| Mistake | Fix | |---------|-----| | Using wide‑open aperture (f/1.8) | Stop down – but don’t go beyond f/8 equiv (diffraction) | | Focusing exactly at infinity | Back off slightly – hyperfocal is not infinity mark | | Handheld at slow shutter | Use tripod or boost ISO (but noise kills infinity detail) | | JPG compression | Always shoot RAW or high‑bitrate HEIF |
