What is it the other half of the time? I've been thinking of picking up a GRIII for my trip to Japan this summer, but I'm open to other ideas.
I personally almost always find phone photos to be woefully inadequate for even light editing, mostly because they turn into a blurry mess as soon as you crop even a little bit or want to print/look on a large screen.
I recently found a pic from behind-the-scenes of an old favorite movie of mine. It was exactly the kind of photo I wanted, but woefully small. With minimal effort and Real-ESRGAN (and perhaps a touch of artificial film grain), I blew it up to a very crisp B&W poster I framed. I'm still looking for errors in it.
I'm really looking for something fairly portable specifically for touristy street photography stuff. Perhaps it's time to pick up an X100VI...
OT: for your old Mac mini with the non-selectable Bluetooth “add” button, maybe try Mouse Keys.
