Which gear is more suitable for SLR ND filters?

It is more appropriate to choose 3 stops and 8 stops for SLR ND filters. Level 3 is used for smooth water during the day, and high level is used for long exposures during the day. Generally speaking, when taking pictures of the water during the day, it is recommended to use 3 stops of ND, so that the shutter speed will be just right at ISO100, aperture 16-22. If it is not enough, use GND to make up for it.

Related effects:

1. Reduce the amount of light. For example, if it is difficult to shoot with a large aperture in a place with strong light, you can add a neutral gray filter.

2. Extend the shooting time, for example, if you want to shoot foggy water in a very bright place.

3. When shooting street scenes during the day, adding a certain number of neutral gray mirrors and greatly extending the exposure time can blur pedestrians or even completely remove pedestrians and vehicles.

ND filters only reduce the intensity of light, so it will not affect the color of the final image, nor will it affect the camera's white balance and automatic exposure. . Using an ND filter will not have any impact on the color and contrast of the subject. In addition, since SLR cameras meter light through the lens, the ND filter will not have any impact on the camera's automatic exposure system.

When it is necessary to artificially use a slow shutter speed or reduce external light, the ND lens is a very practical additional lens. Of course, since different lenses have different calibers, ND mirrors also have different calibers. When using them, you need to choose ND mirrors of different calibers according to the caliber of the lens.
