When shooting large glass products, how to make the glass not reflect the background?

1. Make a tent with translucent white paper or white gauze to surround the subject, leaving only an aperture in front, so that the lens can aim at the subject from the aperture.

2. Add a layer of sulfuric acid paper in front of the light bulb to soften the light. You can also add a reflective umbrella, or use white paper as a reflector, hit the light on the reflector and shoot by reflection.

3. The background should be as simple as possible. The background should not be too close to the main tone. When shooting color films, it is not advisable to use too thick smoke as the background. Because the colored light of the background will be reflected on the subject, which will affect the performance of the subject.

4. The use of polarizers can also weaken or eliminate reflection. Put the polarizer in front of the lens and rotate it slowly until the reflection weakens or disappears from the viewfinder.

5. Use spray or soft soap. When shooting, spray the spray on the bright spot, and the bright spot 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. There is another way to draw soft soap. The effect of eliminating bright spots can also be obtained by diluting alkali-free soft soap and thinly coating it on bright spots. Pay attention to the cleanliness of the surface and soap bubbles when using, and don't see traces on the photos.

6. Cover your reflection with clothes, etc.

This is the most mindless method. Just wrap the lens in soft clothes. If there are curtains in the room, you can pull them up to block most of the reflection. If the hue is black, the effect is better.

7. Put a polarizer in front of the camera.

The most effective way is to put a polarizer in front of the camera. After rotating the angle, you will find that not only the glass, but also the reflection of the scene is filtered out, and the obtained picture will become clear. However, some glass itself will have special treatment, and light spots will appear under the polarizer. It is important to note that in this case, the polarizer can no longer be used.

8. Avoid using wide-angle lenses.

Try not to use a wide-angle lens without a polarizer. Because of the depth of field, stains on the glass will enter the mirror relatively easily and receive more reflections.

9, slightly longer focal length and large aperture lens

You can use a lens with a longer focal length and a larger aperture, and the glass near the lens will be blurred, whether it is reflective or dyed. But this kind of fuzziness is not easy to control, and it is easy to blur the subject. You can try this method more.

10, find the angle with the weakest reflection.

Mastering and controlling the angle can also effectively avoid reflection. You can move the fuselage left and right and adjust it to the angle with the weakest reflection.

1 1. The front end of the lens is attached to the glass surface.

If the above methods fail to achieve satisfactory results, the simplest and most effective method is to stick the front end of the lens on the glass surface, so as to minimize the reflectivity. Even with a super wide-angle lens, this method can get as clear a picture as possible. It's just that if you are in a car, be careful of the collision caused by bumps. Moreover, when the lens is attached to the glass, the viewing angle of the lens will be limited. If you adjust the angle, there will be a gap between the two. At this time, you can cover the gap with something like black flannel.

12, turn off the flash.

Turn off the flash when shooting through the glass. Either way, the flash won't improve the picture quality. It will greatly increase the reflection.

13, avoid indoor light sources.

When shooting night scenes indoors through glass, avoid indoor light sources, keep dark, avoid reflection, get as close as possible to the glass window, and then shoot regularly.
