Solution 2-2: Using strobe arms, move strobes farther away from subject to reduce amount of light reaching the subject.

Solution 2-3: Attach optional D-180 diffuser panel to strobe to decrease flash output.

2)Mid-range Subject Imaging

Problem Blooming, image highlights washed out, overexposed, too bright.

Cause 1 If the subject only covers a small portion of the frame, such as a small fish with an open water background, only a small amount of light will be reflected off the subject and back to the D-180’s light sensor. The strobe, sensing very little reflected light (under exposure) will try to emit more light than necessary, and overexpose/wash-out the subject. This is a difficult situation for any camera/strobe system.

Solution 1-1: Adjust strobe to minus compensation.

Solution 1-2: As needed, set camera’s exposure compensation.

3)Using Multiple Strobes (including camera’s internal strobe)

Problem Blooming, image highlights washed out, overexposed, too bright.

Cause 1 The total possible minimum light output from the combined strobe system (external strobe(s) + internal strobe) is too great at close distances, causing the close end (nearest the camera) of the effective flash exposure range to lengthen out, away from the camera. Subjects close to the camera/flash will receive too much light and be overexposed. This is particularly the case for camera’s having internal strobes with relatively large minimum possible flash output. For such cameras we recommend placing Clear Photo System film over the internal strobe when using external strobe(s).

Solution 1-1: Use Inon “Clear Photo System”

Solution 1-2: Stop down camera’s aperture value.

Solution 1-3: Adjust strobe to minus compensation.

Solution 1-4: Using strobe arms, move strobes farther away from subject to reduce amount of light reaching the subject.

Solution 1-5: Attach diffuser panel to strobe(s) to decrease flash output.

Cause 2 When using strobes other than Z-220 as TTL Slave strobes when the D-180 is the Master strobe, the effective exposure range is insufficient and/or the recycle time is too long (for use with pre-flash systems etc.) making proper exposure difficult or not possible.

Solution 2: Use Z-220.
