你是指autoexposure?
建議你用手動模式
full manual control of shutter speed, aperture and exposure compensation is possible when shooting video but there are some restrictions. You can only take manual exposure control in the A77's dedicated movie exposure mode (found on the main exposure mode dial), and this is incompatible with AF
去menu裡進入dedicated movie exposure mode,可是就沒有自動對焦了
你要知道,在auto-exposure的模式下,相機會以進來的光來考量曝光... 當相機看到白色的襯衫,就會以白色來做18% grey,白色比18%灰還亮,所以相機就會把它調暗,相對的,黑色就會調亮,所以你才會有這個問題.
在拍攝影片時,請用手動模式比較理想
