I use Cloudflare tunnel to make it available outside the home network. I've set up two DNS names – one for accessing it directly in the local network, and and a second one that goes through the tunnel. The Immich mobile app supports internal/external connection settings – it uses the direct connection when connected to home wifi, and the tunnel when out and about.
For uploading photos taken with a camera I either use immich-go (https://github.com/simulot/immich-go) or upload them through the web UI. There's a "publish to Immich" plugin for Adobe Lightroom which was handy, but I've moved away from using Lightroom.
I love the immich success story but it seems like it's missing a crucial use case in my view: I don't actually want a majority of the photos on my phone. I want something like a shared album that me and my wife both have access to, and so we can share photos specifically to that album (quickly and without hassle), so we can do it in the moment and both have access.
I would probably estimate 90% Of my photos are junk, But I want to isolate and share the 10% that are really special.
My app failed, but I'm thinking about reviving it as an alternative front-end to immich, to build upon that.. But I feel like I'm the only one who wants this. Everyone else seems fine with bulk photo backup for everything.
Immich put the joy back in photography for me, it's so easy to find anything, even with just searching with natural language.
Being able to scroll to dates with immich is golden. And the facial recognition is on device and works great.
I actually did the math earlier and the iCloud 12TB plan for a family is way cheaper than the equivalent s3 storage assuming frequent access, even assuming a 50% discount. so that's nice.
FWIW, I also don't use any fancy collection management and barely understand what all these Lightrooms and XMP files are for. Maybe I should, but up to this day photos for me are just a bunch of files in the folder, that I sometimes manually group into subfolders like 2025-09, mostly to make it easier on thumbnail-maker.
