Understanding Why Photos Become Blurry
Blur in photographs comes from several distinct causes, each requiring a different restoration approach. Camera shake occurs when the photographer's hands move during exposure, creating a characteristic directional smear across the entire image. Subject motion blur happens when the person being photographed moves faster than the shutter speed can freeze, resulting in a sharp background with a ghosted or streaked subject. Missed focus produces a soft, dreamy quality where detail exists but is spread across too wide an area to appear sharp. Many older photographs exhibit a combination of these issues, compounded by the limitations of consumer camera lenses and film grain. Understanding the specific type of blur is the first step in an effective restoration.
