A Photomatix alternative built for the Apple ecosystem
Photomatix Pro has been the dedicated HDR merge tool since the early days of digital HDR photography, and it remains a capable, respected piece of software — especially for batch-processing real-estate work. MergeHDR takes a different approach built specifically for people whose photos live in Apple's Photos app: instead of importing brackets into a separate program, it finds them where they already are.
Photomatix Pro comes from HDRsoft, and by photo-software standards it's ancient in the best sense of the word — it has been continuously developed and sold for roughly two decades, long enough to become the default answer whenever "HDR software" comes up in a real-estate or landscape photography forum. It ships as a standalone application for Windows and Mac, with an optional plugin that hooks into Lightroom and Photoshop so a bracket set can be sent out for tone-mapping and brought back into the same catalog. That plugin workflow, plus a deep set of batch-processing tools and presets aimed squarely at high-volume shooters, is a large part of why it has stuck around as an industry default for real-estate photography specifically — a single operator can point Photomatix at a folder of hundreds of bracketed room shots overnight and come back to finished HDR images in the morning.
MergeHDR was built around a narrower but different problem. Most people who bracket exposures with an iPhone, a mirrorless camera, or a drone don't have a folder of files sitting on a desktop waiting to be imported — they have a Photos library on a Mac or an iPhone, with the bracket sets buried among everything else they've shot that week. MergeHDR reads the EXIF signature of an auto exposure bracket as it lands in that library and surfaces the set for merging, with no import step, no separate catalog to maintain, and no file management beyond what Photos already does. Everything runs on-device, on both the Mac and iPhone/iPad versions, as a Universal Purchase.
| MergeHDR | Photomatix Pro | |
|---|---|---|
| Platforms | Mac, iPhone, iPad (Universal Purchase) | Windows and Mac (desktop only) |
| iPhone/iPad app | Yes | No — desktop only |
| Finding your brackets | Automatic — detects AEB sets already in your Photos library | Manual — you import and select each set yourself |
| Where it lives | Native to the Photos library, no separate catalog | Standalone app, or a Lightroom/Photoshop plugin |
| Batch real-estate presets | Not the focus of the app | Strong — an industry-standard workflow for high-volume shoots |
| Processing | On-device, no uploads | Local processing, no uploads |
| Pricing | Free to try, then $19.99 once or $9.99/year | One-time license (Photomatix Pro) |
| Track record | New app, built for Apple-native workflows | In continuous development for roughly two decades |
Who should use which
Choose Photomatix Pro if you're a real-estate photographer or another high-volume shooter processing dozens or hundreds of tripod-based bracket sets in a session, want batch presets tuned for that kind of work, or your editing happens on Windows. Its plugin integration with Lightroom and Photoshop also matters if a desktop catalog workflow is already central to how you deliver finished images to clients.
Choose MergeHDR if your photos already live in Apple's Photos app and you'd rather not run a separate import ritual before every merge, if you shoot brackets on an iPhone or bring them in from a camera or drone and want them found automatically rather than hunted down by hand, or if an iPhone/iPad workflow matters to you — Photomatix has no mobile app at all. It also suits anyone who bracketed occasionally over months and now has scattered, unmerged sets buried in a large library, since MergeHDR surfaces every one of them without you having to remember which shoots had brackets.
The verdict
These aren't really competing for the same job. Photomatix Pro is a mature, purpose-built merge-and-tone-map engine with two decades of real-estate-industry trust behind it, and if that's your workflow, it remains a solid choice worth its one-time price. MergeHDR isn't trying to out-batch it — it's solving the much more common everyday problem of brackets that pile up unmerged in an ordinary Photos library because finding and importing them by hand is enough friction that most people simply don't. If that's your situation, automatic detection is the meaningful difference, not a longer feature list.
