ADVANTAGES: - For longer exposures - without changing the aperture, the filter provides the freedom to change the shutter speed according the effect desired.
For wider apertures - allows wider apertures in over-lit conditions be used to decrease depth-of-field, literally focusing more attention on the subject.
Preventing overexposure - even with a shutter speed of 1/8000 seconds, a large aperture of f/1.4 or f/1.2 can cause overexposure. With the variable density filter, overexposure issues can be avoided by adjusting the light intake.
