Light Trail Mode Guide
Master the Light Trail mode in Iris Flow to capture stunning car light trails, fireworks, and star trails on your iPhone.
Light Trail mode is designed specifically for capturing bright streaks from moving light sources. Whether you're shooting traffic at night, fireworks celebrations, or even star trails, this mode stacks the brightest parts of each frame to create continuous, vibrant trails.
How to use Light Trail mode:
- Open Iris Flow and select Light Trail mode from the mode picker
- Find a stable position or use a tripod for best results
- Point your camera at moving light sources (cars, fireworks, stars)
- Tap the shutter and hold steady for the duration
- Watch as the trails build up in real-time on your screen
Best subjects for Light Trail mode:
- City traffic at night (capture car headlights and taillights)
- Fireworks displays
- Star trails and night sky
- Carnival rides and ferris wheels
- Any scene with moving lights
Pro tips:
- Longer exposures create longer, more dramatic trails
- Try different vantage points—overpasses work great for car trails
- The mode works best when the background is darker than the light sources
