Resumen del manual
Press the diffuser until it clicks into place. . Notes on using the diffuser . If the arm is set at the 60° position and used with a wide angle lens, the diffuser may appear in the image. It is recommended that you always use the diffuser with the arm set at the 90° position. . The flash output is reduced when using the diffuser. See page 28 for TTL flash metering, or page 38 for manual flash metering. Removing the diffuser 1 Remove the diffuser while holding its panel’s top tab. 2 Pull the tab off the dimple as illustration. The diffuser can now be easily removed. 3 Refold the diffuser and secure it by clipping the panel to it. Detailed Custom setting The various flash settings can be changed as necessary. The following three items may be changed. . Time to auto power off (4 minutes/15 minutes/60 minutes/None) . Recording modes in which manual flash may be set (M mode only/All modes) . Manual-flash power-level steps (1EV increments / 1/2EV increments) 1 Press the flash ON/OFF button for three seconds. The auto lamp, flash-ON lamp and flash-OFF lamp all come on together, and the item (time to auto power off ) is displayed. 2 Press the A-B button (twin-flash A-B selection button) to select the item, and press the TTL/M/Test button to select the desired setting. Each time the A-B button is pressed, the above three items appear on the control panel (see following page).

When a setting other than the default setting is selected in custom mode, the custom lamp on the control panel comes on. . When “All modes” is selected (see 2. Recording modes in which manual flash may be set), manual flash may be used in all recording modes.* * The proper exposure may not be obtained in modes other than M mode. Using M mode is therefore recommended. . If “1/2 EV steps” is selected in item 3, use the gray power values provided on the lower scale of the manual-flash-control dials. The half-stop values are not written on the scale. The power values are1/1, 1/1.4, 1/2, 1/2.8, 1/4, 1/5.6, and 1/8. . The selected settings are maintained even when the flash unit is turned off or the battery removed. 0 Examples of macro twin flash photography By using this macro twin flash, you can change the position and angle of the twin flash unit to achieve more expressive lighting. Example: Top light only Side light only Top and side light Strong shadows of the subjects can be softened by using the diffuser attached to the flashtube (p. 44). Example: Top light with diffuser Additional Continuedonthenextpage 1 Two twin flash shooting with arms To accent detail and give depth, illuminate the subject from the sides using the arms. Example: With arms from the sides Without arms from the front Note If a close-up subject is illuminated from the side using an arm, strong shadows may occur. Strong flash illumination from behind the subject can cause flaring. . This condition is particularly likely to occur with a 50mm F2.8 Macro lens with flashtubes mounted on arms. Example: With arms from the sides Without arms from the front Additional Aperture range graph The aperture range for macro lenses is displayed on page 26 (TTL), and page 34 (Manual flash). The aperture ranges described here are for lenses other than macro lenses, or when the subject distance is large. TTL flash metering Flash-subjectMin.AperturelinesAperture Max.AperturelinesMin.AperturelinesMax.Aperturelines distance The following explains how to obtain the aperture range using the two twin flash units with a 1.5 m flash-to-subject distance and at ISO 100. 1 Draw a vertical line upwards from the flash-to-subject distance until it reaches the minimum aperture line (.). 2 Draw a horizontal line leftwards from .until it reaches the vertical ISO line corresponding to the camera used (.). 3 Draw a diagonal line from .upwards and leftwards. The result indicates the minimum aperture that will provide the proper exposure (.). 4 The maximum aperture can be obtained in the same way by using the maximum aperture line (.).The results of both calculations will give the usable aperture range for obtaining the proper exposure (.). In this case, the proper exposure can be obtained by setting the camera’s aperture from maximum to f/16. . The dotted lines are employed when only one twin flash unit is used.
