Definition
Light ratios measure the intensity difference between the main light source and secondary lighting in a scene. They are typically expressed numerically, such as 2:1, 4:1, or 8:1, indicating how much brighter one light is than another.
Visual Impact
Low ratios produce soft, evenly lit images with minimal contrast, while high ratios create dramatic shadows and strong tonal separation. The ratio chosen directly affects emotional tone and realism.
Practical Use
Portrait photographers and cinematographers adjust light ratios to control mood, from bright commercial looks to cinematic dramatic lighting.
Professional Insight
Understanding ratios allows precise lighting replication across shoots and scenes.
