Given the discussion among various threads regarding processing techniques and H ABS/HAER requirements, I have come across a subject that may prompt some interes ting responses in this forum. I recently received a publication from the Nation al Park Service entitled HABS/HAER Photography: Specifications and Guidelines. The guidelines require that all film must be processed by hand using the dip an d dunk technique with tanks and hangers -- no tray development or use of automa tic processing equipment. This publication specifically states that "Films and prints developed by automatic processing machines have repeatedly failed stabili ty tests are are not considered archival." I have alway thought that archival s tability could be obtained using a variety of development methods, as long as on e paid close attention to proper fixing, clearing and washing techniques. Comme nts, anyone?
