Comparisons between the skiing areas of Kosciusko National Park and overseas should be made with a great deal of caution. The skiing areas of the northern hemisphere are in temperate high latitude areas receiving extensive snow falls. By comparison, the Kosciusko resorts are in the same latitude as the African side of the Mediterranean Sea! In addition, ski field developments in Australia are all at or above the tree line, and in ecological terms are effectively far higher in the mountains than most of their overseas counterparts. There are very few examples overseas of ski resorts which are developed in environments as restricted in their continental distribution or as fragile as the alpine area of Kosciusko National Park. The international importance of the Park was officially acknowledged in January 1977, when it was designated a Biosphere Reserve under UNESCO' | Comparisons between the skiing areas of Kosciusko National Park and overseas should be made with a great deal of caution.

- | Significant damage has occurred in the area due to the developments. Recent examples are the major oil spill of winter 1979, and the extensive -soil erosion that required urgent remedial works. The effect of nutrients from sewage treatment is clearly evident in Spencers Creek. The damage to the David Moraine by electrical reticulation works, road works and snow clearing are other examples.

+ | Compared to the chemistry of colour film the physics of lenses are simple. All brands of colour film are three sensitive layers of emulsion on a backing. Each layer is sensitive to one colour alone - magenta, cyan and green/blue. Green/blue is generally the least successfully formulated and in addition has the most variable sensitivity to our eyes. Fresh colour film of different brands, even if all daylight type, will have inherently different response to these colours, a deliberate-choice of the manufacturer. Kodachrame seems to have saturated blues at the expense of magenta, Agfa gives de-saturated reds and browns and its blue is unpredictable. Ektachrome gives good saturation across the spectrum; specifically Ektachrome " | ||
