Yes and no. For the clearest and brightest picture the projector should be used in a completely dark room. A reasonably clear picture can still be achieved in dim light, but virtually no picture can be seen in a fully lit room. Note: Projecting photos requires a totally darkened room.
Shifting occurs because the photo or paper being enlarged is exposed to heat from the lamp, causing it to expand. Thus, the projected image appears to shift.
To minimize shifting, after setting your projector up at the desired range, let the projector run for several minutes before beginning tracing.
To achieve reduction with the Super Prism, the accessory lens #200-705 should be used. This lens reduces down to 80%. The Super Prism includes this lens.
The main difference between the Prism and Super Prism is in the lens. The Prism has a single-element lens with the projection range of 80% reduction up to 20 times enlargement, while the Super Prism has a three-element color corrective lens with the projection range of 3 times to 20 times enlargement.
The Super Prism lens produces a very sharp and bright image. It is ideal for projecting photos or highly detailed designs. (The Super Prism includes an accessory lens that will expand the range to 80% reduction). Both projectors have a copy size of 7" X 7" and 500 Watts of illumination.
Because of the limited height of the Prism stand you are not able to back up far enough from the tabletop to achieve any amount of projection. The Super Prism lens requires a minimum of 32" to focus (this measurement is the distance from the wall or other projection surface to the edge of the lens).
To achieve 20 times enlargement with the Prism the projector should be placed 14' from the projection surface. To achieve 20 times enlargement with the Super Prism the projector should be placed 16.5' from the projection surface. An approximate rule of thumb is every 9.5" away from the projection surface equals a 1-time enlargement.
No, but the range of enlargement can be increased by simply swivelling the upper assembly of the stand over the floor or lower surface. The Prism Stand is capable of 7 times enlargement onto the floor (from a 36" table). When doing floor projection, please make sure the table is sturdy enough to hold the projector in this position.
Because of the stationary positioning of the glass lens within the lens barrel, combined with the convex shape of the lens, a "gap" is created when reversing the lens for either enlargement or reduction. The size of the "gap" is 1.65 to 2.24 times enlargement. Therefore, 2 times enlargement is not possible because it falls within this gap.
The art is placed underneath the projector. The projector has a 5" X 5" opening that sits on top of the art.
Yes, the Projector Floor Stand can be used for wall projection with the Tracer. Simply set the projector in the provided stand platform. The Projector Floor Stand rotates 360 degrees, tilts 15 degrees front to back, and adjusts from 4 feet to 4 ½ feet high, allowing for more versatility in the capabilities in the projector.
