Filming with projector I want to make an educational video. I am using a camera (Canon 250d), a projector, and some lights. 

The problem is that when I brighten the room or make light on the speaker, the text on the projector gets difficult to read. 

What can I change with my camera settings or the light setup to change this. So the room is bright and the text on the projector is easy to read.
Try adjusting the brightness and contrast of the picture on the projector. And it’s better to play with the light - direct only at yourself, not at the screen.
