Apple fixed one of my most frustrating nits with importing images from a camera card to my iPhone: those tiny thumbnails.
Tiny thumbnails on an iPhone.
In previous versions, it was difficult to tell which shots I wanted, and those I did not, because I had to make decisions based on thumbnails too small to tell.
Now, I can pinch-zoom on any of the images to unlock a bigger view to make it easier to decide which ones I want, and those that I don't.
Relief! Bigger views of my images.
This improvement has made it far more fun to bring in images from my mirrorless cameras, then incorporate them into my Photos workflow.
I'm still learning iOS 12. But at the moment, this is my favorite photo improvement.
