One, about black card

1. What is black card

Black Kat

As shown on the black card, not reflective of the fog surface material can be, I suggest the use of the file folder of the black plastic cover down cut, plastic material more frivolous also not easy to damage, size is not stipulated, I was cut into a 20x15 centimeter.

2. Time to use Black card

When the upper and lower light than the contrast is too large, simply to the dark part of the light on the basis of a serious waterfall, or light on the basis of the dark when the black to no details, common occasions for: sunrise, Dusk, night, streams and so on.

3. Auxiliary filters

Auxiliary filters

Black Kat is used to shake and some people use, how to make this action is the key to smooth completion, in order to avoid the speed of the black card can not keep up with the shutter time so use some filters to increase the shutter time, this is to improve the probability of success; common filters are CPL, ND.

Ii. Mode of operation

Common scenes generally to the water level as the demarcation point, first cover the bright part of the rhythm of the shaking (one second can have 4-5 times the best), that is, the scope of the shaking need to exceed some of the demarcation point (such as the demarcation point under 0.3 cm) This can make the transition more natural.

1. To the distance oyster frame with the water level as the demarcation point.

2. Light the first mode of light metering,. F18 the dark part of the light is 0.4 seconds and the bright part is 1/15 seconds.

3. Because 1/15 seconds is too short to operate the black card, so add two Lee 9ND minus 6 light so that the dark exposure time to become 1.6 seconds, the bright part is 0.25.

4. Adjust to M mode set the aperture F18 shutter for 1.6 seconds.

5. According to the black card operation way at the demarcation point (red Line part) shakes the black card; the formula 1.2.3, 4 each syllable 0.25 seconds, so one second can be divided into four syllables, such as: 1 (0.25 seconds). 2 (0.5 seconds). 3 (0.75 seconds). 4 (1 seconds) 2. (1.25 seconds) 2 (1.5 seconds), 3 (1.7 5 seconds), 4 (2 seconds), and so on.

This picture will be picked up by the black card at 1.25 seconds of light metering and can get the correct exposure of the upper 0.25 seconds lower 1.6 seconds.

1. Take the distance horizontal as the dividing point.

2. Light the first mode of light metering,. F20 the dark part of the light is 3 seconds and the bright part is 1.6 seconds.

3. This exposure value without any filter can be used to shake the black card, but I add two Lee 9ND minus 6 level of light with a CPL (minus 3 light) so that the dark exposure time to become 28 seconds, the light part of 5 seconds, mainly to create the atomization effect of the waves.

4. Adjust to M mode B shutter set good aperture F20 shutter 28 seconds.

5. Cover the upper half of the black card to 23 seconds after pulling black card, and then exposing the upper half of 5 seconds, get the upper 5 seconds lower half 28 seconds of exposure value.

A: The gradual reduction of light mirror general 3-level light, according to the actual operation is very few opportunities to use the gradient dimming lens can be photographed up and down exposure are normal photos, can not say no but the opportunity to wait for the right time, so the black card can be more than a few shots.
