[teacherartexchange] slides and projecting


Date: Sun Jun 12 2011 - 12:25:41 PDT

The surface on which you project the slides or films or any media has
an impact on the quality.

When the college where I work replaced all the old school pull down
screens with modern white boards I noticed a decrease in sharpness.

A close look at the surface of the white board showed why. The
material was a plastic soft edge waffle weave material with a shine to

The projector in the ceiling leaves a white-out in the middle of
anything I project. The bright light can't be eliminated so I move the
students around the room to places where they can get a better view
with the least glare.

The waffle weave surface is nowhere near as sharp as the old screens,
sometimes called "diamond dust" SO my remedy is to bring my old
fashioned screen from home (circa 1960 model) which is diamond dust
and voila, sharp images. Not filling the whole wall like the white
boards do, but no glare and soft focus.

Count your lucky stars if the budget in your school does not allow for
some "improvements"

BTW is anyone infested with the latest version of Microsoft Word? So
many issues with incompatible software!

Hope everyone is having a great summer.

Oh, and next year the NAEA is here in NYC and I will be happy to host
a party at my house in Brooklyn.
