Congratulations on your purchase of a Sekonic DUALMASTER L-558/L-558CINE Exposure Meter
The DUALMASTER L-558/L-558CINE is the latest addition to the extensive line of Sekonic Exposure Meters, which have been market leaders for over 50 years. The DUALMASTER was designed to offer more of what todays photographer needs, and less of what they dont. It offers flash and ambient exposure metering in both spot and incident modes. The DUALMASTER is the first multi-function meter to offer a 1-degree (nine element camera-quality) spot that measures reflected flash output as low as f/2.0. Along with its many unique features, the L558 is also capable of wireless flash triggering with an optional radio module. Utilizing rubber seals throughout the housing and controls of the meter, the DualMaster is water and moisture resistant. Although the meter can be used in rainy or wet conditions, it should not be used underwater. The large LCD panel makes reading the data easy and convenient; the panel illuminates automatically in low light surroundings. In order to retain the simple stylish look of the DUALMASTER, less frequently used functions and controls are confined to custom software settings. The DUALMASTER L-558 and L-558CINE is loaded with many features and control options. Since each of these features has a detailed explanation, this instruction booklet is extensive. We recommend that you read the manual to familiarize yourself with the potential of the meter. Once you have established which features and functions are important to you, refer to these sections only. The DUALMASTER has undergone extensive quality control at every step of manufacture. Please read this instruction manual thoroughly, to be able to take advantage of its many features and to obtain the long service life that it was designed to offer you. Thank you for investing in Sekonic.

Reference: L-558 CINE can read Cd/m2 or FL directly when the custom setting function is used (refer to page 32).
6. How to use the Exposure compensation function Exposure compensation can be made in precise 1/10 step increments in a +/- 9.9 EV range. Exposure compensation may be desired when requiring compensation for filters, bellows extension, etc.
Making a plus compensation will result in underexposing when taking a photograph. Hold the ISO1 button !1 and the ISO 2 button y and turn the Jog wheel t counter clockwise. The will appear on the upper right part of the LCD. The compensation will change in +0.1 EV steps up to +9.9.
Making a minus compensation will result in overexposing when taking a photograph, Hold the ISO1 button and the ISO 2 button and turn the Jog wheel clockwise. The will appear on the upper right part of the LCD. The compensation will change in -0.1 EV steps up to 9.9.
NOTE: Make compensation after a sufficient number of tests in actual photographic conditions have been made to suit your needs. Compensation effects every mode of the meter. If recalibration has been made for specific purpose do not forget to return to original zero settings.
Reference: When compensation is activate, a plus ( ) or minus ( ) sign as well as the amount of compensation is displayed continuously on the LCD display. You can set custom settings so that a plus ( ) or minus ( ) sign as well as the amount of compensation doesnt appear on the LCD. (See page 32)
7. How to use Calibration compensation function Calibration compensation can be made in precise 1/10 step increments in a +/- 1.0 EV. It may be desired to match specific requirements, calibration to other meters, etc. 1. Set the measurement mode (incident light, reflected light) for the desired compensation. You can make calibration compensation independently for both incident, and reflected light. It is not possible to switch between measurement modes if the setting is not completed. To enter the calibration setting of the meter it must first be turned off. Press the power button on while holding down the ISO1 and ISO2 buttons simultaneously ; the screen will display CAL 0.0 (for calibration). The calibration setting can be changed by rotating the Jog wheel while pressing and holding down the ISO 1 and ISO 2 buttons simultaneously. A range of +/- 1.0 EV in 1/10 step increments is possible for calibration.

NOTE: When making calibration compensation, be sure that it satisfies your needs based on the results of adequate test film. While incident and reflected light can be set independently, be aware that both ambient light and flash exposure are corrected uniformly.
Reference: The calibration setting is not displayed on the main screen once it is set.
8. Filter compensation Filter compensation (1) It is possible to compensate for filter factory within a range of 5.0 EV in 1/10 steps. The measurement corresponding to the set compensation is displayed while pressing ISO2 button y. 1. 2. Select setting number 1 and item number 1 in the custom setting mode (refer to P32).

(Filter factor numbers are Kodak Wratten filter numbers.)
9. Flash analyzing function When measuring flash light, the shutter speed and F stop value (value combining ambient light and flash light: total amount of light) are displayed in the liquid crystal display and the ambient light and flash light are each displayed as separate values together with the total amount of light on the analog scale. In addition, the ratio of flash light to the total amount of light is displayed at that time as a value in 10% steps. It is possible to use this value for adjustments, for example, when photographing with a flash in a room illuminated by tungsten light, to emphasize or weaken the tungsten (ambient) light element (enhancing the flash light of the photograph) to match the photographer's intentions. < Example > If, under certain conditions, the flash light component is 60% and the tungsten output component is 40%, the display will be as indicated at the right. Flash reading on the analog scale will blink.

Perecentage of flash in total exposure
To emphasize the tungsten (ambient) light (to imbue the atmosphere with orange-colored tones) To increase the ratio of tungsten light, use the Jog wheel t to change the shutter speed to a slower setting. It is apparent that the flash light component is now 20%. The analog scale also shows the tungsten output component to be about 2.5 stops higher than the flash light component. As a result, images on the film are expressed with orange tones that give life to the effect of the tungsten light.

Ambient

Measured f stop (total exposure)
To reduce the effect of tungsten light (to realize a more natural atmosphere) To decrease the ratio of tungsten light, use the Jog wheel to change the shutter speed to a faster setting. It is apparent that the flash light component is now 80%. The analog scale also shows the flash light component to be about 1.5 stops higher than the ambient light component. As a result, the images on the film are expressed in natural color tones.
Reference: Slower shutter speeds allow more available light to reach the film, and faster shutter speeds allow less available light to reach the film. The settings above are made by adjusting the tungsten (ambient) light by the shutter speed. It is also possible to modify the ratio by adjusting the flash light (when changing the distance between the flash and the subject or when changing the amount of light of the flash). When using this method, re-measure each time the flash light is adjusted. -31-

In sub-channel settings, after the channel is set to 17 to 32, the assigned buttons below are pressed. Pressing each of the buttons activates or deactivates the sub-channels (A, b, c or d). When a sub-channel is activated, the corresponding sub-channel letter appears on the display. If a sub-channel is deactivated, a - is displayed in place of the letters.
Each assigned button enables to set

sub-channel directly.

When using quad channels 17-32, it is not possible to terminate this mode unless a subchannel has been set (A, b, c or d is displayed). -35-
6. Upon setting the channel and sub-channels, press Measuring button !4 to set radio triggering mode automatically, or the Wireless flash radio triggering mode or Wireless multiple flash radio triggering mode is selected using the Jog wheel while the Mode set button is pressed. For other settings of the measurement, see page 17. Confirm that the meter and the radio receiver are set to the same channel number. The flash unit will fire when the measurement button of the meter is pressed and measurements can be made at the same time.
Reference: Refer to the receiver instruction manual for the receiver operating method. Maximum controllable distance of the radio flash trigger system differs depending on the placement of the device, direction and other factors. 1. Confirm the direct visible range between the transmitter and receiver. 2. Place the meter and receiver away from large metal objects, concrete, objects with large moisture content (both people and trees fall into the category) and so forth. 3. Secure the radio receiver in place by using Velcro tape or mounting 1/4-20 thread. Be sure that the entire length of the receiver antenna is higher than the flash pack at this time. Avoid contact between the receiver antenna and metal objects at all times. 4. Depending on the location, there may be cases when the receiver is incapable of receiving any radio signals whatsoever. There are various possible reasons for this such as radio signals reflected from nearby objects. This can generally be resolved by shifting the device slightly in one direction or another. In addition, confirm that the device is not placed behind objects that readily absorb or deflect radio signals such concrete, metal, low hills, etc.
