White Balance
• Critical to “look” of the photograph
• Instructs camera computer how to
interpret colors it sees
• Set based on temperature (degrees
Kelvin) of the primary light source
• Incorrect White Balance can cause colors
that are too warm (red) or too cool (blue)
White Balance Goal
• Achieve a neutral colorcast in your photo
• Get whites to look white
• Get colors to look like what you saw when
you took the photo
