Video Corner #15: How to Use Lighting Ratios in Photography

Lighting ratios (the difference in brightness between a key light and a fill light) can help us to be consistant in our work as photographers - the higher the ratio, the higher the contrast in our photographs. This video will discuss several common lighting ratios (1:1, 2:1, 4:1 and 8:1) and will meter the light with a Sekonic light meter.




Some points to remember:
  • 1:1 Ratio = Same output
  • 2:1 Ratio = 1 stop difference (standard portrait lighting ratio)
  • 4:1 Ratio = 2 stop difference
  • 8:1 Ratio = 3 stop difference
  • Make sure that the position of your lights are at an angle of 45 degrees or more from your camera
  • The greater the angle, the greater the contrast


The continuation of this video will be posted on the Corner Blog next Thursday (September 3rd) where we’ll discuss a couple of common lighting setups. Make sure to subscribe to the Corner Blog so you don’t miss it!
