What to use to backlight translucent surfacing materials?
The solution is to back the light guide away from the glass about 1 in. by putting down 1-in. clear acrylic square rod as spacers. Making up for the additional step when using white colors of these more translucent materials is the fact that you can use RGB LED lights to make them any color you desire, or even change colors.
What happens when you light a translucent element from the front?
If you light a translucent element from the front it will look pretty normal as the light will reflect naturally. Lighting translucency from behind means the light is refracted, (bent,) and scattered before your camera’s sensor records it. As you can see from the two example photos of the mad scientist with the red liquid in the flask.
What does lighting translucency from behind mean in photography?
Lighting translucency from behind means the light is refracted, (bent,) and scattered before your camera’s sensor records it. As you can see from the two example photos of the mad scientist with the red liquid in the flask. Notice how the color of the liquid appears very different in the two photos.
Can a photograph be taken with a translucent element?
When you photograph refracted light passing through a translucent element your camera may not give you an acceptable result if you are using any of the automatic modes. Being in control of your exposure manually will allow you to experiment and set it to give you the result that you think looks best.
What kind of material can be used to diffusing light?
However, LEDs can be particularly challenging for lighting designers since LEDs create “hot spots” of focused light that can detract from the visual appeal of a fixture. Special grades of acrylic sheet, polycarbonate sheet, and polycarbonate film are engineered to diffuse LED hot spots without sacrificing light transmission.
What kind of light is in a translucent curtain?
The only light is an emission plane outside and over the window. (clik on the images to enlarge) If we add a translucent curtain we get a lot less light illuminating the room. Adding transparency will allow more light into the room, but will make the curtain “see-trough”.
What does it mean when light passes through translucency?
Translucency (also called translucence or translucidity) allows light to pass through, but does not necessarily (again, on the macroscopic scale) follow Snell’s law; the photons can be scattered at either of the two interfaces, or internally, where there is a change in index of refraction.
