I am going to shoot a pair of short films where both directors want
to use videoprojectors. One of them wants to use the projection
as the scenery in a theatre and the other wants to project video
on the face of a person. I am not 100% sure if the video will look
ok or it will be a very low light to register on film.
Can anyone give me an advice or has any one experience doing this
type of situations.
There are many creative ways of using video projection for theatre
sets or film background scenery. The issues of light levels will
be a function of the choice of projector. If it is a theatre set
you would need a larger projector to fit that venue but a film shot
only requires a projection size to match the frame unless of course
if you plan to track or boom through a scene. Back projection through
translucent screens will give you good light levels with less ambient
light gain. You can use smaller projection areas by creating the
video to fit theapplication without stretching the capability of
The "On face" projection can be done with a unit as small
as the 2.2 pound Plus projector which will give you 1000 k lumens
at 2000:1 contrast ratios in hi-def if you want. Depending on the
budget you can go all the way to 1080 hi-def digital projection
at 40kb/s which is twice the rate o fcable HDTV . The video content
is just as important as the projector and can be a major production
in it's self. There are many techniques for video projection in
theatre sets that can sizzle, but if it over shadows the production
it is no longer theatre, it's only a movie.

As always the first piece of advice is :
Testing Testing Testing
There are several types of video projectors and each has a different
way of making us see an image.
Your best bet is with an LCD projector, they have the least artefacts.
As a light source you will probably want the brightest you can get,
it can usually be turned down some if needed. Do be careful about
getting the talent in the eyes with a bright projector, they can
cause damage even with a dark image. If projector is close to them
and the lighting is subdued you could use a smaller projector. The
little portable desktop projectors can be cool for putting a computer
screen image on a face.
For the scenery trick, you will be light challenged if the image
gets too large or the scene wants to be too bright. For that you
will want one of the big bright projectors. Like a 6000 lumen unit.
There is a really cool Panasonic projector I have worked with recently
and the model has escaped my brain cells. It is a 6K lumen unit
that I can carry up the stairs in the theatre by myself. I'll have
to follow-up with the model. it is real bright and portable.
There will be many challenges for these tricks, but if your director
is co-operative you should be able to do some cool things. I also
hope your producer has a fat wallet since these projectors are not
cheap. I would also suggest hiring a good projectionist with film
To sum up, it is not so crazy an idea and can be cool is everyone
I hope some of our brethren chime in who have shot more of these.
