A neutral density filter that reduces the strobe output by [4 EV].
A color filter converting strobe color temperature to 4600K. This filter
can enhance healthy human skin underwater and bring out the colors of
warm-toned subjects. Also, shooting RAW with the camera's white balance
set to 4600K, can enhance blue background while the subject illuminated
by the strobe remains in its natural tones.
Effective in the following situations:
- When a subject is extremely close to the strobe
- When shooting with a wide aperture setting
- When using ultra-high ISO setting
- When photographing light-emitting subjects
