When shooting a total solar eclipse, how to shoot a "sugar gourd string"

The effect of candied haws string is realized by a camera that can be exposed many times. Cameras that can achieve multiple exposures are generally film SLR, and some high-end digital SLR also have this function.

Total solar eclipse shooting gourd string:

1, method:

It used to be extremely troublesome to use a film camera.

The camera should have multiple exposure function, calculate accurately in advance and strictly control the exposure time.

It is simple and convenient to take multiple photos from before the "first loss of contact" to after the "last contact" and cut and splice them with PS.

2. Filter:

Budd film, welding filter and X-ray film are all acceptable.

3, focal length:

135 is not enough, at least 200, the bigger the better.

Extended data:

Matters needing attention in shooting total solar eclipse:

1. Even during the partial solar eclipse, the sunlight is still very strong, so you need to use a filter that weakens the sunlight by thousands of times.

Because the image of the sun is very small, we should use as large a magnification as possible.

3. It is necessary to stabilize the camera and control the shutter with the remote control or cable release.

During the total solar eclipse, the intensity of sunlight will be reduced by 10,000 times. Take off the filter quickly and adjust the camera (F 1 1. 1/30 can be used for shooting).

Because the total lunar eclipse is short, we should race against time and shoot as much as possible.

6. When generating light, quickly install a filter to protect the camera. It is best to use a film camera.

Features: short time, large brightness change in the whole process.
