Yeah, these X years ago photo memories are cool.

When I use my DSLR, I try to take a lot of photos with the intention of picking a few good ones later. These sit in storage and I usually don't see them again. As you said, it's a "zillion photos" of subject X.

When I use my phone, I generally try to take a photo here and there. But I don't need to take as many photos (vs DSLR mode).

What is a slog is when I try to take a "zillion photos" of something with my phone. It really adds noise pollution to my phone's photo album. Also, I don't like having a bunch of iPhone Burst mode photos. It really takes makes looking through my photos cumbersome and picking the "best" one to keep is a chore that nobody wants to do.
