Documenting the condition of a stained glass window prior to, during and after intervention is very important as it is the means of allowing future conservators to know what has been done to the window, what materials have been used and to understand the reasons why certain decisions have been made regarding the extent of intervention.

Photographs are the primary source of documentation augmented with written and diagrammatical explanations of the conditions encountered.  Photographs are taken internally and externally in both reflected and transmitted light of each full panel along with close up details of particular problem areas.  These photographs will be useful in the future for monitoring any change in the condition of the window.

Traditionally, full scale rubbings of a window were used to indicate particular problems or areas of intervention but more often these days, documentation is undertaken digitally.  On a project the size of a cathedral, the sheer bulk and quantity of detail involved in documentation can be quite daunting and an archivists nightmare.  With digital recording, retrieval of a specific area of interest is quite straight forward and precise.
