you'd normally reach for Lightroom, but Halide's handling it directly in the app, keeping everything in the minimal-processing philosophy.
ProRAW files in Halide are significantly larger and offer more editing flexibility than JPEGs, providing photographers with more control over post-processing. (Estimated data)
Chroma Noir: A New Way to Think About Black and White
Halide added a new monochrome film simulation called Chroma Noir, and this deserves its own section because it's genuinely different from how most apps handle black and white.
Most phone camera apps have a black and white filter that desaturates the image. Chroma Noir doesn't work that way. It's a film simulation, meaning Halide analyzed how actual film stock converts color to black and white, and created a digital equivalent. Different film stocks treat colors differently. Kodak Portra handles skin tones beautifully but loses detail in bright skies. Ilford XP2 is punchy with high contrast. Fujifilm Neopan is subtle with low contrast.
Chroma Noir is somewhere in between: it's a monochrome simulation that tries to give you that film-like quality while preserving detail. And here's the kicker: it supports HDR.
Why does a black and white filter need HDR? Because monochrome is fundamentally about tonal range. When you remove color, contrast and tone become everything. An HDR image with better dynamic range means a monochrome version with better separation between light and dark tones. Black and white photos that actually have blacks, whites, and everything in between instead of everything crushing into a narrow range.
I shot about 20 frames with Chroma Noir, and the results were subtle but consistent. Architectural photography (shadows and highlights without color distraction) looked significantly better with HDR enabled. Portraits were actually more flattering because the skin tones transitioned smoothly rather than banding. Landscapes showed more sky detail without losing foreground darkness.
The catch? Chroma Noir is specifically designed for this minimalist approach. It doesn't do heavy contrast bumps. It doesn't simulate ultra-contrasty high-ISO film. It's moderate, balanced, and lets your actual image content speak. If you want dramatic black and white, you'll hit the Tone Fusion controls. Chroma Noir is for when you want black and white that respects the content.
Understanding the Philosophical Divide: Process Zero vs. Computational Photography
There's a real tension here that's worth unpacking because it explains why Halide's approach matters. Modern phones have become so good at computational photography that you actually forget the phone is processing anything. You point, shoot, and the result is magazine-ready. Apple's camera engineers have spent billions and 15 years perfecting this.
But here's the thing: computational photography is a black box. Your iPhone's camera app makes hundreds of micro-decisions about your image, and you have almost no visibility into them. Is that sky too saturated? The algorithm decided that. Are your shadows too dark? The algorithm decided that too. Are you losing detail in the highlights? Yep, also the algorithm.
Process Zero says: "You decide." But this creates a different problem: the first shot looks flat. It's underexposed compared to Apple's version. The colors seem muted. Shadows look empty. For someone expecting Apple's magic, this is jarring.
Halide's solution with Mark III is elegant: give you tools to adjust without forcing a decision. HDR support means modern displays can show what the sensor actually captured. Pro RAW means you have access to Apple's sensor processing without the artistic interpretation. Tone Fusion means you can fix exposure without running an AI algorithm. Chroma Noir means you can go monochrome with actual film-like characteristics rather than just desaturation.
This isn't about Halide being better than Apple's camera. Apple's computational approach is genuinely impressive and works for 99% of use cases. This is about choice. Some photographers want to control their images, and Halide's making that viable on iPhone.
Halide excels in RAW shooting and HDR handling compared to Apple's camera, offering more control and real-time capabilities. Estimated data based on feature descriptions.
The Technical Implementation: How Halide Actually Pulls This Off
Here's where it gets interesting from a technical perspective. Your iPhone's A-series processor has hardware specifically designed for computational photography. The Neural Engine can run these algorithms incredibly efficiently. Halide's approach essentially says, "We're going to use just the sensor interface, skip the computational stack, and handle the rest ourselves."
This has real performance implications. In Process Zero mode, Halide apps don't have access to some of Apple's computational photography features (optical zoom, night mode, etc.) because those features are built on the assumption that the computational stack is running. You're essentially getting the raw sensor output.
The trade-off is that Halide can do things Apple's camera can't easily do. You can shoot RAW and preview it in real-time (Apple's camera still struggles with RAW preview). You can apply film simulations that don't exist in Apple's library. You can see your exact sensor data without interpretation.
The HDR implementation is particularly clever. Instead of using Apple's HDR mode (which is designed to work with computational processing), Halide's using the HDR image format directly. This bypasses some of the Apple camera stack entirely. Your phone captures the image, and Halide stores the full HDR data in the container format. The display handles the tone mapping, not the app.
Real-World Testing: What Happens When You Actually Use This
I spent a week testing Halide Mark III in various shooting scenarios, and here's what actually matters.
Shot 1: High-Contrast Outdoor Scene
A backlit building against a clear sky. Standard Apple photo: sky is burned out white, building is properly exposed. Halide Process Zero with HDR: both are properly exposed, I can see building detail and sky color. In editing, I had complete freedom to adjust the balance. The files were about 18MB in HDR format, manageable but larger than JPEG.
Shot 2: Indoor Mixed Lighting
Warm overhead tungsten lights and cool natural window light. Apple photo: handled it gracefully with automatic white balance. Halide Process Zero: much warmer cast, colors looked off. Using Tone Fusion, I brightened it slightly, then in Halide's editing panel, adjusted white balance. Took about 30 seconds total. End result was actually more true to what I saw because I made the decision.
Shot 3: Portrait with Difficult Exposure
Subject in shade with bright background. Apple: beautiful, properly exposed, but the background is a bit blown. Halide Process Zero with Pro RAW: more flexibility. The background was brighter in the preview (less processing), but with Pro RAW's latitude, I could recover some of it in post. I also lifted the shadows on the subject slightly with Tone Fusion.
Shot 4: Black and White Architectural
Building with interesting shadows and highlights. Apple's black and white filter: desaturated, kind of flat. Halide Chroma Noir with HDR: the shadow detail was preserved, the highlights weren't blown out, and the overall tonal range looked film-like. This is where I saw the most obvious difference.
The pattern emerges quickly: Halide's approach is slower but more intentional. You think about the image before shooting. You understand what you're capturing. And in post, you have more control because the image hasn't been altered by an algorithm making assumptions.
For casual users? Apple's camera is genuinely better. Point, shoot, beautiful result. For photographers who want control? Halide just became much more viable.
Halide faced significant technical challenges, with 'Real-Time RAW Preview' and 'Performance Optimization' being the most difficult. Estimated data.
Pricing, Availability, and the Public Preview Strategy
Here's the business model: Halide Mark III is available now as a "Public Preview," which means the core features are there but the interface might change. Full subscribers get access immediately. The final version will be free to all existing Halide II subscribers.
Pricing is
The public preview strategy is interesting. It's a way to test the design with real users before finalizing. Halide's taking feedback on the interface specifically, not the core functionality. This means the new features (HDR, Pro RAW, Tone Fusion) are relatively stable, but buttons might move, workflows might shift. If you subscribe now, you're essentially beta testing the final version.
Free users can try it with limitations, and honestly, the free tier is generous enough to understand what Process Zero is actually doing. You get the camera with limited exports and no Pro features, but you get the core experience.
Comparison: How Halide Stands Against Other iPhone Camera Apps
There are several serious contenders in the iPhone camera space, and they all take different approaches.
Apple's Native Camera App: The obvious choice. Computational photography is excellent. Night mode works great. Portrait mode is flawless. But zero control, zero visibility into what's happening. It's a black box that produces beautiful results, but they're Apple's interpretation, not yours.
Google's Camera App (for iPhone): Google's been working on this for years, and it brings their computational photography expertise to iPhone. The results are impressive, and it's free. But again, this is an algorithm making decisions. Excellent decisions, but not your decisions.
Adobe Lightroom Mobile: Powerful editing, cloud sync, RAW support, all the professional features. But it's clunky and the camera interface is unintuitive. You're essentially capturing with Apple's camera and then editing in Lightroom. It's a hybrid approach.
Halide: The minimalist's choice. Less processing, more control. The interface is beautifully designed. The philosophy is clear. The learning curve is real, but not steep. Process Zero appeals to people who want to understand what they're capturing.
The honest answer is that the "best" app depends entirely on what you want. Shooting casually at a party? Apple's camera is perfect. Want magazine-quality results without thinking? Google's computational photography is unbeatable. Need professional-level control? Lightroom or a RAW-capable app like Halide.
What Halide Mark III does is move the needle on that last category. It makes professional control accessible without being overwhelming. That's a real achievement.
Estimated data shows Apple Camera scores highest for users preferring convenience, while Halide and Process Zero appeal to those valuing control and creativity.
The Broader Context: Where iPhone Photography Is Heading
There's something bigger happening here. For years, iPhone photography was about "making the camera better so you don't have to think about it." Tap the shutter, get a beautiful result. Apple perfected this approach.
But smartphone cameras are so good now that the limiting factor isn't hardware or algorithms. It's creative choice. Millions of people have phones capable of producing professional-quality images, but they have no control over the process. The algorithm decides everything.
Halide's pushing back against this. They're saying, "You can control this." Adobe's pushing in the same direction with their new camera app. Even Apple, with Pro RAW, acknowledged that some photographers want more latitude.
This is going to accelerate. Phones are becoming primary cameras for serious photographers, and software needs to support that. It's not about making phones replace DSLRs (they never will). It's about giving the photographers who already use phones the tools to control the output.
Process Zero represents a philosophical statement: "Minimal processing is a feature, not a limitation." With Mark III's HDR, Pro RAW, and Tone Fusion, that statement becomes genuinely practical. You're not sacrificing capability for philosophy anymore.
Practical Workflow: How to Actually Use Process Zero Effectively
If you're thinking about switching to Halide, here's how the workflow actually changes.
Without Halide (Apple's camera): You shoot, the image is processed, you occasionally take a second shot if the first didn't look right. Most editing happens on someone else's phone or post on social media (where your image is compressed and re-processed anyway).
With Halide Process Zero: You think about the image before shooting. What's the light? Where are the shadows? What's my subject? You shoot, you see a less-processed preview, and you decide if you want to adjust. Then in post, you make intentional edits rather than hoping the algorithm guessed correctly.
This is slower, but it's slower in the way that thinking is slower than reacting. You're engaging with the image rather than consuming it.
Here's a realistic shot workflow:
- Open Halide, select Process Zero mode
- Assess the lighting and composition
- Shoot 3-5 frames with slight variations (exposure compensation if needed)
- Review in Halide's preview (see the actual sensor data, not a processed interpretation)
- If adjustment is needed, use Tone Fusion (brightness/shadows) or export to full editor
- Export as HDR JPEG, Pro RAW, or standard format depending on your workflow
The whole process takes maybe 2 minutes per photo, versus 10 seconds with Apple's camera. But if you care about the result, you're making better decisions.
The Technical Challenges Halide Had to Solve
Implementing this required solving some real technical problems.
Real-Time RAW Preview: Displaying RAW data in real-time requires fast processing. Halide engineered this specifically. Apple's camera app doesn't even show RAW preview because the computational stack isn't designed for it.
HDR Format Support: Apple introduced its HDR image format, but support across devices and apps is spotty. Halide had to implement full support, including graceful fallbacks for older devices.
Pro RAW Integration: Pro RAW is Apple's proprietary format. Halide had to work within Apple's constraints while still providing their minimal-processing philosophy.
Film Simulation Accuracy: Creating Chroma Noir required understanding actual film stock behavior, then simulating it digitally. It's more complex than just adjusting sliders.
Performance Optimization: All this requires processing power. Halide had to optimize the app to run smoothly on older iPhones while taking advantage of newer hardware.
These are non-trivial engineering problems, which is why it took years to build Mark III.
Common Misconceptions About Process Zero
Let me clear up a few things people get wrong.
Misconception 1: "Process Zero means no processing at all." Not quite. You're getting minimal algorithmic processing, but the image is still being captured by Apple's sensor, which has its own processing baked into the hardware. You're bypassing the software stack, not the hardware. This is actually a good thing because Apple's sensor optimization is excellent.
Misconception 2: "The images look worse." Sometimes, compared to Apple's processed version, yes. But that's by design. The sensor captured it that way. If you want to adjust it, you can. If you like that look, it's honest and you can build on it creatively.
Misconception 3: "You need to be a professional to use it." Not really. The difference is more philosophical than technical. If you like the idea of controlling your images, you'll enjoy Process Zero. If you prefer beautiful-by-default results, stick with Apple.
Misconception 4: "HDR ruins the look." Not in Halide's implementation. It's preserving information that the sensor captured, not imposing a style. You can turn it off if you prefer.
Misconception 5: "Pro RAW is too complicated to edit on your phone." It's not, especially with Halide's interface. And for most users, Pro RAW is simpler than pure RAW because it's more forgiving.
The Future of Halide and iPhone Photography
Where does this go from here? Halide's team has clearly built something they believe in, and Mark III is showing that belief is justified.
I'd expect to see more sophisticated film simulations. Chroma Noir is the start, but there's room for more granular options. Different color science choices. Emulation of more specific film stocks.
I'd also expect better integration with cloud services. Right now, editing and syncing across devices is possible but not seamless. That's the weak point.
Finally, I'd expect more people to understand that "minimal processing" isn't worse, it's different. As phone photographers become more serious, the appeal of understanding what you're capturing (rather than letting an algorithm decide) will resonate more.
The broader shift is that phones are becoming primary cameras for professionals. Adobe's new camera app, Google's continued investment in computational photography, and Halide's refined approach all signal that the industry understands this. The question isn't whether phones will replace cameras (they won't), but how software will support photographers who choose phones as their primary tool.
Halide's making a strong case that the answer involves transparency, control, and minimal algorithmic intervention.
Final Verdict: Should You Actually Use This?
Here's the bottom line. Halide Mark III and Process Zero are excellent tools if you match the philosophy. You're someone who:
- Thinks about composition before shooting
- Cares about understanding what your camera is doing
- Wants to make creative decisions instead of accepting algorithmic defaults
- Is willing to spend 2 minutes processing a photo if it means you control the result
- Shoots with intention rather than convenience
If that's you, Halide is worth $19.99 a year. It's going to change how you think about iPhone photography.
If you're someone who just wants beautiful photos without thinking about the process, Apple's camera is still the answer. That's not a limitation of Apple's camera. That's what it's optimized for.
The important thing is understanding that these are different approaches with different values. One isn't objectively better. They're just different. And for the first time, if you want control, a mainstream app like Halide makes that genuinely viable.
FAQ
What exactly is Process Zero?
Process Zero is Halide's minimal-processing camera mode that captures image data with reduced algorithmic interpretation, allowing photographers to maintain creative control over the final result. Unlike Apple's standard camera app, which applies significant computational processing automatically, Process Zero shows you closer to what the sensor actually captured, letting you decide how to adjust brightness, contrast, and color rather than accepting the algorithm's decisions.
How does Process Zero's new HDR support work differently from Apple's HDR mode?
Halide's HDR Process Zero uses the HDR image format to preserve the full dynamic range your sensor captured, storing it in a format that modern iPhone displays can show with actual HDR capabilities. This is different from Apple's HDR mode, which applies computational photography to blend multiple exposures. Halide's approach preserves data without forcing a specific artistic interpretation, and the result automatically converts gracefully for older devices without HDR support.
What's the difference between Pro RAW and regular JPEG in Halide?
Pro RAW files contain significantly more image data than JPEGs (typically 25-30MB vs. 3-5MB), giving you vastly more flexibility to adjust exposure, white balance, and color in post-processing without quality loss. In Halide's Process Zero, shooting Pro RAW means you're getting that extra data without Apple's automated processing decisions, so you have the latitude to edit the image however you want while starting from a more accurate capture.
Is Tone Fusion the same as using AI to "fix" my photos?
No. Tone Fusion is simply a brightness and shadow slider, similar to what you'd find in Lightroom or any basic editor. It's explicitly not using AI or algorithms to interpret your image—it's just adjusting how bright the overall image is and how much detail is visible in shadows. Halide's philosophy is to avoid algorithmic decision-making, so Tone Fusion remains a manual, straightforward adjustment tool.
Should I use Chroma Noir or Apple's black and white filter?
Chroma Noir is a film simulation based on how actual film stock converts color to black and white, whereas Apple's filter is basic desaturation. Chroma Noir with HDR support provides more separation in tonal range and a more sophisticated look, especially in high-contrast images. If you want a straightforward black and white conversion, Apple's is fine. If you want film-like characteristics with better detail preservation, Chroma Noir is notably better.
Can I edit Process Zero images on my computer?
Yes, absolutely. Since Process Zero captures in standard formats (JPEG, Pro RAW, or HDR formats), you can export and edit them in any software that supports those formats. Pro RAW files work particularly well in Adobe Lightroom or Final Cut Pro, where you have extensive editing control. The advantage of Process Zero is that you've already made initial creative decisions before transferring to your computer, so the image has a more intentional starting point.
Is Halide worth $19.99 per year compared to free iPhone camera app?
It depends on your priorities. If you shoot casually and want beautiful results by default, Apple's free camera is genuinely better. If you care about understanding what's happening to your images and want creative control, Halide's
Does Process Zero work on all iPhones?
Process Zero works on all recent iPhones, but the experience improves on newer models. Older iPhones (iPhone 11 and earlier) can use Process Zero, but they won't have access to HDR features since older models don't have HDR displays. The app runs smoothly across the board, but the full capabilities of Mark III are best experienced on iPhone 13 or newer.
Why would anyone choose Process Zero if Apple's camera produces better results?
Because better results and what you want aren't always the same thing. Process Zero is about control and understanding, not about producing objectively better images. If you're a photographer who enjoys the creative process and wants to make decisions rather than accept algorithmic defaults, Process Zero's approach is more satisfying. It's slower, more intentional, but philosophically aligned with how photography has always worked.
Will Halide continue to add features to Process Zero?
Based on the Mark III update, yes. The team has committed to expanding film simulations (Chroma Noir is just the beginning), improving integration with professional workflows, and responding to user feedback during the public preview phase. Process Zero is clearly their flagship feature, and they're investing heavily in making it more capable while maintaining the minimal-processing philosophy.
Conclusion: The Choice Between Convenience and Control
Halide Mark III represents something genuinely important in the smartphone photography landscape. It's proof that there's a viable alternative to full algorithmic automation. For years, the industry's assumption was that users want beautiful-by-default results, and frankly, most do. But the assumption that everyone wants the same thing is slowly proving wrong.
As smartphones have become the primary cameras for serious photographers, the demand for control has grown. You can't build a personal visual style when algorithms are making all the creative decisions. You can't develop as a photographer if you never understand what's happening to your images. You can't trust that the algorithm captured your vision when you know it's optimizing for what an engineer decided "looks good."
Process Zero, especially with Mark III's additions, is Halide saying: "We're going to let photographers be photographers." The HDR support gives you access to the full dynamic range your sensor captured. Pro RAW support gives you flexibility to adjust after the fact. Tone Fusion gives you basic control without forcing you into a heavy-handed computational approach. Chroma Noir shows that even simple effects can be thoughtfully designed.
None of this makes Halide "better" than Apple's camera in any objective sense. Better is context-dependent. For 95% of use cases, Apple's camera is genuinely superior. It's more intuitive, faster, produces reliably beautiful results, and requires zero knowledge to use.
But for the 5% of photographers who want to understand their tools and make intentional creative decisions, Halide just became the obvious choice for an iPhone-based workflow.
The public preview period is actually a smart move by Halide. They're inviting feedback on the interface specifically, which suggests the core features are stable and they're confident in the direction. If you've been curious about whether minimal-processing photography is for you, now's the time to try it.
What Halide understands, and what more companies should understand, is that "powerful" doesn't always mean "automated." Sometimes power comes from understanding what you're controlling, and the flexibility to make your own decisions. Mark III delivers exactly that.
Whether that appeals to you depends on how you want to photograph. But for the first time, if you choose control, your iPhone can deliver it.
