Colour temperature

Go to solution Solved by LaFemmeEnVert,

in the camera when you manual change color temperature for white balance you are changing to compensate for the color temperature of scene you film or photograph so if there is a object that is white in color in the scene the camera sees it as white color and not other color.  so if the light shine on the white object is blue light (cold) you need to tell teh camera that the camera the artificial light on the object has blue color and compensate so that the camera sees the white object as white or if light is red (warm) is the same concept.  this is why you think the info of color temperature you find on google and what you see in camera is opposite.

 

if you photograph in a room with painted white walls and has incandescent light bulb lamps which to our eye look yellow and in the camera you set white balance kelvin to low number like 3000 when you look at the photo you take the colors of the room walls appear white because you are telling the camera that it is taking photo of place where the ambiant light is warm.  but if you change kelvin to 10000 for the same room with the same lights the photo looks super orange it happens because you make the camera think the lighting of the room is cold so the camera compensates (with error) to compensate for the light to get correct color of the wall.

What the F ! is going on ?!

So I just randomly got into googling colour temperature and what I found is opposite of what I experience when I take photos with Canon 70D or use lightroom. Both of which follow my common sense "low number (2000K) = cold/blue, high number (6000K) = hot/red".

But for some reason if u put "Kelvin scale" in google images all the charts suggest the opposite "high number = blue, low number = red". 

Why is that a thing ? Is this different depending on a country ? What am I missing here ?
Someone please help this is driving me mad !

Examples:

No.1 (WTF?!)

No. 2 (This is what I expect)

No.3 (WTF again!)

the higher k value are thought as cool and lower k value as warm for the color it emits or radiats and not real temperature.  if you heat a piece of metal, at low temperature the color of the heated metal looks yellow or red or orange like but if it is heated more to be hotter and hotter the color looks more blue to white.  read the wikipedia page for color temperature for better explanation

yeah what would i know about cameras or cinematography compared to you tech people.  i've only done this work for nearly 20 years, won a few awards, worked in over a dozen different countries and a few multi million dollar projects
