Troubleshooting External Auto Flash
When using strobes, depending on the particular shooting conditions, subject characteristics and
desired image characteristics, it is very important to consider the total light of, and balance
between both the natural ambient light and the strobe light. Also, it is necessary to keep in mind
the general characteristics of digital cameras and how the D-180 handles external auto flash.
Here are some common situations, with causes and possible solutions.
1) Macro Imaging
Problem Blooming, image highlights washed out, overexposed, too bright.
Cause 1 Because the amount of strobe light exposing the subject is small, the proportion
of natural light reflecting off the subject is greater. After the strobe stops firing,
when it thinks proper exposure has been reached, natural light continues to
expose the subject until the camera shutter closes, and the digital camera’s
exposure latitude is overcome.
Solution 1-2: Adjust camera to minus compensation, for example, from 0 EV (no
compensation) to –2 EV, etc.
Solution 1-2: If using Aperture Priority or Manual Mode, stop down aperture on camera, for
example from f/4.0 to f/8.0 or f/11 etc.
Solution 1-3: If using Manual Mode, increase shutter speed, for example from 1/60 to 1/125 or
1/180 etc.
Solution 1-4: Attach optional D-180 diffuser panel to strobe to decrease flash output.
Cause 2 When subject has depth there is a difference light amount reaching the front and
back, causing overexposure on the front or foreground, overcoming the digital
camera’s exposure latitude.
Solution 2-1: Adjust strobe to minus compensation, for example if the camera aperture is f/8.0,
set the strobe to f/5.6 or f/4-1/2 etc.
