White Balance

The task today was to shoot inside a large building at a variety of stations with different  blends of lighting conditions and take identically framed shots with different white balances. Being 1) Auto: 2) Daylight: 3) Custom (using white card): 4) Custom (using expo disc)
 5) :Custom using a colour meter reading;

As my camera was unable to manually dial in a colour temp from the colour meter reading, I had to forego that pleasure

These are the results

We then got moved on from this station so were unable to complete the task here

Clearly there are many ways to achieve a better/correct white balance, but custom white balance that uses the key light seems to render a more accurate result.
