A photo mishap is an unfortunate event that can occur when taking a photograph. It usually involves a technical issue with the camera or the lighting, resulting in a poor quality image. Two common photo mishaps are REDEYE and BLUR. REDEYE occurs when the flash of the camera reflects off the subject's eyes, giving them a red appearance. BLUR is when the image appears out of focus, usually due to a slow shutter speed or movement of the camera or subject.
