This is a major update of Acorn, and is currently on a time-limited sale for $19.99. It’s still a one time purchase to use as long as you’d like, and as usual, the full release notes are available. I want to highlight some of my favorite things below.

“Select Subject”, “Mask Subject”, and “Remove Background” are new commands which use machine learning (or A.I. if you prefer) to find the most important parts of your image, and then perform their respective operations. This has been a request for a long time, and while I was doubtful of it’s utility, it’s actually pretty fun to play with and more useful than I figured it would be. So I’m glad I took the time to integrate it.

You can now set your measurement units to inches, centimeter, or pixels, and it shows up across the tools for your image, not just specific ones. This includes the crop palette, shape dimensions, filter settings… well, pretty much everything. This might be the oldest feature request I’ve implemented so far. And then related to this, Acorn 8 now has an on canvas ruler which you can use to measure out distances, straighten your image with, or even redefine the DPI.

Look up Table (LUT) support. LUTs are pretty fun, and they work by mapping one set of colors to another, enabling consistent or stylized visual effects. LUTs are used primarily in photography or filmmaking, and you can download and install new LUTs from various places across the internet.

And more, so much more. The release notes are copious, and for me, always interesting. Acorn remains one of my most-used tools. It’s fast, reliable, powerful, extensible/scriptable, and the interface makes so much intuitive sense. That’s all been true since version 1.0 back in 2007, and that’s why it’s been my go-to image editor since it was in early beta before version 1.0 back in 2007. It’s just faster and more powerful today.

Acorn is, simply put, one of the best Mac apps ever made. It’s that good. You’re nuts (sorry) if you don’t check it out while it’s available for just $20.

Blackmagic Design:

Blackmagic Design announced it will start taking pre-orders for the new Blackmagic URSA Cine Immersive camera — the world’s first commercial camera system designed to capture Apple Immersive Video for Apple Vision Pro — today with deliveries due to start in early 2025. DaVinci Resolve Studio will be updated to support editing Apple Immersive Video early next year, offering professional filmmakers a comprehensive workflow for producing Apple Immersive Video for Apple Vision Pro. Apple Immersive Video is a remarkable 180-degree media format that leverages ultra-high-resolution immersive video and Spatial Audio to place viewers in the center of the action. [...]

Blackmagic URSA Cine Immersive features a fixed, custom lens system pre-installed on the body, which is designed specifically to capture Apple Immersive Video for Apple Vision Pro. The sensor delivers 8160 × 7200 resolution per eye with pixel level synchronization and an incredible 16 stops of dynamic range, so cinematographers can shoot 90fps 3D immersive cinema content to a single file. The custom lens system is designed for URSA Cine’s large format image sensor with extremely accurate positional data that’s read and stored at time of manufacturing. This immersive lens projection data — which is calibrated and stored on device — then travels through post production in the Blackmagic RAW file itself.

$30,000 — not cheap, but not crazy. And this isn’t merely 3D in a rectangular frame — it’s 180° 8K 3D.

David Smith:

What really intrigues me about it is when/if it will show up for rental. I have a few tentative ideas in this space I’d love to explore but I don’t think would justify the cost of owning one.

Looks like Lensrentals rents a vaguely similar, traditional Blackmagic camera kit for around $1,000/week ... which would make experimentation much more accessible.

I’m in the process of migrating from XCTest to Swift Testing. The basic stuff is pretty easy to translate, and in many cases I don’t even need to change the code inside my test methods. I’ve long been writing what Swift Testing calls expectations in terms of my own helper functions such as eq(), unwrap(), […]

Paul Kafasis, on the Rogue Amoeba blog:

Even as our products steadily grew in popularity, our relationship with Apple was almost non-existent. Plenty of individuals inside the company were fans, but we received very little attention from Apple as a corporate entity. We didn’t much mind being outsiders, but it meant that we often had zero notice of breaking changes introduced by Apple.

During this time, Apple placed an emphasis on improving the security of MacOS, continually locking the operating system down further and further. Though their changes weren’t aimed at the legitimate audio capture we provided our users, they nonetheless made that capture increasingly difficult. We labored to keep our tools functioning with each new version of MacOS. Through it all, we lived with a constant fear that Apple would irreparably break our apps.

In 2020, the disaster foreshadowed literally one sentence ago struck. Beta versions of MacOS 11 broke ACE, our then-current audio capture technology, and the damage looked permanent.

Kafasis is a friend and frequent guest on The Talk Show (and holds his own as a podcast co-host with a combustible collaborator), and I use quite a few apps in Rogue Amoeba’s suite, so I was familiar with the broad outline of this saga. But seeing it all spelled out made clear it was a lot more precarious than I thought.
