Processing Procedures and Philosophy 
Photographic Processing 
The ALS operates a modern, high quality scientific photographic 
laboratory. It is equipped with a standard range of printers, enlargers 
and through-the-wall processors for colour and black & white film and 
paper processing. 
The technology is well established and literature on the subject is 
extensive. However, in many respects, imagery is the shopfront product by 
which any Landsat station is judged. The essentials to provide quality 
products are high quality equipment, rigid process control, absolute 
cleanliness and conscientious inspection procedures. 
In summary, to provide an economical service which is responsive to the 
Australian user community needs, the ALS has developed procedures and 
streamlined its systems to: 
- ensure the quality of the data archive; 
- generate timely and comprehensive catalogues; 
= provide speedy and reliable turn-around on orders. 
Because bulk processed products constitute the majority of the orders, 
special effort has been expended in streamlining the bulk processing 
system. Specific areas in which improvements have been made include: 
- progressive simplification of  operator/computer dialogue 
resulting in substantial time saving and a significant drop in 
operator errors;
