Lightroom colour temp VS Camera Colour Temps

smithian · 27th of October 2009 (Tue)

Here's a question;

I may be mis understanding this whole process, but why does color temp in a camera get warmer as the kelvin goes down (so 5000K is warmer than 6500K), but in Lightroom you wam an image up by incerasing the number... (so 6500 is warmer than 5000).

Is the lightroom measurement not in Kelvin?

LR images seem to 'get warme'r as you raise the K value simply because its scale is indicating the color temp of the light in which the shot was made. If you made the shot in tungsten light, you lower the LR color temp to a value like 3200K in order to make the image have the correct color balance for the ambient light when the shot was made.
