HDR Bracketing Tips
- Use a tripod: Essential for aligning brackets
- Manual mode: Only change shutter speed, not aperture or ISO
- Remote release: Avoid camera movement between shots
- Shoot in order: Base first, then over/under exposed
- Check histogram: Ensure highlights and shadows are captured
- 2-stop spacing: Good for most scenes with moderate dynamic range
- 3-stop spacing: Better for extreme contrast (sunset, interiors with windows)
Long Exposure Tips
- Use a tripod: Essential for sharp results
- Remote release: Prevents camera shake
- Mirror lockup: Reduces vibration on DSLRs
- Focus first: Then switch to manual focus
- Check histogram: Long exposures may need adjustment
- LENR: Enable Long Exposure Noise Reduction for 30s+
- Dark frames: Shoot with lens cap on for manual noise reduction
- Spare batteries: Long exposures drain batteries quickly
