Some Common Concerns Regarding Logo Lens
Question 1:
How to avoid the image distortion?
Answer:
Your projection angle is too steep.
The steeper your angle of projection, the more distorted the image becomes. If you can raise the projector closer to the level of your projection, your image will be less distorted. When your projector is positioned at an upward or downward angle relative to the projection surface, a landscape format artwork will appear less distorted than a portrait format. When you’re projecting from a sideways angle, however, the opposite is true.
If you can’t raise the projector, try increasing the distance to reduce the angle and minimize distortion.
Questions 2:
Why can’t I see black or dark lettering?
Answer:
If you’re projecting onto a dark surface, like a burgundy stage curtain or a black wall, darker colors won’t be visible. This is because dark surfaces don’t reflect light. The color black doesn’t let any light through at all so it won’t show even on a light surface.
Reverse black to white on your gobo. To ensure your resulting projection is bright and visible, choose lighter colors, like white or yellow, for your gobo. You can also add a white background. In this case, you see the shadow, which to the eye appears black because of the contrast to white. If you have a logo or other design with black lettering against a light background, simply reverse the colors so your lettering is white.
