Filters
Some points about filters, apart from changing colours
of the projected images, other uses might not be so
obvious, for example plate 49
(Poetic Portfolio) is a case where the colour
change was more effective than any masking. The
idea was to combine the lamb slide with one of clouds,
but in order to mask the white clouds where they
overlapped the white lambs it was found that far too
much brilliance was lost. But by changing the
clouds to blue no masking was then needed.
Plate 30 (above) was created by photographing
the projected two identical slides of the Disneyland
castle. However one slide was projected the
wrong way round, with the two towers aligned, hoping to
create a more magical look. It turned out to
be rather disappointing! It looked very
obvious that one slide was on top of the other, none of
the magic here, even with some careful masking. But
soon it was completely transformed simply by using
filters, a pink colour in one, and blue in the other,
these colours alone killed some of the unwanted
overlapping images and so improved the scene
dramatically.
All these studies have been created by projecting on to
a screen, but they could just as easily, have been on to
a texture if one had wished.

More Projectors
There are no reasons why more than two images should not
be projected all at once, providing the projectors are
available.
There have been a number of occasions when four projectors
were in use together. However, three have been the
most that have normally been used, with the fourth one
occasionally; simply projecting the author's signature in
to the scene. As an example see plate 31 (above),
each portrait was projected individually, masked to blend
together, and then the third transparency was of a part of
an antique rice paper water colour painting, owned by the
author. Most of this image was masked away leaving
just the parts in view around the portraits.
Incidentally, a signature, or in fact any text can be
easily added to the picture. If the signature, or
text required, is written in black on a white page, it can
then be photographed with black and white film. The
negative created now provides the signature, or text, in
white against black. By projecting this negative, with a
filter placed behind it, it can be made to appear in any
colour desired.
