4) Distant Subject Imaging
Problem
Subject is underexposed, too dark.
Cause
Subject is too far away, beyond strobe's effective range so adequate light is not
reaching subject.
Solution 1:
Move closer to subject, to within the strobe's effective range.
5) Advanced Techniques (slow synch imaging / using
Problem
Blooming, image highlights washed out, overexposed, too bright.
Cause
The proportion of exposure due to natural light is comparatively greater, so that
even after the strobe stops firing at what it thinks is "proper" exposure, the
shutter is still open adding natural light exposure, causing total exposure to
exceed the camera's exposure latitude.
Solution 1-1: Adjust strobe to minus compensation.
Solution 1-2: Adjust other shooting parameters on the camera.
6) Advanced Techniques (back-lit subjects)
Problem
Difficulty to achieve intended image.
Cause
The balance of natural light to strobe light is improper for the camera shooting
parameters.
Solution 1:
Set strobe flash output compensation and camera exposure compensation
according to the subject reflectivity, background brightness and to what degree
the subject fills the frame.
compensation and strobe flash output to minus (-) compensation.
Adjusting D-180 Flash Output
It is not necessary to always exactly match the Aperture Value Set Switch to the camera's aperture
value. However, in addition to the various situations described
condition and the D-180 strobe position relative to the subject and camera, there may be a
difference between the subject reflectivity measured by the D-180, and the subject reflectivity
metered through the camera lens. Exposure difference may vary based on camera manufacturer
and camera model, as well as other factors.
To obtain optimum exposure in such cases, after double checking that the Aperture Value setting
on the strobe matches the camera aperture in the camera monitor, if proper exposure still not
obtained, adjust the Aperture Value Set Switch for flash output compensation as described below.
Note: In general, the images on consumer digicam monitors often appear a little overexposed, so to
