Portrait FOV = 2×arctan(24/(2×35)) = 37.8°. Effective = 37.8×0.7 = 26.5°. Shots = ceil(180/26.5) = 7. Rounded up with margin: 9.

Portrait FOV = 2×arctan(24/(2×50)) = 27°. Effective = 18.9°. Shots per row = ceil(360/18.9) = 20. Total = 20×2 = 40 shots.

Frequently Asked Questions

Q

How many photos do I need for a panorama?

Depends on focal length, overlap, and total angle. A 180° pano with 35mm lens (portrait) at 30% overlap: about 9 shots. With 50mm: about 13 shots. Use portrait orientation for taller coverage per row.

  • Wider lens = fewer shots needed
  • Portrait orientation = more vertical coverage
  • 25-35% overlap is standard
  • More overlap = easier stitching but more shots
  • 360° doubles the shot count vs 180°

Q

What overlap percentage should I use?

25-35% is standard for most stitching software. Less than 20% may cause stitching failures. 40-50% is safer for complex scenes (moving water, crowds). More overlap = larger final file.

  • 20% minimum for basic stitching
  • 30% standard and reliable
  • 40-50% for complex/moving scenes
  • Lightroom/Photoshop handle 25%+ well
  • PTGui works well even at 20%
Q

Should I shoot panoramas in portrait or landscape?

Portrait orientation is usually better. It gives more vertical coverage per row, resulting in a taller final image. The trade-off is more shots needed. For a single row, portrait captures more sky and foreground.

  • Portrait: more vertical coverage per row
  • Portrait: taller final panorama
  • Landscape: fewer shots but shorter vertically
  • Portrait: better for single-row panos
  • Multi-row: landscape OK with more rows
Q

How large is the final panorama file?

Multiply your camera resolution by the effective number of non-overlapping shots. A 24MP camera with 9 shots at 30% overlap: ~24 × (9×0.7) = 151 MP. Final TIFF can be 500MB-2GB.

  • Final MP = camera MP × shots × (1 - overlap)
  • 24MP × 9 shots × 0.7 = ~151 MP
  • TIFF at 16-bit: ~1 GB for 150 MP
  • JPEG output: 50-150 MB
  • Larger files need more RAM to stitch
