Ray effect photography
What the landlord said is the Tindal effect. First of all, we should know what the Tindal effect is. 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 Tindal phenomenon.
The landlord was misled by two other friends. It doesn't mean that you can shoot Dindar as long as you take down the hood and aim it at the light source. This requires certain conditions.
Let me talk about the shooting conditions.
It is best to choose shadows in the forest for backlight shooting, and the morning after rain is a good time to shoot.
In the early morning after the rain, the Woods are often filled with water vapor, and the humidity in the Woods will be even greater. So at sunrise after the rain, the sun shines through the gaps in the leaves, so that when we observe in the vertical direction of the light line, we can clearly see the slightly blue light pole. In the shadow of the backlight, the picture will appear very dark. Therefore, you can choose a darker place to shoot.
Using spot metering mode to measure the light at the highlight of the picture, the shutter speed does not need to be very slow, as long as it can reach the safe shutter speed of the camera. Therefore, in the early morning when the water vapor is sufficient, the forest is more likely to form the Tingdahl effect.
