Digital cameras Obtaining photographs and incorporating them in desktop published material often presents problems. The recent release of the Logitech digital camera indicates that a reasonable solution to this problem may be available soon. The Logitech camera takes monochrome photographs that can be transferred from the camera to a computer via the communications port. Provided they are taken in good lighting conditions the photographs are acceptable for educational materials. While the use of colour is not recommended for large blocks of text, as it makes the text difficult to read, colour can be used to highlight keywords.
Colour can be very useful in graphics such as charts and diagrams.
A range of recent developments has made the production of colour materials much easier. Colour production also presents storage problems as files containing colour graphics are usually too large for storage on floppy disks. The colour inkjet printers now appearing on the market can be used to produce colour overhead projector transparencies and colour posters of A3 size at reasonable cost. While special paper is recommended for best results they give reasonable quality on standard paper. Colour scanners Colour scanners are now available for the same price as black and white scanners were a year ago.
