Congratulations on your purchase of a Sekonic Flash Master L-358 Exposure Meter.
This meter provides a wide range of functions that correspond with most manufacturers camera settings in all formats, which will satisfy professionals as well as serious enthusiasts. Its sealed housing and controls make it water and moisture resistant. Yes, you can use it in the rain, but it is not an underwater meter. Its large LCD display makes readings easy and lights up automatically in dark surroundings. In order not to crowd the controls, four functions which are less frequently used, are confined to DIP switches, located in the battery compartment. Because of its many features, the L-358 requires this rather extensive manual. But since you will never use them all at the same time, once you have learned all about it, it is simple and its use will become second nature. The Flash Master L-358 has undergone extensive quality controls 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 it is designed for. Thank you for your confidence in Sekonic.

Lumisphere 2.

Retracted Lumisphere
When the Lumisphere is raised This is used to photograph people, buildings, and other three dimensional objects. Measurements are basically made by the method of measuring with the lumisphere aimed in the camera direction (more precisely, in the direction of the light axis of the lens) at the position of the subject. When the Lumisphere is lowered (flat diffuser function) This is used to photograph manuscripts, paintings or other flat copy. It can also be used for measuring illumination levels (see page 25), or brightness difference (see page 23).
NOTE: If the device is used with the Lumisphere retracting ring in a middle position, distributed light quality will change, and suitable measurements cannot be made. Do not push the Lumisphere down manually. If the lumisphere becomes soiled, wipe it with a soft, dry cloth. Organic solutions (paint thinner, benzene, etc.) must not be used under any circumstances.
When set for incident light 1. Incident light measurements can be performed with the lumisphere fully extended or in the retracted position. You can switch between Lumisphere in the up position or retracted position by firmly rotating the Lumisphere retracting ring q until it clicks.
4. When set for reflected light This method measures the brightness (luminance) of the light reflected from the subject. It is useful for distant objects such as landscapes, when you cannot go to the position of the subject, or for metering subjects that generate light (neon signs, etc.), highly reflective surfaces or translucent subjects (stained glass, etc.). < Using the lumigrid > (Receiving Angle 54) 1. Remove the Lumisphere The lumisphere unit is removed by holding both the upper and lower sections of Lumisphere retracting ring q and turning it counterclockwise while pushing the Lock lever !4 downward.
Mount the lumigrid To mount Lumigrid @ 3 , align the mount/removal indicator on the Lumigrid with the mark and, while pressing it, turn it in the clockwise direction and secure it in place by raising the Lock lever until it clicks into place.

3. The shutter angle that these speeds are based on, is 180 degrees. For other angles make the following ISO film speed corrections. Shutter open angle 160 degrees 220 degrees Amount of ISO film speed correction -1/3 +1/3
* Example of correction value -1/3: Decrease ISO film speed by 1/3 stop, example: ISO 100 -1/3 stop = ISO 80 +1/3: Increase ISO film speed by 1/3 stop, example: ISO 100 +1/3 stop = ISO 125 4. Press the Measuring button ! 5 to make a measurement. Release the Measuring button to complete the measurement. The measured value (f stop value) will be displayed. While pressing the measuring button, the meter measures continuously until it is released.

2. Measuring flash light This method of measurement can be done in the following modes; with cord, without cord, multiple flash with cord, multiple flash without cord and Wireless flash radio triggering mode (with optional radio transmitter module). When Measuring flash light, the shutter speed and F stop value (value combining ambient light and flash light: total amount of light) are displayed.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.The flash reading is displayed as a blinking mark above the analog scale.(See page 27 for details) 2-1 Cord Flash mode The most positive method to assure proper synchronization and measurement of flash units. Connect the meter to the flash with a synchronization cord. Be sure to replace Synchro terminal cap @0 after your measurement. 1. Connect the flash synchro cord to the Synchro terminal i on the exposure meter.

There is danger of electric shock if the meter is handled with wet hands, during rain, in areas splashed by water or where there is a lot of moisture, if you use cord synchronized flash. Under such conditions, it is recommended that you use the meter in the cordless flash mode or wireless flash radio triggering mode, and keep the Synchro terminal cap in place. NOTE: The electronic flash unit may fire when you connect the Synchro cord or operate the POWER Switch. For flash units with extremely low electric trigger voltage, the flash may not fire. In this case, make measurements in the cordless flash mode or wireless flash radio triggering mode. Reference: It is possible to switch between full, 1/2 and 1/3 shutter speed stop by setting DIP switch 3 and 4. The shutter speed can be set from 30 minutes to 1/1000 of a second. After 1/1000 sec, the meter can be set at the following intermediate speeds: 1/75, 1/80, 1/90, 1/100, 1/200, or 1/400. If the film speed is changed after the measurement is taken, the new converted measured value (f stop value) will be displayed. After measurement, the F stop value corresponding to the shutter speed is displayed when the shutter speed is changed. E.u (Exposure under) or E.o (Exposure over) appears when the combination of shutter speed and aperture are outside the display range. Change the shutter speed with the Jog wheel and take measurements again. If the E.u or E.o readout blinks, this indicates that the light level is beyond the measurement range of the light meter. 2-2 Auto-reset cordless flash mode Measurements are made by the meter receiving the light from the flash. This measurement mode is used when the Synchro cord will not reach because of the distance between the flash and meter or when use of the Synchro cord is inconvenient. 1. Hold down the Mode set button !0 and turn the Jog wheel t to set Auto-reset Cordless Flash. mode

2. Turn the Jog wheel to set shutter speed. When setting shutter speed, first check the settings to confirm that they correspond to the settings available on the camera.

3. When the Measuring button !5 is pressed, the mode mark will blink and the meter is ready to measure. The ready to measure mode will continue for approximately 90 seconds. During this time, fire the flash and make a measurement.
4. If the 90 second period is exceeded and the blinking mark stops, press the Measuring button again to return to ready to measure.
5. When the light from the flash is received, the measured value (f stop) is displayed. Even after continues to blink measurement, the mode mark and the meter is in ready state and new measurement can be made. (Auto-reset function)
NOTES: When firing a flash, if the flash brightness is 9EV lower than the ambient light, the meter may fail to detect the light. In this case, make measurements using the Cord flash mode. Rapid start fluorescent lamps and special lighting are sometimes mistaken for flash, and accidentally measured. In this case, make measurements using the Cord flash mode.
Reference: After measurement, the F stop value corresponding to the shutter speed is displayed when the shutter speed is changed. Setting the shutter speed is similar to the previous instruction (see page 15) of "Cord flash mode" of section 2-1. A new converted value is displayed when the film speed is changed after taking the measurement. Readings outside the display range or beyond the measuring range are similar to the previous instruction (see page 16) of "Cord Flash mode" of section 2-1.
2-3 Cord multiple flash (cumulative) mode These measurements are used when the light generated by the flash is inadequate for proper exposure. The repeated flash pops can be accumulated until the desired aperture is displayed. The cumulative number is infinite. Only one digit is displayed if the cumulative number is ten or more.Display returns 0 (0=10, 1=11, 2=12 etc.) 1. Slide DIP switch 2 to MULTI (see page 8) to the ON position. Hold down the Mode set button !0 and turn the Jog wheel t to select cord multiple flash (cumu. lative) mode

How to change Calibration compensation Calibration compensation may be desired to match specific requirements or calibration to other light meters. 1. To enter the calibration setting of the meter it must first be turned off. Press the power button on while holding down the ISO 1 and ISO 2 buttons simultaneously; the screen will display CAL 0.0 (for calibration). 2. The calibration setting can be changed by rotating the Jog Wheel while pressing and holding down the ISO 1 and ISO 2 button simultaneously. A range of 1.0 EV in 1/10 stop increments is possible for calibration. The calibration setting is not displayed on the main screen once it is set.
NOTE: Make compensation after a sufficient number of test in actual photographic conditions, 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. doesnt appear In Exposure compensation the always appear on the LCD,while the in Calibration compensation. -26-
6. Flash analyzing measurement 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 lamp light, to emphasize or weaken the tungsten lamp (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 light component is 40%, the display will be as indicated at the right. Flash reading on the analog scale is blinking.
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 light component to be about 2.5 stop 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.
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 stop higher than the ambient light component. As a result, the images on the film are expressed in natural color tones.
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. -27-
7. Wireless flash radio triggering function With the radio transmitter module plugged into the meters radio compartment and a receiver (RR-32 or RR-4 sold separately) connected to one or more electronic flash units, the meter provides a convenient system that enables one person working alone to measure flash output without the need of a sync cord. Pressing the measuring button simultaneously triggers the flash and measures the light. The L-358 has 32 triggering channels when the radio-triggering module (RT-32) is plugged into the radio compartment. Channels 1-16 provide single triggering, while channels 17-32 offer Selective Quad-Triggering capability.Selecting one of channels (17-32) provides control of up to four additional sub-channels (A, B, C, and D). Selecting or deselecting of zone lighting is possible with sub-channels. In order to trigger flash units set for sub-channels, the electronic flash unit must be connected to an RR-32 receiver (sold separately). With an RR-4 receivers (sold separately) triggering channels 1-4 can be selected.
RT-32 radio transmitter module
< Example with optional radio receiver RR-32 > 1. Open battery cover !, remove connector cover @and set the radio transmitter module (optional) by aligning the connector with the pins.

CAUTION

To prevent damage due to static electricity, release static electricity stored in your body by touching a metal object nearby (door knob, aluminum window frame, etc.) before touching the radio transmitter module.

NOTE: The radio flash system may be used only in countries where a permit for the control frequency has been issued by the govenment office in charge.

Sekonic Flash Master L-358
The simple solution to creative light control with optional wireless triggering Directional light is powerful. It guides the viewer, creates mood, and adds dimension, depth, and texture. If you want to create a signature style that elevates your photography to the next level, the mastery of off-camera lighting should be your next goal. Subjects clients are not impressed with a shoot, view, and adjust photo style. Lighting ratios, ambient balance, and final exposure must be set confidently. Knowledge and use of the tools of photography assure that the outcome is the intended one. And for images like this one, the Sekonic L-358 is the professional photographers meter of choice.
Incident Light Metering Unlike in-camera metering, handheld, incident light meters dont require multi-patterned readings, complex exposure control systems, or +/- exposure correction when they fail. They are, in fact, the simplest and most direct way to determine exposure. And because incident meters measure the light that falls on your subject, they provide camera settings that render the image exactly the way it appears. Blacks are black. Grays are gray. Whites are white. Retracting the Sekonic L-358s Lumisphere enables you to quickly judge the brightness of multiple light sources for fast, accurate adjustment of lighting ratios.
Take exposure measurements of three-dimensional subjects with the Lumisphere extended.
Retract the Lumisphere to read single sources or exposure readings for flat subjects like art work
3 Sekonic Flash Master L-358
Ambient Light Metering Take shutter-priority or aperture-priority readings from 30 minutes up to second and f/1 to f/90.9 with -stop accuracy. The L-358 displays exposure both digitally and on an analog scale for easy readout. Custom functions enable adjusting the shutter speed and aperture readout for full, half, and third-stop increments to mirror the setting of your camera. You can change exposure settings after reading and the meter will automatically compensate to maintain the proper exposure. And the extended sensitivity range, EV -2 to 22.9 for ISO 100, allows taking exposure measurements in virtually any kind of light. Flash Light Metering Shutter-priority readings of flash light can be made with a synch cord or cordlessly at shutter speeds from 30 minutes to second. The L-358 automatically resets after each reading in cordless mode to enable fast adjustment of flash brightness. The multi-flash function enables accumulating an unlimited amount of flash pops for times when a single flash pop cannot achieve the proper exposure or the amount of depth of field needed for the subject. Optional Radio Flash Triggering Simply plug the optional Sekonic RT-32 Transmitter Module into the battery compartment and wirelessly trigger flash units up to 100 feet away. The transmitter offers 32 digital coded channels and Quad-Triggering Zones and is compatible with PocketWizard radio triggering systems, as well as the PocketWizard Wireless Freedom partners.

Sekonic L-758dr DigitalMaster
programmable for exposure perfection Reflected Light Spot Metering The Sekonic L-758dr incorporates a precise 1-degree, reflected light spot meter. Reflected light metering tells you about the subject. Different from incident light metering that produces readings only for the middle of your cameras exposure range, reflected light metering can also show you where the edges are. The key to working with the L-758drs spot meter is knowing the dynamic range of your camera. That is, the tonal range your camera is capable of recording. Program this into the L-758dr and you can easily know which details will be properly imaged and which will be over or under the range of your camera. Armed with this knowledge, you can make exposure decisions that take full advantage of your cameras imaging capabilities to produce pictures with greater tonality and clarity than you have ever known before. Digital Photography: Boundless Possibilities Todays High Dynamic Range (HDR) processing enables breaking through the limits to produce results never seen before. Knowing your cameras capabilities and precise exposure readings with the L-758dr will help you make right exposure settings and save you time in processing. The picture of this Mexican plaza and church was created shooting multiple images and merging them in HDR processing.

Three metered exposures were made: Standard exposure, biased for highlights, and biased for shadows. These images were merged to produce the HDR image on the left. Jim Zuckerman

Sekonic Prodigi Color C-500/500R
Color control for digital and film Controlling the light in front of your camera is the first step in your color workflow. As long as you are working with a single light source, you can count on the white balance function of your camera or computer to get the color you want. However, add a second light, a light modifier, or work on location with todays mix of tungsten, halide, vapor and fluorescent lights, and you will either have to fix it up front or fix it later, if you can. How do you arrive at a common, single color tone that is easy for your camera or software to correct? How do you introduce additional flash illumination in the foreground without making it look like, well, additional flash illumination? And knowing that the color accommodation of your eyes and brain make unaided color adjustment nearly impossible to judge by yourself, how do you know how much color filtration is enough and when youve over corrected? If color is important, a Sekonic C-500 Series color meter should be in your arsenal of photographic tools.

Digital and Film Compatible The PRODIGI COLOR C-500 and C-500R measure and display color temperature and compensation values in LB/CC index or filter numbers for both digital and film cameras. In Digital mode, the color temperature and compensation readings are based on human visual response. In Film mode, readings are based on the color characteristics of traditional photographic film. By engineering the spectral characteristics of both systems into a single meter, Sekonic designers have given you greater control over lighting and color reproduction than ever before, regardless of your medium.

Wave Length (nm)
Engineering a meter to accurately measure color for both human visual response (digital sensors) and the characteristics of photographic color film required more that just creating a new set of algorithms to process the data. Properly measuring red intensity was a major hurdle. Sekonic designers solved the problem by incorporating four color sensors: a Red sensor for visual/digital response (Rd); a Red sensor for photographic film response (Rf); a Green sensor (G); and a Blue sensor (B). They then developed a new Simulated Spectrum software solution (patent pending) that emulates the blue and green channel color response for both digital and film.

Brightness and Color Value Display
Illuminance Measurement The brightness of continuous light sources is displayed in LUX (lx) or foot-candle (FC). Illuminance measurement is especially useful for cinematography, videography, theatrical and other applications that require precise control of light source brightness.
Color Temperature Display (in Kelvin) The color temperature is displayed for human visual response in Digital Mode or the spectral response for photographic color film in Film Mode.
LB/CC Index Display The LB (Light Balancing) in MK-1 (Per Mega Kelvin equivalent to Mired) and CC (Color Compensation) Index correspond to light source filtration systems. This simplifies the selection of amber (CTO) or blue (CTB) filtration as well as the amount of magenta or green (CC) filtration needed to balance the color of the lights you are using. Also, the correction values can be directly entered into the color adjustment mode of some professional DSLR cameras. LB/CC Filter Number Display Used primarily for film applications, amount of lens filtration needed is directly indicated in both LB (Light Balancing) and CC ( Color Compensation) filter values. The display can be adjusted to read out in KODAK Wratten, LEE or FUJIFILM filter systems in the custom setting MENU.

Other Functions

Flash Color Measurement Simultaneous color measurement of flash and ambient light is available in non-cord, cord and wireless modes at synch speeds from 1 to second.
