Shooting under dim LED lighting now common in small performance venues can be challenging to put it mildly. What often happens is that most of the light is from only a narrow part of the visible spectrum and either the blue or red channel will blow out completely. This is especially true when green is totally absent. If you are looking at a brightness ...

I did consider the possibility that your extreme red/violet lighting might have been affecting your autofocus accuracy. i.e. the camera's AF system focuses the lens at 3.000 meters without taking into account the fact that the lens may not be calibrated for deep red light focus and 3.000 meters is really 3.004 meters under red light and is therefore slightly ...

cajunc2's answer explains what has gone wrong. But you can try to correct the problem using the program DCRaw. You can use this program to convert the raw file to a tiff file where no interpolation (demosaicing) is done. The overexposed pixels will have caused blooming (i.e. overflow of electrons to the neigboring pixels), you can measure this effect using ...

The general fuzziness and lack of detail in these photos is mostly due to being lit primarily by one strong color. Your camera's sensor has what is called a Bayer color filter array on it which allows it to record only one primary color per sensor element. In your camera or raw processing software, the single-color-per-pixel sensor data is combined to ...

Ok, I see the problem you're talking about - but only just. My first impression is that the diagnosis from Nikon is quite plausible. My second thought is that the reason you don't see the artefact in still is because it possibly only is visible if you drastically underexpose the shot like you did in the video. Try taking a correctly exposed shot of a pale ...
