Reflective Glass Get The Best Results
- Jul 01, 2017 -

Road reflective glass beads is a kind of recycled glass as raw material, after crushing by natural gas melting at high temperature and the formation of a small glass particles, observed under the microscope as a colorless, transparent sphere. The refractive index is between 1.50 and 1.64, and the diameter is generally between 100 microns and 1000 microns. At present in the domestic production of glass beads is the main process of flame floating method.

Road reflective glass beads as a road marking (paint) in the reflective material, can improve the road marking paint reflex performance, improve the safety of driving at night, has been identified for the national transport sector. When the car driving at night, the lights illuminated with glass beads on the road signs, the lights can be reflected in parallel to the light back, so that drivers see the direction of progress, improve the safety of night driving. Now, reflective glass beads have become a road safety products can not replace the reflective material.

Closer to the glass, can enter the lens of the less reflective. As far as possible close to the glass for shooting, can effectively reduce the scene behind the scene to reflect the probability of light.

Some people raised objections, "the lens by so close,Reflective glass polished how to do?" Think of a way not to let the lens directly hit the glass is not on it!

For example, in the edge of the lens affixed with a certain thickness of small objects, such as coins, rubber mud, etc., to achieve the glass surface and lens surface isolation.

Glass reflective light source from the photographer behind,Reflective glass think of ways to weaken the ambient light is the most direct and effective way.

First is the most important point, turn off the flash, turn off the flash, turn off the flash. Important things say three times.

Not off the flash will shoot this effect:

Turn off the flash is just the beginning, you also need to think of ways to reduce the ambient brightness. In particular, can not let the ambient light than the opposite side of the glass light intensity.

If you do not pay attention to this point,Reflective glass such as across the glass under the sunset scenery, the room is very bright, your photos will become like this.

If you can control the surrounding light environment, it would be better. Turn off the lights and pull on the curtains.

If you can not control the lighting conditions around you can use the occlusion method: let the lens close to the glass, take good scenery, and then covered with a dark cloth, the use of the shutter line.

This action is not elegant, but it is very effective.

One of the biggest uses of polarizers is the elimination of reflections. After entering the digital age, we use the polarizer are basically circular polarizer (CPL).

CPL is generally composed of two rotatable rings, with a serrated lower ring from the fixed role, for the polarizer lens fixed on the lens; rotating the upper circle can change the light angle.

When used to tighten the next ring,Reflective glass fixed mirror body, and then continue to rotate on the circle, facing the viewfinder observation, looking for the best extinction on the line.

So, is not using the polarizer, you can completely eliminate the glass reflex it? Let's take a look at the effect.

Take a picture of the glass. You can see the glass appeared on the obvious reflection, reflecting the clear image of the building.

You can see the reflective has been eliminated most of the glass after the scene is also very clear, but still can see some of the building's blur.

It can be concluded that the polarizer can significantly reduce the glass reflection, but can not be completely eliminated. Need to meet other means of reducing the reflective, in order to obtain the best results.
