Why use a Variable ND Filter?
Neutral density filters reduce the amount of light going through the lens into your camera. By reducing the light you are able to achieve the following:
- Allows the use of slow shutter speeds, with high speed films or digital cameras, to record movement/image blur in subjects such as waterfalls, clouds or any fast moving subject
- Gives you full control over your depth of field. You are able to decrease depth of field by using wider apertures, which helps separate subjects from their background (subject matter in focus while your background is blurred)
- Allows you to shoot high speed film (above ISO 400) in bright outdoor situations by reducing effective ISO
- Enables cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
Do I need a filter for a digital SLR camera?
Although your images can be edited using imaging programs such as Photoshop, there are some filters that you just can not mimic its results in imaging programs. A suggested type of filter is a UV or Ultra-Violet.
While ultraviolet light is invisible to the human eye, it can nevertheless show up on a film image as an undesirable blueish cast; it can even result in a blurring effect.
Recommended to be used as a means of protection for the lens (digital slr included), these filters can be left on at all times as it is completely clear and will not change the colour or density of light. Ideal for photography of expansive spaces like mountains and sweeping landscapes.
