Why do we need a Black Card?
Black card is used when there is a large exposure difference in a photograph. For example when your photo includes sky and ground, the sky will be easily over-exposed to preserve the details of the ground. In this case we can use Black Card to cover the sky and balance the exposure. Black card is also needed when shooting long exposure photos. When you are taking photos of sunrise, sunset or night scene, Black Card is a useful tool.
Black Card can be used in the following areas:
- Landscapes with large exposure difference (Applicable only to slow shutter speed. Otherwise GND is recommended.)
- Magic Hour (Sunrise, Sunset)
- Car Trail
- Smooth, silky water
Instructions of using Black Card
Before taking the photo, meter the upper and lower part exposure separately and calculate the difference (For example upper part needs 4 seconds while lower part needs 8 seconds). Expose the whole photo for suitable time before covering the bright area with a Black Card. Move the card quickly during exposure to blur the separate line.
Can a Black Card replace GND filter?
Basically we can not use Black Card when we are using fast shutter speed like 1/200s or 1/1000s as we have to calculate the covering time manually. GND will be needed in the above situation.
