Detailed operations and various Control explained. The SB-11's tilting flash head has click-stops at 30°, 60°, 90°, and approx. 120°. For normal shooting, point the flash head straight ahead. In this position, the light travels directly out to the subject providing the maximum amount of light possible.
Tilting Flash Head
However, to soften the shadows and lower the contrast for indoor snapshots, you can tilt the flash head back to bounce the light off the ceiling or walls. Consult the illustration for details. You can also use the open-flash button ~ in conjunction with the ready light to determine if there is enough light for correct exposure before actually taking the picture.
Note: The colour temperature of the SB-11's light output is balanced for use with daylight type colour film.
Warning: Electronic flash produces a colour temperature of around 6,000 degrees Kelvin. They are generally considered to have the same photographic effect as daylight. Filters on the camera or over the flash unit can be used to alter the colour if necessary. The same applies to bounce flash - Unless the surface you are using to bounce the light off of is white or silver, your colour photographs will come out with an unnatural colour cast similar to that of the reflecting surface.
Wide-Flash Adaptor SW-3
The angle of illumination of the SB-11 by itself is 56° horizontally and 40° vertically - wide enough for use with a 35mm wideangle lens. When the Wide-Flash Adaptor is clipped onto the front of the flash head, it increases the illumination to 67° horizontally and 48° vertically providing just the right amount of coverage when a 28mm lens is used.
With the SW-3 attached, the light output of the speedlight is reduced resulting in a decrease in guide number from 36 (ASA/ISO 100 and meters) to 25. The ASA/ISO 25 and feet guide number is reduced from 60 to 42.
Note: To detach the Wide-Flash Adaptor SW-3, first rotate the tilting flash head to other than the horizontal position. Then /IR up the catch at the top of the SW3 to remove it.
Exposure Calculator Dial - For Automatic Operation
The SB- 11's exposure calculator dial helps you select the usable range of f/stops for the speed of the film in use and the flash-to-subject distance. On the dial, there are three f/stops to choose from. Each f/stop determines the usable distance range in which you can obtain the correct automatic exposure.
The automatic shooting ranges for the three f/stops are indicated by a set of curved colour-coded lines near the centre of the dial.
If the subject distance remains the same, the wider the aperture you select, the faster the recycling time of the speedlight and the greater the maximum shooting distance, but the less depth of field in the final photograph.
Conversely, if you choose a small aperture, the depth of field will be greater, but the recycling time will be longer and the maximum shooting distance is less. Therefore, in choosing an appropriate f/stop, you should take all these factors - depth of field, recycling time, and maximum shooting distance into consideration.
The following examples explain how to use the exposure calculator dial:
If you are using ASA/ISO 100 film, you can shoot subjects at distances from 0.6 -9m (2 -30ft ) at f/4.0, 0.6 - 6.4m (2— 21ft ) at f/5.6, and 0.6 -4.5m (2 -15ft ) at f/8.0.
Example 2 With ASA/ISO 100 and a subject three meters (10 feet) away, you can shoot at either f/4, f/5.6, or f/8. If a short recycling time is preferable, use f/4. If greater depth of field is desired, use f/8. Once you've selected an appropriate f/stop for the film in use and the flash-to-subject distance, set this f/number on your lens and fire away. Your pictures will come out properly exposed.
For Manual Operation: Simply read off the f/number which appears directly above the flash-to-subject distance; then set this aperture on your lens.
At ASA/ISO 100, if the subject is three meters (10 feet) away, you should set the aperture ring on your lens to f/11.
