How does Canon 600D shoot flashlight beam at night? How to set the camera?

Shoot the beam effect of flashlight with SLR camera. The parameters of the camera are suggested as follows:

1, small aperture (f8, f 1 1)-in fact, large aperture also has the effect of large aperture.

2. Don't point at the light source for metering-exposure lock after metering, and re-compose.

3. Low sensitivity (iso 100 is enough).

4, white balance according to personal preferences.

5. Exposure compensation can be adjusted to negative compensation-it doesn't matter if you don't adjust it, as long as you don't expose it.

First of all, this kind of photo mainly has a great environmental impact. Remember the Dindar phenomenon in chemistry? When a beam of light passes through the colloid, a bright "path" can be observed in the colloid from the vertical direction of the incident light. This phenomenon is called Tingdahl phenomenon. So there must be dust, smoke and the like in the air to refract the closing line, just like this one you uploaded. Moreover, the light source must be hard light, and finally there must be a barrier to block the light, in order to reflect clear light. Finally, it is easier to have such conditions sooner or later, or it will be sunny after the rain.

In terms of technical parameters, the first is white balance. Generally, this situation is easy to appear in the morning. When the fog in the morning is illuminated, it will refract blue because of diffused light. You can set the white balance manually to make this blue darker. It is more appropriate to set the color temperature around 4000K K k. If you set the white balance directly to the preset of "incandescent lamp", the picture will be too blue. When shooting, you can use spot metering mode to measure the brightness of the picture. The shutter speed does not have to be slow, as long as it can reach the safe shutter speed of the camera. Finally, generally need a small aperture, less than or equal to f 1 1. Small aperture naturally requires a slow shutter, and the sensitivity is preferably 50,100,200, so as to appear exquisite.

This effect is greatly influenced by the environment. I don't know if you understand it after talking for a long time. Learn about chemistry and physics, and find some books about photography and light effects to read.

I hope you make progress in your study.
