How to adjust the reflection of the camera?

What can a camera do to reflect the light from the glass of a photo frame?

Minimize indoor lighting. When shooting night scenes, we should make full use of indoor shadows and curtains, and cover the curtains on the camera to reduce the influence of the surrounding messy light. When shooting in the daytime, you can't use the above method because the curtain itself will produce images.

You can add a polarizer. A polarizer can filter out light at a certain angle. After adding a polarizer, the glass reflection can be filtered out.

When shooting in a dark place, don't turn on the flash, and don't have a light source in the mirror, for example, don't point the mirror at the window or light. I looked for several angles, and there were always some that were not reflective. I hope I can help you.

One is to install a polarizer on the lens, and the other is to pay attention to the shooting angle.

Consider using a polarizer, installed in front of the lens, to eliminate the reflection of glass by using the polarization principle of light, but at the same time increase the exposure, so that iso and aperture can be adjusted. Turn the polarizer to eliminate reflection.

Buy a polarizer (a kind of filter) and install it in front of the lens, and adjust the shooting (rotate it so that you can see where there is reflection, which will weaken or even eliminate it). The function of polarizer is to reduce the reflection of reflector; (Suitable for SLR cameras; Small DC cameras may not be suitable).

Use camera filters and polarizers. Polarizer, also called polarizer, or PL mirror for short, is composed of two pieces of optical glass and a tiny polarizing crystal with directional function.

When shooting, spray the spray in a bright place to eliminate reflection. In cold weather, you can also aim at the subject to breathe when you open the shutter, so that the surface is foggy white, which can also eliminate the bright spots.

When shooting objects with reflective surfaces, remember not to let the camera stand at the same angle as the light source. The trick to shooting reflective objects is to use a relatively large light source and place it opposite the camera position.

How to adjust the contrast of white light when the camera reflects light?

1. Exposure time: If the photo taken is too dark or too bright, you can adjust the exposure time to change the brightness of the photo. A longer exposure time will allow more light to enter the camera, and the photo will be brighter, otherwise it will be darker. You can gradually increase or decrease the exposure time until you are satisfied.

2. Take Huawei's mate30 and EMUI 10 systems as examples. The specific steps are as follows: Try to take another photo in a better light. You can try to adjust the camera, exposure value. First turn on the camera, find the settings in the camera, and then set the exposure value to 0 in the settings.

3. Open the material picture 1, select the menu "Image Adjust Brightness/Contrast" command, set it in the pop-up dialog box (Brightness: -97, Contrast: 100), and click OK.

It is white, isn't it? If the white coverage is wide, CCD is generally not acceptable. You can take it to the maintenance station. If the CCD is defective, it is estimated that you can replace it with a new one. I changed it once before, Canon's. It's all white, so it's hard to see what's in it.

5. You can adjust the brightness by adjusting the sensitivity, shutter time and aperture size. You can adjust the sensitivity and its influence on photography.

6. Some digital cameras have a single sensitivity, and their CCD sensitivity tolerance is very small, so the requirements for shooting conditions are harsh. In the case of too strong or too weak light, the use effect will be very poor.

What about taking pictures and reflecting light?

1. For example, using a polarizer can reduce the reflection of the water surface, so that the fish in the water can be photographed clearly. When shooting such a scene, the projection angle of the light source should be close to the projection angle of the camera, and the maximum deflection angle should be between 30 and 40 degrees.

2. A special spray device to reduce reflection during shooting. Spray the spray in a bright place, and the reflection can be eliminated. In cold weather, you can also aim at the subject to breathe when you open the shutter, so that the surface is foggy white, which can also eliminate the bright spots.

3. Buy a polarizer (a filter) and install it in front of the lens, and adjust the shooting (rotate it to see where there is reflection, which will weaken or even eliminate it). The function of polarizer is to reduce the reflection of reflector; (Suitable for SLR cameras; Small DC cameras may not be suitable).

If you want to take photos through the window in the room, the ideal way is to dim the indoor lights to contrast with the outdoor environment. You should know that if the indoor light is stronger than the outdoor light, there will be reflection, so dim the lights.

5. If the photo reflects light, turn off the flash and use other light sources when taking photos; Or try to use a side view angle when taking pictures to avoid light reflecting into the lens.

6. The mobile phone reflects light because the lens is not good and the filter is not complete. Especially bright is ci light, which is also called eating. The solution is: take off the back cover, first take out the card slot, remember, then unscrew the two small screws below, and be careful not to drag the line.
