還是Raw檔看不到，轉檔或直出才出現的呢?...(恕刪)
Raw是原始檔，相機在轉檔的動作不會自動增加亮點，亮點主要是跟硬體有關。

以下是Nikon官方對於Defect (Dead or Hot) Pixels的說明。
Question
What are defect pixels?
Answer
What are defect pixels? Ocassionally images from digital cameras will have "defect" pixels. These pixels may appear in the final photograph as bright white, green or red spots that are out of place when compared to the rest of the image. Sometimes people call these spots "hot" or "dead" pixels.
Notice the green defect pixel near the center of this image.
Usually these pixels, and other types of "digital noise" appear in the darker or underexposed parts of images; additionally, images taken at longer exposure times are much more likely to have this issue.
Many Nikon cameras have a "noise reduction" or "NR" process that fixes these problem areas. When NR is activated and image exposure times drop below 1/4 of a second the NR automatically processes the images as they are saved. This Noise Reduction feature is sometimes called "Night Portrait" or "Night Landscape" Scene Modes.
If these spots are seen on images photographed under normal conditions (bright light with exposure times shorter than 1/4 second) then the camera may need to be sent in to a Nikon Service Center for repair.
=======================================================
基本上NIKON也認定有亮點是正常現像，但是在亮點的數量上並沒有明白指出到底超過多少才不正常，只說快門若1/4秒內出現亮點，建議回廠維修，這樣也太寬鬆了吧。
