🏎️ Motorsports Panning Guide
Safe Start
1/250
Sharp subject, slight background blur. Good for beginners.
Sweet Spot
1/125
Nice motion blur in wheels, streaky background.
Pro Level
1/60 - 1/40
Dramatic streaks, spinning wheels. Your sweet spot!
Extreme
1/30 - 1/15
Abstract speed art. Very challenging, high reward.
🎯 Panning Technique
- • Pre-focus on the track where subject will pass
- • Start tracking before the shot
- • Smooth hip rotation, not just arms
- • Follow through after the shutter
📷 Camera Settings
- • Use Shutter Priority (Tv/S) mode
- • Continuous AF with tracking
- • High burst rate (10+ fps)
- • VR/IS set to "Active" or panning mode
⚡ Success Rate
- • 1/250: ~80% keepers
- • 1/125: ~50% keepers
- • 1/60: ~20% keepers
- • 1/30: ~5% keepers (worth it!)
How It Works
📐 Depth of Field
DOF depends on focal length, aperture, subject distance, and sensor size. Wider apertures (f/1.4) = shallower DOF. Longer lenses = shallower DOF.
🎬 Motion Blur Math
Blur = (subject speed × shutter time) / distance × sensor coverage. Panning tracks ~85% of the motion, reducing subject blur.
🔄 Circle of Confusion
The CoC defines "acceptable sharpness" based on sensor size. Smaller sensors have stricter requirements for perceived sharpness.
