Audio Visual Projection focus Tips
Hello Guys,
I works as audio visual technician, mainly doing audio but getting in to video. I am trying to learn projection and tips on how to get perfect projection, I really don’t understand the geometry to it. Everytime I do the projection my image is never perfect. One side is always crooked. Does the projector have to be in the middle of the screen? should I zoom out all the way first than shift lense and get the image in the middle? what should I first be doing. Please all the experienced video/AV technicians please reply with tips on how to get started and understand projection. Thanks in advance.
