10. 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 caus ed if the
projector is NOT in parallel with the screen or a previous misaligned Sheimpflug) . Take into acc ount that the consequence of
applying Scheimpflug correction upon a s creen not in par allel with the projector is that the projec ted image differs from the rectangle
shaped ima ge. In other words “distortion” of the projected image occurs. Masking will be required to solve the distortion.
The disadvantage of Mask ing is loss of content. Th erefore it is strongly rec om men ded to place the projector in parallel with the
projection screen and use the SHIFT functionality of the L ens 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 Scheim pflug can be applied.
