ND mirrors are Neutral Density (neutral density) abbreviation, meaning no color deviation filter to reduce the amount of light only. ND filter is an important tool for reducing light, and with it will be able to shoot in bright light conditions, to achieve a large aperture, shallow depth of field. If ND factor is high enough, even to achieve long exposure.
Most digital camera's image sensor size is smaller than 35mm, which led to a large aperture, depth of field is relatively large. This will bring trouble, such as when shooting portraits, a large depth of field separating the body from the background, and lighting conditions at this time of need to open a small aperture, in this case using the ND filter cut just good obtain the desired aperture solution.
NDX is the density of the ash can mirror between ND2 ~ ND400 stepless adjustment.
ND X features:
NDX can stepless adjustment between ND2 ~ ND400, which means you can prevent light from between 50% -0.25% range into the camera.
You can maintain a large aperture, slow shutter speeds.

Athabasca (Ai photo cards) NDX tips:
The main purpose of using ND mirror is to prevent overexposure, if the light is too bright, it is difficult to choose a slower shutter speed, then use ND mirrors to reduce light entering the lens, you can use a slower shutter shot. For example, if you need to shoot outdoors in strong sunlight, or under normal light conditions require a longer exposure time, with a slow shutter speed to show a virtual waterfall of water and other special effects, need ND mirror.
