Reflective Glass Reduce Ambient Brightness
In many cases, we had to shoot across the glass: on the road, in the car out of the landscape; museum, across the window to shoot exhibits; aquarium, across the glass fishing ...
Across the glass shooting will bring a lot of problems, and Reflective Glass is one of the most serious problem, will make your photos appear on many of the virtual shadow, a serious impact on the screen.
In the need to take the glass shooting the occasion, how to minimize the elimination of Reflective Glass, we must solve the problem.
Today to tell you about the four reduction, the elimination of Reflective Glass method, so you can easily deal with the Reflective Glass problem.
1 away from some
Closer to the glass, can enter the lens of the less reflective. As close to the glass as possible to shoot, 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.
In the museum shooting exhibition items, close to the glass, with a large aperture, basically can completely eliminate the Reflective Glass, greatly weaken the existence of glass.
2 Reduce ambient light
Reflective Glass light from the photographer behind, 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 thing to say three times.
Not off the flash will shoot such an effect:
Turn off the flash after you need to think of ways to reduce the ambient brightness. In particular, can not let the ambient light than the glass side of the ambient light intensity.
If you do not pay attention to this point, 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 a good look, and then covered with a dark cloth, the use of the shutter line.
This action is not elegant, but very effective.
One of the greatest uses of polarizers is the elimination of reflections. After entering the digital age, we use the polarizer are basically circular polarizer (CPL).
CPL is usually composed of two rotatable rings, with a serrated lower ring from the fixed role, used to fix the polarizer 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.
