Star-like material-how to make a star-like effect?

In night photography, pay attention to these points, and the effect of star gathering will be more obvious, you know? When shooting in the face of the sun, we can get a very attractive effect, which is often called the "star gathering" effect, as shown in the figure below.

Usually, when the lens is facing a strong light source (for example, in the sun or under a street lamp at night), due to the diffraction phenomenon, we will get the effect of light scattering around the light source in the picture. When taking portraits or landscapes, the effect of dots is very common and the effect is very good. So, how should we take photos of the star-awn effect? We will discuss it in detail in this article.

Use a small aperture to get a canopy effect.

If we shoot the starlight effect with the maximum aperture, it will only blur the background (foreground), because when the aperture is opened to the maximum, the aperture shape in the lens will become round, don't you understand? Look down. So what caused this star? This is an optical phenomenon called diffraction. Diffraction occurs when light passes through a small hole (small aperture) in the lens. As shown in the figure below:

When there is a big hole (large aperture) on the left side of the picture, the diffraction phenomenon is not obvious when the light passes through the big hole, but it will be especially obvious when the hole becomes smaller (small aperture). By the way, diffraction can also cause purple edges in photos.

When we reduce the aperture, the blades in the aperture will get closer together to form a polygon, and then through the diffraction of light, a star-studded effect will be produced.

Usually when shooting starlight effect, you need a small aperture, such as f/1,f/ 16, to create a beautiful beam. Generally speaking, the smaller the aperture, the better the starlight effect, but don't adjust the aperture to the minimum, such as f/22. Because the aperture is too small, it will cause problems such as low resolution and insufficient sharpness of image quality. However, at present, the lens quality is getting higher and higher, which is no longer a big problem. However, it is recommended to use the aperture of f 1 1 for shooting.

Reduce glare by partially blocking sunlight.

By narrowing the aperture, you can create a star-awn effect, but there are still problems. When the lens is facing the sun, it will also produce some glare, which will affect the starlight effect and make it less clean and tidy. At this time, we need to block some sunlight to reduce glare, and constantly look for the best "stars" by finding the right camera position. Below, there is a dazzling effect.

If there is no condition to block the sun, you need to shoot along the horizon, and the smog in the atmosphere will weaken the glare.

Not all the shots can shoot the perfect effect of holding the moon with the stars in the sun.

Usually, the more expensive the lens, the newer it is, and the better the anti-glare effect. The fixed-focus lens is better than the zoom lens. The effect of starlight depends on the number and shape of aperture blades in the lens. Even-bladed lenses produce starlight equal to the number of blades (for example, an eight-bladed lens will produce eight starlight), and odd-bladed lenses produce starlight twice as much as the number of blades (for example, a seven-bladed lens will produce 14 starlight).

Keep the lens clean and remove the filter.

Spots, dust or oil stains in front of the lens will increase flash and stray light. Ultraviolet mirrors or other types of filters can also increase stray light. If you have glare problems when shooting in the sun, be sure to remove all filters and make sure the lens is clean.

Don't just look at the sun when shooting stars.

Starlight effect is not limited to landscape photography and shooting in the sun. This effect can be produced when there is a bright light source. Shooting the moon at night is very suitable for the stars.

Ok, today's tutorial is over. Do you already know the skills of taking photos with the effect of "Starry Mountain"?

How did Nikon SLR take this photo of the sun? This star map is a little overexposed, and the sun spot is too big.

There are several key points in shooting stars, wide angle and small aperture.

The light ratio during the day is very large, so the gray gradient mirror can be used to balance the light ratio between the ground and the sky.

Shooting at night is relatively easy.
