How to take a night view with a mobile phone? How to shoot the moon in the night sky and how to shoot the night scene clearly?

First, how to shoot the moon with a mobile phone

The moon itself does not shine, but reflects sunlight, so its brightness is very low. If the noon sunshine is compared with the bright moonlight of the full moon, the sunshine is 60,000 times brighter than the moon. The brightness of moonlight is extremely low, so it takes a long time to expose when shooting the moon scene. However, because the earth is constantly rotating, long-term exposure will make the moon in the picture move and form a light band. So generally speaking, shooting the moon scene uses two exposures.

Attention when shooting:

1, general cameras are equipped with multiple exposure devices. Double exposure method is to make two exposures on one film. For the first time, the scene was exposed according to the brightness of the ground scene, and the scene in moonlight was photographed, leaving the position of the moon above the picture. Then make a second exposure on this negative, and the moon will shine in its original position. When shooting the moon for the second time, if you want to enlarge the image of the moon, you can use a long focal length lens. In addition, because the moon is brighter than the scenery in moonlight, the exposure time should be readjusted when shooting the moon. If the aperture is used to shoot the moon scene for 2 or 30 seconds, the aperture can be used to shoot the moon alone for 2 or 2-3 seconds.

2. If the outline of the moon is shot too clearly, the effect is not good. So sometimes the moon is deliberately blurred, which has a halo effect.

3. You can also use two films to shoot the scenery under the moon and moonlight respectively, and then overlap and enlarge the two films. The position of the moon and the scenery under the moonlight should be arranged.

4, you can also use a negative, long exposure. If there are clouds in the sky, you can expose the scenery when the moon is covered, or you can shoot the moon after the moon is out of the clouds. You can also cover the moon with your hands during a long exposure according to the brightness of the ground scenery, and then take your hands off when the exposure reaches the last two seconds, so that the moon can be exposed on the negative.

You need to use a tripod to shoot the moon scene. In addition, when exposed for a long time, the failure of the reciprocity law of photosensitive film should be considered, and the exposure should be appropriately increased to compensate. If you use color film, you should choose long exposure color film. When exposed, because the reciprocity law is invalid, in addition to increasing exposure to compensate, filters need to be added to compensate for color.

6. When shooting with color film, you can choose light color film, the color is blue, which can render the moonlight atmosphere.

Second, how to take a night view with a mobile phone?

Night view mainly refers to the scenery under outdoor lighting or natural light at night, with lighting, fire and moonlight as the main light sources when shooting.

Pay attention to the following points when shooting:

1, keep the atmosphere at night. The light value at night is relatively low and the contrast of the scene is relatively large, so the exposure should be properly controlled. If the sky is too bright, or the brightness of the lights is overexposed, it will turn night into day and weaken the atmosphere at night. Therefore, the sky color of the night scene should be light black, and the exposure should be consciously underexposed. Generally, the normal exposure time should be reduced by 1/3 or 1/2.

2. Keep the real effect of lighting. The light source of night photography mainly comes from the light, so when you use it, you should show the lighting effect of the light. For example, when the light is near bright and far dark, its brightness decreases with the increase of the distance from the light source. This function should be retained when the flash is used for auxiliary lighting. You can use the aperture to control the brightness of the flash and feel the original light slowly. The direction of the flash should be consistent with the original direction of the light.

3. When shooting street scenes at night, in order to render the scene of busy vehicles, you can use the method of long exposure to make the lights of passing vehicles sensitive on the negative for many times. Because the car body is dark and will move, it will not be very sensitive to the light on the film, and the car lights will draw bright lines on the picture. The number and direction of white lines on the screen can be controlled according to the requirements of composition. Generally, lens covers are used when shooting. If the direction of the car meets the requirements, you can open the lens cover for exposure. If the direction of the car does not meet the requirements, you can cover the lens cover, which is not sensitive. When shooting, fix the camera on the tripod, cover the lens cover, then open the T door or the B door (the B door needs to be locked), take off the lens cover for exposure, and use the switch of the lens cover to control the exposure.

4. Night photography can use one exposure or multiple exposures. One exposure method is to fix the camera with a tripod, to control the opening and closing of the shutter with long exposure and cable release. Multi-exposure method is to make more than two exposures on a negative, which is often used in outdoor lighting shooting at night. When it is not completely dark, make the first exposure, which is less than the normal exposure. After the lamp is lit, make a second exposure. If you need to come and go, you can expose it many times. Be careful not to move the tripod during multiple exposures to avoid overlapping images.

5. When there is light in the picture, you can add a cross filter or starlight mirror to get the special effect of flashing and radiant lights. When shooting with color film, you can also use rainbow mirror or Constellation Mirror to obtain colorful color effects.

6. The asphalt road or smooth ground in rainy days can show the reflection of buildings and lights. If the buildings near the seaside, rivers and lakes are photographed in the picture, the light on or around the shore can be brightened due to the reflection of water, and the outline of the scenery can be outlined, and the shooting effect is better with color film.

7. When shooting with color film at night, light color film should generally be selected. However, if the solar film is used, the color of the film is red and orange, which can better show the brilliant atmosphere of lighting.

8. At present, a new type of night photography lens is produced abroad, which is equipped with "image intensifier tube", which is an element that can amplify weak light to tens of thousands of times. So you can use a high shutter speed when shooting at night with this lens. If you use A, S and A400 degree films, you can use1/500 in bright moonlight; In the faint moonlight, you can use 1/60 seconds; Even in starlight, you can use the shutter speed of 1/4 seconds or more.
