Colour Prints . Can be made to order, either from the whole or part of the negative. Stereo Pairs . This allows the overlapping area to be viewed three-dimensionally. Contours can be drawn, and heights and volumes estimated.
Special equipment is needed.
Older Photographs . They are useful as a historical record and, in conjunction with the more recent photographs, for showing changes that have taken place over the years. As digitising such photographs in high definition would have resulted in unrealistically large files and therefore very long download times, we have made a compromise and digitised a small section of each one at only 300 dpi. The figures in brackets after the photograph descriptions are approximate file sizes.
