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.
