If you’ve noticed a difference in the range of values that appear to the right of the Temperature and Tint sliders in the Basic panel in Lightroom’s Develop module, it’s probably due to the fact that when working with Raw files, Lightroom displays values of 2000-50000 Kelvin for Temperature, and -150 – +150 for Tint. When working with JPEG, both Temperature and Tint sliders display numeric values from -100 to +100.
