What this page is: a quick, visual step-by-step guide for Expert RAW and Pro mode, including no-tripod setup.

You’ll need (keep it simple)

・Galaxy phone that supports Expert RAW

・A dark location (the darker, the better)

・A stable surface (wall / rock /car roof)

・Optional: tripod

1) Expert RAW (Astrophotography) — the easiest option

Step 1 Open Expert RAW

Open Camera → More → Expert RAW

If it isn’t installed yet: tap Expert RAW and follow the on-screen prompts to download it. You can also download Expert RAW from the Galaxy Store.

Step 2 If you don’t have a tripod: turn on a timer

Tap the Settings icon (looks like four dots in a circle on many models).

Turn on Timer → set to 10s.

Step 3 Save RAW + JPEG

Tap RAW / JPEG → choose RAW + JPEG

Then close settings (✕) to return.

Step 4 Enable Astrophotography mode

Tap the Labs icon (flask) → Astrophotography → ON

Step 5 Capture time: choose “Short”

Set Capture time to Short

(Long often doesn’t look dramatically better, and takes longer.)

Then close settings (✕) to return.

Step 6 Frame and shoot

Choose your lens / framing → press the shutter.

No tripod tip: after tapping shutter, place the phone firmly against a wall or on a stable support within the 10s timer.

Quick edit (built-in Gallery)

Open Gallery → Albums → Expert RAW → pick the photo

Tap Edit (pencil)

Adjust (light touch): Contrast / Highlights / Shadows

Save as a copy (Save copy)

2) Pro Mode — still great (often enough)

Shot on Galaxy S25 Ultra (Pro mode)

Step 1 Open Pro mode

Camera → More → Pro

Step 2 No tripod: timer again

Tap the Settings icon (four dots in a circle) → Timer → 10s → close (✕)

Step 3 Set ISO + Shutter speed

Set your framing first, then adjust ISO and Shutter.

Important: Many guides say “ISO high + 30s shutter,” but on phones this can easily look worse. For details, see this link: [Galaxy Astrophotography: ISO 400 vs 1600 for Stars & the Milky Way (Why I Don’t Expose by the Viewfinder)]
