Reflective Glass In many cases, we had to shoot with the glass: the journey, in the car to shoot out the scenery; museum, across the window to shoot exhibits; aquarium, across the glass fishing ...
Across the glass shooting will bring a lot of problems, and glass reflex is one of the most serious problem, will make your photos appear on many faint, seriously affecting the screen.
In the need to take the glass shooting the occasion, how to minimize the elimination of glass reflective, we must solve the problem.
Today you are talking about four reductions, eliminating the glass reflective method, so you can easily deal with the glass reflective problem.
1 away from some
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.
It should be noted that the need to take some protective measures to avoid direct contact with the lens glass, scratched the lens.
The use of UV mirror, or in the edge of the lens with a certain thickness of a small object, the glass surface and the lens surface isolation, are a good way to deal with.
As above, in the museum shooting exhibition items, close to the glass, with a large aperture, basically can completely eliminate the glass reflective, greatly weaken the existence of glass.
2 Reduce ambient light
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.
The most important thing to 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:
After turning off the flash, you 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 very effective.
3 Use a polarizer
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, 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,Reflective Glass 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.
Rotating polarizer, reflective gradually weakened. Choose the weakest angle of reflection, and then take a picture.
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.
