11. Scheimpflug
When to apply Scheimpflug?
Only apply a Scheimpflug correction in case the overall focus of the projected image is not equally sharp (can be caused if the
projector is NOT in parallel with the screen or a previous misaligned Scheimpflug) . Take into account that the consequence of
applying Scheimpflug correction upon a screen not in parallel with the projector is that the projected image differs from the rectangle
shaped image. In other words "distortion" of the projected image occurs. Masking will be required to solve the distortion.
The disadvantage of Masking is loss of content. Therefore it is strongly recommended to place the projector in parallel with the
projection screen and use the SHIFT functionality of the Lens Holder to match the projected image with the projection screen. In
case the SHIFT range is not sufficient then the projector can be tilted and Scheimpflug can be applied.
