Today a customer asked me, if I purchase your wall interactive projection equipment, will there be shadows on the screen when playing?
I answered him, this is definitely possible. After all, projection projects light onto the wall. If you stand in front of the light, there will definitely be a shadow.
However, we can reduce the impact of shadows on the picture by using different projectors.
Projectors are mainly divided into long throw projectors and short throw projectors. To project a picture of the same size, a long-throw projector should be placed farther away than a short-throw projector.
As you can see, this is a telephoto projector. It is five meters away from the wall. When I stand in this position, there is already a shadow 1.5 meters away from the wall. Let's take a look at this projector again. It's a short-throw projector. It's 1.5 meters away from the wall. When I stand close to the wall, there's still 30 centimeters before there's a shadow.
What does that prove? Have you thought about it? In fact, the farther the projector is from the screen, the easier it is for shadows to appear on the screen. If you want to reduce the impact of shadows on the picture, it is best to use a short throw or even an ultra-short throw projector.
If you think what I said is pretty good, please give me a little love and follow me, and you can contact me via private message. thank you all
