Key ideas in Fixing Real-World Photography Mistakes
- Camera shake softens every detail across the entire frame equally
- Subject motion blurs moving elements while stationary objects stay sharp
- Inspecting unmoving background details at 100% isolates the blur's cause
- High-density sensors capture pixel-level micro-jitter that lower-res bodies hide
- The traditional 1/focal length rule fails to keep high-megapixel files crisp
- Modern high-resolution sensors require doubling the focal length for safety
- Image stabilization only compensates for the physical movement of the camera body
- Stabilization has zero effect on motion occurring within the scene itself
- Freezing moving subjects strictly requires a sufficiently fast shutter speed
- Lenses project a flat plane of focus parallel to the camera's sensor
- Tilting the camera swivels that plane along an arc, pushing it behind the target
- Razor-thin depth of field at wide apertures leaves no margin for tilt error
- Tucking elbows against the torso creates a stable skeletal tripod for the body
- Resting the lens or body against sturdy architecture cancels micro-vibrations
- White-knuckling the camera grip triggers isometric muscle tremors that cause blur
- In-camera meters calibrate overall exposure to render the scene as 18% middle gray
