anamorphic lens; see Figure 3-25) or Button-head Height Adjustment Screws (Shasta
anamorphic lens; see Figure 3-26) on either side of the lens. Then, slowly move the
anamorphic lens into place so that there are no shadows on the top or bottom of the
screen:
When the vertical position is properly set, tighten the Height/Pitch Adjustment Knobs or
Button-head Height Adjustment Screws to secure the lens in place.
• Adju s ting the Pitch (Angle): Next, angle the lens to eliminate any top-to-bottom
pincushion distortion. To do this, loosen the Height/Pitch Adjustment Knobs (Whitney
anamorphic lens; see Figure 3-25) or Button-head Pitch Adjustment Screws (Shasta
anamorphic lens; see Figure 3-26) on either side of the lens to allow it to pivot freely.
Then, adjust the anamorphic lens angle so that the projected image is rectangular:
The anamorphic lens will almost always be angled with respect to the projector; this is
normal.
Once the proper lens angle has been set, firmly tighten the Height/Pitch Adjustment
Knobs or Button-head Pitch Adjustment Screws to secure the lens in place. For a
Shasta anamorphic lens, also tighten the Set Screws on either side of the lens to lock
the angle.
There may be some pincushion distortion even after the lens is
properly adjusted, especially at shorter throw distances. If this is the
case, Runco recommends that you slightly over-scan the image
into the screen frame area to mask the distortion.
