Equalization Adjustments

W ith all the variable factors above it may seem that performing the math necessary for

equalization is daunting. Here are some techniques for fine- tuning or adjusting

equalization times without using specific math:

On some 35mm cameras you can gauge timing without using film. If your camera

allows triggering with the film bac k open you can verify synchronization visu ally.

1. Perform the steps above to get basic equalization started

2. Point the flash at a blank wall

3. On the camera NOT attached to the flash, set the shutter speed to 1/60

4. Open that camera’s back

5. Point the camera at the same wall as the flash

6. As the camera and flash are being triggered look through the shutter plane

through the lens at the light from the flash hitting the wall. CAUTION: MAKE

SURE the flash is set to a comfortable level for your eyes!

7. Note the shape of the light burst. If it is a perfect bright circle then the cam era is

in sync. If the circle is dark or has a hard line running along one edge then the

camera is not in sync. The hard line is the shutter in motion while the flash is

still generating light

8. Adjust the shutter speed up or down until you see a perfec t circle

ë The delay time setting screen is instantly active. W hile in numeric entry mode

you can adjust the delay up or down and the displayed value will be executed on the

next trigger. Using the “through-the-back” method above or by shooting film, Polaroid,

or digital you can adjust the delay and view the results to more suit your specific

camera’s timings.

The mathematical formulas used thus far are designed for equalizing at 1/125. The

final offset number (0.0025 for example) may need to be adjusted when attempting to

equalize at faster shutter speeds or slower ones with wide lag variation cameras. The

offset number tries to move the flash burst to the middle of the exposure to

compensate for drifting lag time. Experiment with different offsets to fine tune your

shutter speed, flash duration, and camera timing combinations. Too long or short of

an offset and you limit a camera’s ability to get the exposure if the lag drifts, even by a

small amount.
