3） Light Analyzing Function

With a single measurement the ratio of flash light and fixe d light are displayed. If flash light is measured, the measuring value will denote the tot al intensity (a mixed value of flash light and fixed light). Li kew ise, t he component ratio display numerically shows in increments of 10% the ratio of flash light against the tota l intensity. This numeric value can be used to calibrate shooting to suit the artistic intention – for example, when shooting w it h a flash in a room lit by tungsten lamps, the tungsten lamp light (fixed light) can be strengthened or weaken ed (flash effect strengt hened).

5-3 Measuring with Radio-c ont rolled Flash (for L-478DR only)

5-3-1 How to Measure Using Radio Control

The measuring method using radio control involves connecting a radio receiver ( sold separately) to the flas h i n or der t o t r igger the flash from the main unit side. This enables one person to be able to measure the flash without the use of a synchro cor d. The following are the modes t hat can be set to measure this way.

・ Radio Flash Mode ・Radio Flash Accumulative Mode

Note that prior to measuri ng t he R adio Control channels must be set. ( See P51 for details.)

※ Radio receivers compatible with L-478DR: PocketWizard

manufacturers that equ ip flashes with PocketWizard systems. Please read the manual p r ovided with the radio receiver for details about operating the radio receiver. For compatible products, please se e the LPA we bsite (www.pocketwizard.com).

Caution

● The controllable distance of flash-compatible r adio systems varies in accorda nce with the position and direction that the radio receiver is set. To set t he best parameters, be sure to set up the main unit and the radio receiver in the following way.

1. Make sure the main unit and radio receiv er ar e visible to each other in a straight line.

2. Set up the radio receiver away from lar ge metallic objects, concrete or objects containing

a lot of moisture (people or wood, etc.).

3. Use Velcro tape or the tripod sl ot to secure the radio receiver. At this time, make sure the

radio receiver’s antenna is fully above the power source box of the flash. In all situations, do not allow the radio receiver’s antenna to come into contact with metallic objects.

4. Depending on the location, there ar e cases w hen the radio receiver absolutely cannot receive a signal. The causes are varied and include radio waves being reflected off of nearby objects. Normally, this can be rectified by changing the direction of the radio receiver by several centimeters. Alternatively, check to see if the radio receiver is behind an object that absorbs or blocks radio waves, such as concr et e, metal or low hill.

5. Under the above parameters, use r adio control at a distance within 30 m et er s.

Example of illumination ratio measuring using the Monitor Function (i n Shutter Speed

Priority Mode with incident light system):

When measuring illumin ation ratio of the main light source a nd fill light source, use the Flat Function (lumisphere ret r acted) to measure.

1） Rotate the Lumisphere retr acting ring ② until fully

switching to the flat position.

2) Turn ON just the main light source. Place the Light Receptor Head close t o t he subject and point it toward the main light source.

3) Touch the Average tab（）at the bottom of the screen. the Ave mark will appear on screen, and the main light source value will bec om e t he standard value. When the Average Function is running, the Average icon

will be displayed in the negative . . 4） Next, turn ON just the fill light source.

Now, point the lumisphere at t he fill l ight source, hold down the Measuring button ⑧, and the difference between measuring values for main and fill light sources will be displayed as an EV value. Simultaneously, the memory value and monitor value (compared location mea suring values) will be displayed on the Analog Scal e, enabling you to get an illumination ratio (cont r ast ratio).

・ Synchro Cord

This is a three-way, five-meter long cord that sync connects light meter, flas h and camera, which is great because there is no need t o replug cords when shooting. Also, one of the synchro cord’s connectors has a lo cking mechanism to prevent disconnection. (Cord has two male connectors and one female one.) The connector with the lock function is a male one.

・Standard Gray Card

This is a gray card (110mm x 10 2mm) with 18% reflection ratio. 1

With this card, you can check the standard measuring value during shooting.

By using the standard gra y card to determine standard exposure for results of meas ur i ng, you can acquire the exposure data that will provide faithful color reproduction.

・Exposure Profil e Targe t

This is the test chart (260m m x 1 60mm) used to create camera exposure profile s. The front features nine types of gray patches including bla ck and w hite ones, while the rear is 18% gray card, so it can be used t o det ermine white balance for digital cameras and exposure with the reflected light system.

・Exposure Profil e Targe t Ⅱ

This is the test chart (350m m x 1 20mm) used to create camera exposure profile s. The front features 25 types of gray patches including wh ite and black ones, while the rear is 18% gray card, so it can be used to determine white balance for digital cameras and exposure with the

10. Usage Precautions

Caution

● To avoid damaging this meter, never drop it or subject it to shock.

● Avoid using it in water spray or rain as doing so may cause damage.

● Avoid storing it in high-temperature and/or humid locations as doing so may cause damage.

● Beware of condensation caused by sudden temperature change, as such condensation may

cause damage or malfunction.

● If the temperature of the meter drops to -10 deg. C or beyond, response of the LCD becomes

extremely slow and displays are difficult to read. At temperatures between 0 and 10 deg. C the

LCD will become somewhat slower than normal but this does not hinder usage. Also, when the

temperature exceeds 50 deg. C, the LCD will turn black and will be hard to read. This will return

to normal when the temperature returns to normal.

● Do not place the meter in direct sunlight during midsummer or near heaters, etc., as the

temperature of the meter will rise beyond that of the air temperature. Be careful when using

the meter in hot locations.

Maintenance Notes

● If your meter is splashed with water, wipe immediately with a soft dry cloth. Leaving the meter

wet may cause rust or corrosion

● Keep the light receptor head away from dust/dirt and avoid scratching as accuracy may be

affected.

● When light meter gets dirty, clean it with soft dry cloth. Never use organic cleaners (like thinner

or benzene).
