問：照片出現重疊情況 或 只有半格相。THE PROBLEM: Photo overlapping and/or photo missing in half.答：有機會不小心按到回片制或重曝制令畫面重疊，如半格通常發生在重疊相後，因為畫面不是原整一張，所以只有半格相。WHY: Some cameras has a double-exposure button which allows the same frame to be exposed more than once. While overlapping photos can be caused by inappropriate/accidental use of the double-exposure button, it can also be caused by advancing a frame while the camera is in rewind position. Furthermore, since the next frame is now overlapped with the previous frame, the next frame will only have less than full to half proportion left to be scanned.
