What happened when my M1 Max MacBook Pro met a $60,000 camera

When Apple launched its latest line of MacBook Pros with the new M1 Max chips, I was excited, as a professional photographer, by the upgrades and what that could mean for working creatives. The 16-inch model with an M1 Max CPU impressed CNET’s Dan Ackerman so much it earned a coveted Editors’ Choice award.

So when I got one in my hands, I wanted to see how well it copes with a demanding professional photoshoot workload. 

I put the top-end 16-inch Pro with the M1 Max chip with 64GB of RAM to the test in a studio photoshoot with probably the world’s best — and most demanding — camera. It’s the Phase One XFIQ4, a commercial-standard medium format camera that churns out whopping 150-megapixel images and costs somewhere north of $60,000. This beast is in the hands of elite professional commercial photographers the world over, and its stunning, detailed images would be a great test for the M1 Max chip.

I put together an ambitious product photoshoot of a “technology stir fry” showing a variety of tech products being tossed in oil in a wok above roaring flames. It involved shooting all the different elements individually, then piecing together numerous images from the camera into the single, finished shot seen above. This kind of compositing work can be demanding on a system, especially when working with multiple high-resolution layers. 

The finished image was made of 28 full-resolution images, loaded into a single document in Photoshop, each one with its own masking, adjustments and other effects. In short, it’s a behemoth of a Photoshop document, clocking in at almost 11GB in size. 

Anecdotally, working on the MacBook Pro felt swift. The camera was tethered over USB-C and the images were taken, imported and initially adjusted in Phase One’s own Capture One Pro software, which has been optimized for Apple’s M1 chips. It was zippy, with no noticeable lag when making adjustments to the images or when flicking between the shots I’d taken, despite their size. This alone was a relief, as some of my product photoshoots can involve taking hundreds upon hundreds of images and any slowdown from the machine can be frustrating.

I initially exported 45 full-resolution images (in Phase One’s .IIQ format), which I loaded into an image stack in Photoshop. On the M1 Max MacBook it took 2 minutes, 44 seconds to load the images into the document. I did the same thing using the older 13-inch M1 MacBook Pro (a 2020 model with 16GB of RAM) and it struggled, crashing multiple times before eventually taking almost exactly 5 minutes to load the stack. 

I then tried the same import test with a 2019 16-inch, Intel Core i9 MacBook Pro with 64GB of RAM, which took 4 minutes, 43 seconds. It should be noted that this MacBook is my work-provided one, and as such has a variety of security applications running in the background that could affect its performance. 

Once loaded, I selected the layers and used the Auto-Align tool to ensure all the images lined up with each other. It’s a demanding process but one that I use regularly for product photography, so efficient performance here is essential for my workflow. The M1 Max model took 6 minutes, 24 seconds to align the layers, the 16-inch Intel model took 7 minutes, 15 seconds while the 13-inch M1 model took a whopping 18 minutes, 20 seconds to complete the same task.  

The M1 Max MacBook handled the rest of the edit without any issue, allowing me to zoom in and out without lag or showing any real signs of slowing down. I ended up deleting some layers to get down to the 28 that made up the final image, yet even with every layer having its own masks and effects, the machine coped admirably with the edit process. 

My next test involved a focus stack of an image of an iPhone I shot with the Phase One camera. Focus stacking involves taking separate images of an object at different focus points before merging those shots to achieve pin-sharp focus from front to back. As with layer aligning, it’s a demanding task for the processor. You can see the full breakdown below of times it took each MacBook to load the 12 individual 303MB DNG (Adobe Digital Negative raw) files into an image stack, align the images and then focus stack in Photoshop, but the M1 Max was way ahead of the others on every single test, with the focus stacking tool in particular seeming to benefit from the M1 optimizations in Photoshop.

Arguably that should come as no surprise, given that it’s the latest model and it’s running Apple’s top-performing processor with the highest amount of RAM you can get it with. But pro photographers are a demanding bunch and time is money in a busy studio, so it’s good to know the extra investment for the M1 Max will indeed result in faster and more efficient work.
