With raws, you
can choose a
white balance preset
after taking the
photo, with exactly
the same results as if
you’d done so before
pressing the shutter
button. By contrast,
with JPEGs the white
balance is burnt into
the file, so it’s trickier
to tweak afterwards.
Camera Raw and
Lightroom both
offer white balance
presets at the top of
the Basic Panel that
match those found in
your camera settings.
Alongside the white balance preset
options in Camera Raw and Lightroom,
you also have the choice to set white balance
more precisely using the Temperature and
Tint sliders. If you’re editing a JPEG these
sliders simply go from +100 to -100 like any
other slider, but with raws you can adjust
the Temperature along the Kelvin scale of
color temperature from 2,000 (very cool) to
50,000 (very warm), while Tint goes from
-150 to +150.
