out in my town of Brentwood in Deepest Essex, I saw the effect of aircraft vapour trails in the sky over the churchyard -- I had my 2002 Hasselblad 501CM to finish up some film, so I quickly held a Red filter over the lens. Film was 2006 dated Ilford Delta 400 rated at 250 ASA, home-processed in some D76 1+1.
