hi

clear my doubt


3200 clour temp is warm(tungstun)

5600 color temp is day light


But in alexa if u need warm(means more warm) temp you have to 9100 why(Generally 2700 gives more warm than 3200)


what is this confusion?

Because if the light is 3200K but you set the camera to 3700K, for example, then the camera will be balanced so that 3700K is "white" and thus 3200K would look warmer in comparison.

If the light was 3200K but you set the camera to 2700K, then you are telling the camera that 2700K is "white" and thus 3200K will look cooler in comparison.

You have settings above 5600K so that daylight can be rendered warmer. If the camera is set so that 7000K is "white" then 5600K light is going to look warmer in comparison.

You sure your light is balanced to 3200k? By the sounds of it you have a 5600k light, thats the only reason it could be blue when you dip below 5600k and warmer when over it.
