Daniel Kennett in A Lament For Aperture, The App We'll Never Get Over Losing (also note an alt title in the URL):

Start spending time in the online photography sphere and you’ll start to notice a small but undeniable undercurrent of lament of its loss to this day. Find an article about Adobe hiking their subscription prices because they added AI for some reason, and amongst the complaining in the comments you’ll invariably find it: “I miss Aperture.”

Kennett goes deep into two specific details: the HUD-like UI that travels to the photo, and the technically impressive loupe. It’s worth checking it out just to reflect on the importance of execution; ostensibly those features exist in Adobe’s Lightroom (Aperture’s main competitor), Photos, etc. But Aperture designed them in particularly memorable and impressive ways.

Back in the early 2010s I used Aperture, too. I was rooting for it. I felt like it was designed, and Lightroom merely existed.

It reminded me of the 1990s when I felt the same about Netscape 4 over Internet Explorer 4. There was something about Netscape’s feel that appealed to me more. The way buttons were designed. The way they responded to clicks. The way pages loaded. All these little nuances. This was perhaps the first time I appreciated one app over another for things I didn’t know how to measure, or perhaps even describe.

Aperture vs. Lightroom feels like a similar story, because for all my appreciation for Aperture, I remember it being slower than Lightroom, and the noise reduction (much more important 10+ years ago) was worse, too. In a small way, it was a relief that Aperture was discontinued, because it saved me from a tricky choice: better designed vs. technically superior.

But: I miss Aperture. Maybe it would’ve caught up technically today and it would’ve been the best of both worlds. To this day, I use Lightroom (now Lightroom Classic). If it’s filled with UI quirks, it’s mostly bad ones. If there is beauty in it, I no longer know how to see it. It’s a tool in the most reductive sense of the word. My photos deserve more.

Also something I learned from Kennett:

“Shoebox” apps are apps that contain the content you use with them, as opposed to document-based apps which work with content you manage as a user. It’s an extremely common design nowadays, but less so back then — early pioneers of the shoebox app were iPhoto, iMovie, etc.
