Ambient light affects projection contrast. The less extraneous light, the brighter and more contrasting the image.
It is recommended to close the windows with curtains during the day and dim the lights in the evening. Then the projection will be well visible on a large enough area.
If the ambient light is bright, you should reduce the projection area or choose a projector with a suitable light flux.
Projection surface. A light (white, beige, blue, soft colors) surface is recommended. It can be a painted wall, wallpaper, tiles, canvas and other types of surfaces.
If the surface is bright, dark or reflects light (a mirror), you can:
- use a more powerful projector,
- reduce the projection area,
- create live pictures by hanging photo frames with white sheets on that surface and making a projection inside.
