Mono Exposure using Filters
From starting out using a 35mm point and shoot Canon! I realise that I have been complacent on correct exposure. eg a K8 registers just a half stop difference with TTL metering but the filter factor reads 1.5 stops! The advice is test and so far I find 2/3rd - 1 stop max. Not so good news for all who are trying to be within 1/3 stop!
As this weather is preventing further testing, any further experiences you'all
many thanks, Hughes.
