How to capture a Geyser Eruption using iPhone Burst Mode

Stroker Geyser was one of the highlights of my Iceland road trip. It's located approx. one hour by car from Reykjavik in a geothermal zone. The Geyser erupts every 5-10 minutes and sometimes even twice within a few seconds. I was lucky to witness such an impressive "serial eruption".

Capturing a geyser eruption, especially during its early stage, requires either a very good reaction time or a new iPhone model with "burst mode". With burst mode, the iPhone takes 100s of photos within a few seconds. The official specification mentions about 10 fps (frames/shots per second), but I felt it's way faster. I captured more than a 100 shots in burst mode during an eruption that lasted only for a few seconds.

To shot in burst mode with the native iPhone camera app, tap and hold the shutter release button on the camera app or the "+" volume button. The iPhone camera app will take a single photo and then switch into burst mode within a second and will shoot until you release the shutter release button.

To avoid camera movement and blurry photos when shooting in burst mode and while keeping the shutter release pressed, I put the iPhone on a tripod and used a remote shutter. The volume "+" key on your headphone will work well as a remote shutter. I prefer to use Muku Shuttr, a bluetooth wireless remote shutter, that's ready to use within a second (no untangling of the cables from your headphone!)

When you're done shooting, go to the camera roll and tap the photo stack you just shot. Tap "select" and chose which photos you want to keep from the burst shots. Swipe left and right to move between all shots. Finally you can choose if you want to keep all burst shots or just the ones you selected and discard the others.

Hint: Before the geyser erupts, you will see the water getting hotter, creating some bubbles and it will slightly pulsate before it erupts.
