How to shoot the rainbow and Buddha's light during the trip?

Rainbow is a physical phenomenon that sunlight is refracted by water mist. It often appears after rain, waterfalls, fountains and other places with water mist, and is generally visible along the direction of the sun.

In summer, after the rainstorm, a rainbow appeared on the beautiful Xizi Lake. What an unforgettable wonderful picture!

To shoot a rainbow, we must first understand the appearance conditions of the rainbow.

1, there is sunshine after rain, which is often seen in plateau and summer. Then there are waterfalls and fountains, and it is easy to see the water mist when the wind blows.

2, smooth, that is, the sun shines on the water mist and is in a straight line with the photographer. When the angle between the sun and the ground is about 45 degrees.

It is better to shoot the rainbow background in dark color. For blue sky, dark clouds, tall pine trees and cliffs, you can darken the sky with a polarizer to reduce some reflections, so that the rainbow will be more obvious. The rainbow appears for a short time, so hurry up when shooting. When shooting a composition, you should combine the scenery or people. Otherwise, a single rainbow appears on the screen, which is monotonous, unsightly and without artistic conception, and even can only be attributed to information films.

If we trust the exposure meter too much, the color saturation will be weakened, so we should reduce the exposure appropriately so that the rainbow we shoot has saturated colors. You can also try to shoot rainbows with lenses of various focal lengths and try various compositions. For example, you can show a complete rainbow with a 16 mm lens, and one end of the rainbow can be photographed perpendicular to the ground with a 200 mm lens.

First, we need to know what a rainbow is. Rainbow is an arc-shaped ribbon formed by the refraction of light through raindrops, waterfalls or water vapor. The outer ring is red and the inner ring is purple. Rainbows often appear in the opposite direction of the sun and the moon (although such rainbows are extremely difficult to see), and the water surface reflects sunlight. On the periphery of a major big rainbow, a small rainbow with opposite colors will be formed. The width of the rainbow is inversely proportional to the size of the water droplets.

After the storm, the sun came out, or although the sun was shining, there were rain clouds in the distance. At this time, no matter what you are doing, you should leave immediately to look for the rainbow. After finding one (or more) rainbows, look for an ideal prospect immediately to make rainbows stand out. You can use a tripod if possible, and a polarizer is essential. Like most professionals, surround exposure can be used, especially when shooting color positive films. You can overexpose one level when shooting negatives. If the brightness of the rainbow in the developed photo is not enough, you should be prepared to argue with the photo maker. In order to pursue the best effect, it is best to find a familiar photo company to make it.

Find a rainy, foggy or cloudy place, or a waterfall or fountain. Turn your back to the sun until the shadow of your head is in front of you. At this moment, you are facing the sun. Spread your arms at 90 degrees to your sides. The rainbow will appear in front of your arm at a 45-degree angle. Roughly, it should be at the middle point between the arm and the shadow, about 45 degrees. In this range, the position at an angle of 42 degrees from the point facing away from the sun is the direction in which the rainbow appears. A small rainbow may also appear at an angle of 5 1 degree and may be photographed. You won't see a rainbow on the horizon unless the angle between the sun and the horizon is less than 42 degrees.

In nature, when the sun shines on the raindrops in the sky at a certain angle, the light passes through twice refraction and once internal reflection on countless raindrops, and then reaches people's eyes, and people see the rainbow. Because long-wave light refracts the least and short-wave light refracts the most, the outer edge of the rainbow is always red and the inner edge is always purple.

Rainbow is a physical phenomenon of sunlight refracted by water mist, which often appears in places with water mist such as waterfalls and fountains after rain. In our country, thunderstorms or showers mostly appear in summer, so people generally can't see rainbows in winter. Because such thunderstorms or showers usually occur after noon, rainbows are most likely to appear in the afternoon to evening. When there is a thunderstorm or shower in your place 2-4 hours before sunset, and the rainfall range is not large, when it is possible to leave the place before sunset, when the solar energy comes out of the clouds, you have the basic conditions for a rainbow.

Once you feel that there is a possibility of a rainbow, you'd better take a tripod with you in addition to the necessary cameras and lenses before you leave. Only in this way can you ensure the quality of your picture. In addition, rain gear is also essential.

Exposure is like shooting a sunset, so that the rainbow we shoot can have saturated colors. If you trust the exposure meter too much, the color saturation will be weakened, so you should adjust the first aperture or shutter speed to reduce the exposure. If the sky behind the rainbow is dark (which happens from time to time), you should narrow the aperture by half a step. Of course, the exposure required for rainbows may be different in different regions and under different weather conditions. When shooting with a digital camera, you can adjust the exposure combination at any time.

In composition, you can try to use lenses with various focal lengths. For example, a 16 mm lens can display a complete rainbow, and a 200 mm lens can shoot one end of the rainbow intersecting vertically with the ground. Any zoom lens can easily change various compositions.

Another natural phenomenon similar to rainbow is "Buddha's light", which is formed by the diffraction and diffuse reflection of sunlight on the surface of clouds. Its essence is that the sun projects the figure behind the viewer onto the cloud in front of the viewer, and the tiny water droplets in the cloud form a unique circular rainbow, in which the figure is among them. The appearance of Buddha's light needs the combination of sunshine, topography, sea of clouds and many other natural factors, and only a few places with the above conditions can enjoy it. The shooting technique is roughly the same as that of rainbow.
