Guide Numbers for Determining the Correct Aperture

Guide numbers help you determine a correct exposure or proper aperture (f/stop) when

using the SB-28D Speedlight in the Manual or Repeating Flash mode.

The guide number represents the amount of light at ISO 200 for meters/feet (m/ft)

generated by the flash. With the SB-28D Speedlight, you can calculate a correct aperture

or desired flash shooting distance by using the following equations and the guide number

table.
