A very Ancient tree on Shenfield Common, BRENTWOOD, Essex ( England) did not survive the Winter Storms -- it had been there for hundreds of years on the ancient open space. I used my A-1 + FD SSC 100mm f2.8 lens @ f4 and 03/2005 dated Fuji REALA 100 rated 80 ASA and home-processed in C41 . That same batch needs to be rated 50 ASA metering with a Weston Master V and my FTbn .
