To capture a geyser eruption

[Bong Hwan Ahn]

To capture a geyser eruption with sharp water detail, high contrast against the sky, and precise timing, set up your camera before the eruption begins.

1. Exposure & Camera Settings

• Shooting Mode: Manual (M) or Shutter Priority (S / Tv).

• Shutter Speed:

  • 1/1000s to 1/2000s: Freezes fast-moving water droplets mid-air.

  • 1/2s to 2s (Optional with ND filter): Creates a silky, motion-blurred plume of water.

• Aperture: f/8 to f/11 to ensure depth of field across both the foreground vent and the top of the water plume.

• ISO: Set to Base ISO (100–200) in daylight. Increase to ISO 400–800 only if needed to maintain a fast shutter speed.

• Release Mode: Continuous High / Burst Mode. Geyser eruptions happen in seconds; continuous shooting lets you catch the peak height.

2. Focus & Framing

1. Switch to Manual Focus (MF): [안내]태그제한으로등록되지않습니다-Autofocus can lock onto rising steam instead of the water spray, leading to soft images.

2. Pre-focus: Focus on the vent ring or rocks right at the opening before the eruption begins, then lock focus.

3. Leave Overhead Space: Frame wider than expected (vertical/portrait orientation works best). Geyser plumes often shoot higher than anticipated, and room at the top prevents clipping the peak.

3. Composition & Lighting Tips

• Backlighting / Side-lighting: Position yourself so the sun hits the water spray from the side or behind. Sunlight shining through mist illuminates individual droplets.

• Polarizing Filter: Helps deepen blue skies and contrast white steam and water blasts.

• Protect Gear: Stand upwind to prevent corrosive, mineral-rich steam and spray from coating your front lens element or camera body.
