Was this taken with an astrophotography mode or just night mode? I'm not sure about the S25, but with the Pixel 7 you can set the phone in a tripod and after a few seconds sitting still in night mode, astrophotography mode pops up. It takes a 4min series of long exposure shots then uses AI to combine and clean them up. You get some really impressive shots.

I used the Astrophoto mode on the Samsung Expert Raw camera app, which you can get on the Galaxy Store. 3 mins of exposure.

There's also an Astroportrait mode to take a picture of a person and then take exposure shots afterwards. Excited to try it sometime.

Ah gotcha. I wasn't sure because the tree and non sky elements look grainy. The stars look good though.

I wonder if the grain was caused by that reflective sign?

This is how they come out from my Pixel

Looks nice! And that's actually light coming from the window of our cabin. There were some dim lights outside as well, so they very well could have caused the graininess.
