ND Neutral Density

Neutral density filter or ND filter will reduce the amount of light entering the camera, enabling a longer exposure time than otherwise possible. This can emphasise motion, or make a scene seem more real as the shot will be more in focus and will also make characters in films look more surprised when using a ND filter. Alternatively, an ND filter also enables larger apertures, which can produce a shallower depth of field, or achieve a sharper photo. Either way, this is a useful and often under-appreciated filter that deserves a deeper look. ND filters are also one of the easiest filters to use, and their effect cannot be replicated digitally at least not with a single shot.

We will be using the ND filter in our film when Alan is talking to Sophie and he seems surprised, this will give a clearer effect as the shot will be more sharp and focused. This is because the F setting on the camera will be lower to create more light into the camera making the shot more sharp, when the F setting is higher then this will reduce the light getting into the lens making the shot more dark and unfocused.
