נותנים שם פירוט איך החישובים שלהם הולכים
Cameras
Point-and-shoot models: To gauge picture quality, we take a series of shots, with and without flash, at the camera's highest resolution. We photograph a complex still life, a target resolution chart, and a mannequin to see how well each camera captures details and subtle coloring such as skin tones. A panel of judges reviews on-screen and printed photos and assigns image-quality scores; we then average those scores.
Advanced models and single-lens reflex models: To gauge picture quality, we take a series of shots, with and without flash, at the camera's highest resolution. We photograph a complex still life and a mannequin using automatic settings in Program/Full-Auto Mode to see how well each camera captures subtle color and exposure under its default settings. We then photograph the same still life and a resolution moiré chart with semiautomatic settings using aperture priority, custom white balance, and exposure bracketing. We pick the best shots of each of those two subjects for judging. We also test the camera's capability for minimizing noise using a range of ISO settings. We review the on-screen and printed photos and assign image-quality scores.
The image-quality rating of the camera is based on five categories: exposure, color, sharpness, distortion, and overall.
