The units of measurements displayed in the Basic panel (in Lightroom’s Develop module and in the Camera Raw dialog in Photoshop) for Temperature and Tint differ between RAW and JPEG files. When working with a raw file, the Temperature slider ranges from 2,000 to 50,000 Kelvin and the Tint sliders range from -150 to 150. When working with JPEG files (or other pixel based files such as PSD or TIFF) the Temperature and Tint sliders both range from -100 to 100.
You might also notice that when working with RAW files, Lightroom displays a list of “preset” White Balance settings (Auto, Daylight, Cloudy, Tungsten etc. – this list might differ slightly from camera to camera). When you work with a JPEG file, LIghtroom only displays As Shot, Auto and Custom in the pull-down menu

Kelvin did not use the term “degree”
Thanks!
Hi Julieanne, for shooting RAW I understand that I can do white balance changes in Lr without loss of quality. But still one or the other white balance setting in the camera might be preferable in order to have less effort in Lr. Is there a recommendation you could let us know?
Hi Julieanne,
I have just made the switch over to shooting in RAW (reluctantly). I am still learning. I am having trouble with the new temperature scale of 2,000 to 50,000 compared to the 100 scale when shooting in JPEG which I found to be so much easier. Moving the scale up like I used to in order to warm up an image is not having the same effect. It is not making my images far to orange and yellow. Any idea how to achieve the same effects I was getting before?
