To convey your arguments successfully, you need the audience’s full attention.
Until recently this was hard to achieve as large screen projection was only possible
in a darkened room, which broke the connection between audience and presenter.
Now, thanks to dnp’s optical screens, you can project high quality images in any
situation, including broad daylight.
Consider the advantages as a presenter: To start with, you can leave the lights on.
You are not blinded by the contrast between bright light from the projector and the
darkness of the room. You can maintain eye contact with your audience and read
their facial expressions. You can even clarify a point by drawing on a whiteboard.
What’s more, your viewers can take notes without straining their eyes.
