circa 1987....pre 2001 8^)
Looking at this Fujichrome slide (ASA 50), I recorded the following:
f2.8, 55 microNikkor (I think), 9 hrs. exposure
1 full manual flash blue filter E & W
2 fmf blue filter S. face
1 f5.6 auto flash on flag
2 to 3 hours of candle inside
3 fmf red filter inside
3 fmf yellow inside
f2.8 auto flash on solar panels
also clear flash on & behind 'monolith' and on tree
Pays to take notes. 8^)
