Many thanks to all for the help with issue with patterson spirals, Ive now made up what i lost in trashed film.
So as Ive now sorted the processing issues i decided to run a roll of delta 400 onto a 620 spool and shoot it using my kodak Junior 2. what we have here is a test roll metering taken from my mamiya 645 super and processed at 1+1 in perceptol and scanned.The site is a former tin mine processing site on the north Cornwall coast.







many thanks
