Exposure calculator Dial @
The exposure calculator dial on the back of the SB-14 helps you to select the usable range of £/stops for the speed of the film in use and the flash-to -subject distance. To set the ASA/ISO film speed, turn the dial until the number corresponding to the film speed is opposite the ASAIISO film speed index . Set the film speed to the "W" index mark @ when the Wide-Flash Adapter SW-5 CD is attached to the flash unit.
Note: Dots between the numbers on the film speed scale @represent intermediate sellings. (See illustration.)

For Automatic Operation
With the Sensor Unit SU-2 attached to the Speedlight SB-14, you can shoot on Automatic. Three usable £/stops are indicated by the thick color-coded lines after you set the ASAIISO film speed on the dial .
For example, if you are using ASAIISO 100 film, you can select either £/4, £/5 .6 or £/8. In selecting the £/stop, the flash-to-subject distance, recycling time, and depth of field are important factors.
• Flash-to-subject distance
The thick color-coded lines indicate the range of flash-to- subject distances for automatic shooting as well as the usable £/stops. Each distance range is constant regardless of the film speed set on the dial. The orange line indicates a range from 0.6m to 8m (2 to 26 ft.), the yellow from 0.6m to 5.6m (2 to 18 ft.), and the blue from 0.6m to 4m (2 to 13 ft .). So, for example, with ASAIISO 100 film and
